Another giveaway is + that the annul flag is cleared in execute_trap(): the information + is demonstrably discarded. + + The solution is: perform annulling before looking for traps, in + fact it's neater to do annulling, see if there's an interrupt and + if not, do the instruction, then handle traps be they generated by + interrupts pending or by the instruction we might just have done. + That's what the sis.c one does. + +1999-01-20 Hugo Tyson + + * sis.h: Add asr17 register for support of SparcLITE (at least the + Hitachi ones I find before me) + + * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if + sparclite.

Introduction + +The SIS is a SPARC V7 architecture simulator. It consist of two parts, +the simulator core and a user defined memory module. The simulator +core executes the instructions while the memory module emulates memory +and peripherals. + +2. Usage + +The simulator is started as follows: + +sis [-uart1 uart_device1] [-uart2 uart_device2] + [-nfp] [-freq frequency] [-c batch_file] [files] + +The default uart devices for SIS are /dev/ptypc and /dev/ptypd. The +-uart[1,2] switch can be used to connect the uarts to other devices. +Use 'tip /dev/ttypc' to connect a terminal emulator to the uarts. +The '-nfp' will disable the simulated FPU, so each FPU instruction will +generate a FPU disabled trap. The '-freq' switch can be used to define +which "frequency" the simulator runs at. This is used by the 'perf' +command to calculated the MIPS figure for a particular configuration. +The give frequency must be an integer indicating the frequency in MHz. + +The -c option indicates that sis commands should be read from 'batch_file' +at startup. + +Files to be loaded must be in one of the supported formats (see INSTALLATION), +and will be loaded into the simulated memory. The file formats are +automatically recognised. + +The script 'startsim' will start the simulator in one xterm window and +open a terminal emulator (tip) connected to the UART A in a second +xterm window. Below is description of commands that are recognized by +the simulator. The command-line is parsed using GNU readline. A command +history of 64 commands is maintained. Use the up/down arrows to recall +previous commands. For more details, see the readline documentation. + +batch + +Execute a batch file of SIS commands. + ++bp

+ +Adds an breakpoint at address

. + +bp + +Prints all breakpoints + +-bp + +Deletes breakpoint . Use 'bp' to see which number is assigned to the +breakpoints. + +cont [inst_count] + +Continue execution at present position, optionally for [inst_count] +instructions. + +dis [addr] [count] + +Disassemble [count] instructions at address [addr]. Default values for +count is 16 and addr is the present address. + +echo + +Print to the simulator window. + +float + +Prints the FPU registers + +go

