Rev Log message Author Age Path
16 - assembler update: assembler can now include other files using the ".include" statement
- doc update: fixed error in instruction summary table		 zero_gravity 4091d 02h /atlas_core/
15 - new instruction added: NEG Rd, Rx (Rd <- 0 - Ra)
- instruction is built from redundant SUB with identical operands (SUB Rd, Ra, Ra; will always result in 0)
- since there are other instructions to clear a register, the redundant SUB has been recoded to perform the NEG operation
- NEG operation added to documentary and assembler		 zero_gravity 4098d 03h /atlas_core/
14 - instruction set summary card added to documentary (Atlas Processor Datasheet)
- minor edits in SYS_REG.vhd and ATLAS_pkg.vhd files		 zero_gravity 4098d 23h /atlas_core/
13 - new option added to the RT/GT/STPC instructions
- ATLAS_MICRO implementation scheme added (+testbench)
- huge DOC update		 zero_gravity 4113d 19h /atlas_core/
12 - assembler: dev c++ project changed to 32-bit
- atlas_asm.exe is now compiled for 32-bit system		 zero_gravity 4136d 00h /atlas_core/
11 - optimized memory components
-> less access hardware
-> easier mapping for quartus sythesis tool		 zero_gravity 4138d 18h /atlas_core/
10 - optimized opcode decoder
- deleted HALT signal from Atlas Micro - not feasible here
- doc update		 zero_gravity 4138d 20h /atlas_core/
9 - ATLAS_MICRO implementation example added to project (CPU + I/D memory) zero_gravity 4139d 21h /atlas_core/
8 - bug-fix: MSR read access
- new instruction added: SPR (store parity of register to T-flag)
- doc update
- assembler update		 zero_gravity 4139d 22h /atlas_core/
7 - data path diagram added to documentary (finally!!)
- updated assembler version
- updated assembler examples		 zero_gravity 4142d 23h /atlas_core/
6 - more code examples added to documentary
- minor updates for RTL files
- assembler now supports binary and hexadecimal number representation		 zero_gravity 4145d 21h /atlas_core/
5 - error corrected in data sheet's branch table asm example zero_gravity 4151d 02h /atlas_core/
4 - complete update zero_gravity 4151d 02h /atlas_core/
3 - bug-fix of compare/test instruction in assembler program
- minor edits in rtl files to make a more efficient use of config constants		 zero_gravity 4152d 19h /atlas_core/
2 initial repository setup zero_gravity 4153d 21h /atlas_core/
1 The project and the structure was created root 4153d 21h /atlas_core/