[inst_count] + +The go command will set pc to

and npc to

+ 4, and start +execution. No other initialisation will be done. If inst_count is given, +execution will stop after the specified number of instructions. + +help + +Print a small help menu for the SIS commands. + +hist [trace_length] + +Enable the instruction trace buffer. The 'trace_length' last executed +instructions will be placed in the trace buffer. A 'hist' command without +a trace_length will display the trace buffer. Specifying a zero trace +length will disable the trace buffer. + +load + +Loads a file into simulator memory. + +mem [addr] [count] + +Display memory at [addr] for [count] bytes. Same default values as above. + +quit + +Exits the simulator. + +perf [reset] + +The 'perf' command will display various execution statistics. A 'perf reset' +command will reset the statistics. This can be used if statistics shall +be calculated only over a part of the program. The 'run' and 'reset' +command also resets the statistic information. + +reg [reg_name] [value] + +Prints and sets the IU regiters. 'reg' without parameters prints the IU +registers. 'reg [reg_name] [value]' sets the corresponding register to +[value]. Valid register names are psr, tbr, wim, y, g1-g7, o0-o7 and +l0-l7. + +reset + +Performs a power-on reset. This command is equal to 'run 0'. + +run [inst_count] + +Resets the simulator and starts execution from address 0. If an instruction +count is given (inst_count), the simulator will stop after the specified +number of instructions. The event queue is emptied but any set breakpoints +remain. + +step + +Equal to 'trace 1' + +tra [inst_count] + +Starts the simulator at the present position and prints each instruction +it executes. If an instruction count is given (inst_count), the simulator +will stop after the specified number of instructions. + +Typing a 'Ctrl-C' will interrupt a running simulator. + +Short forms of the commands are allowed, e.g 'c' 'co' or 'con' are all +interpreted as 'cont'. + + +3. Simulator core + +The SIS emulates the behavior of the 90C601E and 90C602E sparc IU and +FPU from Matra MHS. These are roughly equivalent to the Cypress C601 +and C602. The simulator is cycle true, i.e a simulator time is +maintained and inremented according the IU and FPU instruction timing. +The parallel execution between the IU and FPU is modelled, as well as +stalls due to operand dependencies (FPU). The core interacts with the +user-defined memory modules through a number of functions. The memory +module must provide the following functions: + +int memory_read(asi,addr,data,ws) +int asi; +unsigned int addr; +unsigned int *data; +int *ws; + +int memory_write(asi,addr,data,sz,ws) +int asi; +unsigned int addr; +unsigned int *data; +int sz; +int *ws; + +int sis_memory_read(addr, data, length) +unsigned int addr; +char *data; +unsigned int length; + +int sis_memory_write(addr, data, length) +unsigned int addr; +char *data; +unsigned int length; + +int init_sim() + +int reset() + +int error_mode(pc) +unsigned int pc; + +memory_read() is used by the simulator to fetch instructions and +operands. The address space identifier (asi) and address is passed as +parameters. The read data should be assigned to the data pointer +(*data) and the number of waitstate to *ws. 'memory_read' should return +0 on success and 1 on failure. A failure will cause a data or +instruction fetch trap. memory_read() always reads one 32-bit word. + +sis_memory_read() is used by the simulator to display and disassemble +memory contants. The function should copy 'length' bytes of the simulated +memory starting at 'addr' to '*data'. +The sis_memory_read() should return 1 on success and 0 on failure. +Failure should only be indicated if access to unimplemented memory is attempted. + +memory_write() is used to write to memory. In addition to the asi +and address parameters, the size of the written data is given by 'sz'. +The pointer *data points to the data to be written. The 'sz' is coded +as follows: + + sz access type + 0 byte + 1 halfword + 2 word + 3 double-word + +If a double word is written, the most significant word is in data[0] and +the least significant in data[1]. + +sis_memory_write() is used by the simulator during loading of programs. +The function should copy 'length' bytes from *data to the simulated +memory starting at 'addr'. sis_memory_write() should return 1 on +success and 0 on failure. Failure should only be indicated if access +to unimplemented memory is attempted. See erc32.c for more details +on how to define the memory emulation functions. + +The 'init_sim' is called once when the simulator is started. This function +should be used to perform initialisations of user defined memory or +peripherals that only have to be done once, such as opening files etc. + +The 'reset' is called every time the simulator is reset, i.e. when a +'run' command is given. This function should be used to simulate a power +on reset of memory and peripherals. + +error_mode() is called by the simulator when the IU goes into error mode, +typically if a trap is caused when traps are disabled. The memory module +can then take actions, such as issue a reset. + +sys_reset() can be called by the memory module to reset the simulator. A +reset will empty the event queue and perform a power-on reset. + +4. Events and interrupts + +The simulator supports an event queue and the generation of processor +interrupts. The following functions are available to the user-defined +memory module: + +event(cfunc,arg,delta) +void (*cfunc)(); +int arg; +unsigned int delta; + +set_int(level,callback,arg) +int level; +void (*callback)(); +int arg; + +clear_int(level) +int level; + +sim_stop() + +The 'event' functions will schedule the execution of the function 'cfunc' +at time 'now + delta' clock cycles. The parameter 'arg' is passed as a +parameter to 'cfunc'. + +The 'set_int' function set the processor interrupt 'level'. When the interrupt +is taken, the function 'callback' is called with the argument 'arg'. This +will also clear the interrupt. An interrupt can be cleared before it is +taken by calling 'clear_int' with the appropriate interrupt level. + +The sim_stop function is called each time the simulator stops execution. +It can be used to flush buffered devices to get a clean state during +single stepping etc. + +See 'erc32.c' for examples on how to use events and interrupts. + +5. Memory module + +The supplied memory module (erc32.c) emulates the functions of memory and +the MEC asic developed for the 90C601/2. It includes the following functions: + +* UART A & B +* Real-time clock +* General purpose timer +* Interrupt controller +* Breakpoint register +* Watchpoint register +* 512 Kbyte ROM +* 4 Mbyte RAM + +See README.erc32 on how the MEC functions are emulated. For a detailed MEC +specification, look at the ERC32 home page at URL: + +http://www.estec.esa.nl/wsmwww/erc32 + +6. Compile and linking programs + +The directory 'examples' contain some code fragments for SIS. +The script gccx indicates how the native sunos gcc and linker can be used +to produce executables for the simulator. To compile and link the provided +'hello.c', type 'gccx hello.c'. This will build the executable 'hello'. +Start the simulator by running 'startsim hello', and issue the command 'run. +After the program is terminated, the IU will be force to error mode through +a software trap and halt. + +The programs are linked with a start-up file, srt0.S. This file includes +the traptable and window underflow/overflow trap routines. + +7. IU and FPU instruction timing. + +The simulator provides cycle true simulation. The following table shows +the emulated instruction timing for 90C601E & 90C602E: + +Instructions Cycles + +jmpl, rett 2 +load 2 +store 3 +load double 3 +store double 4 +other integer ops 1 +fabs 2 +fadds 4 +faddd 4 +fcmps 4 +fcmpd 4 +fdivs 20 +fdivd 35 +fmovs 2 +fmuls 5 +fmuld 9 +fnegs 2 +fsqrts 37 +fsqrtd 65 +fsubs 4 +fsubd 4 +fdtoi 7 +fdots 3 +fitos 6 +fitod 6 +fstoi 6 +fstod 2 + +The parallel operation between the IU and FPU is modelled. This means +that a FPU instruction will execute in parallel with other instructions as +long as no data or resource dependency is detected. See the 90C602E data +sheet for the various types of dependencies. Tracing using the 'trace' +command will display the current simulator time in the left column. This +time indicates when the instruction is fetched. If a dependency is detetected, +the following fetch will be delayed until the conflict is resolved. + +The load dependency in the 90C601E is also modelled - if the destination +register of a load instruction is used by the following instruction, an +idle cycle is inserted. + +8. FPU implementation + +The simulator maps floating-point operations on the hosts floating point +capabilities. This means that accuracy and generation of IEEE exceptions is +host dependent.

Since external interrupts +are not possible, the interrupt shape register is not implemented. The +only internal interrupts that are generated are the real-time clock, +the general purpose timer and UARTs. However, all 15 interrupts +can be tested via the interrupt force register. + +The following registers are implemeted: + +- Interrupt pending register (0x01f80048, read-only) +- Interrupt mask register (0x01f8004c, read-write) +- Interrupt clear register (0x01f80050, write-only) +- Interrupt force register (0x01f80054, read-write) + +1.4 Breakpoint and watchpoint register + +The breakpoint and watchpoint functions are implemented as in the MEC +specification.

However, access to unimplemented MEC registers +in the area 0x01f80000 - 0x01f80100 will not cause a memory exception trap. +The written value will be stored in a register and can be read back. It +does however not affect the function in any way. + +The memory configuartion register is used to define available memory +in the system. The fields RSIZ and PSIZ are used to set RAM and ROM +size, the remaining fields are not used. NOTE: after reset, the MEC +is set to decode 4 Kbyte of ROM and 256 Kbyte of RAM. The memory +configuration register has to be updated to reflect the available memory. + +The waitstate configuration register is used to generate waitstates. +This register must also be updated with the correct configuration after +reset. + +The memory protection scheme is implemented - it is enabled through bit 3 +in the MEC control register. + +The following registers are implemeted: + +- MEC control register (bit 3 only) (0x01f80000, read-write) +- Memory control register (0x01f80010, read-write) +- Waitstate configuration register (0x01f80018, read-write) +- Memory access register 0 (0x01f80020, read-write) +- Memory access register 1 (0x01f80024, read-write) + +1.6 Watchdog + +The watchdog is implemented as in the specification.
