68 Remove modelsim files. Only supporting Xilinx isim now. csantifort 4059d 03h /amber/trunk/hw/tools/
63 Add support for Xilinx ISim Verilog simulator.
Remove Virtex-6 files.
csantifort 4059d 08h /amber/trunk/hw/tools/
61 Add new netowkr based boot loader.
Remove support for Virtex. Spartan 6 only now.
csantifort 4346d 02h /amber/trunk/hw/tools/
56 Remove the timeouts file from svn. Its an output file and gets now just gets created automatically
when sims are run for the first time.
csantifort 4633d 23h /amber/trunk/hw/tools/
54 Bug fix for bug reported by Botao Lee. The mode bits in the decode stage did not change immediately
after a mode switch from a teqp instruction, but 1 cycle later. This meant the wrong set of registers
was selected for writing to for 1 clock cycle.
csantifort 4650d 23h /amber/trunk/hw/tools/
48 Fixed a bug in linux that caused the os to not return to the running application after an interrupt.
Hello-world now runs stand-alone again.
Added initrd-200k-dhry, a disk image that uses the dhry program for init.
csantifort 4711d 03h /amber/trunk/hw/tools/
45 Store vmlinux.mem and vmlinux.dis in compressed form csantifort 4738d 22h /amber/trunk/hw/tools/
40 Added wishbone bus jitter testing option.
Cleaned up waveform log .do files, now seperate files for a23 and a25 cores.
Added vmlinux executable elf file for running on hardware.
csantifort 4762d 20h /amber/trunk/hw/tools/
36 Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus csantifort 4765d 20h /amber/trunk/hw/tools/
35 Amber25 improvements:
Use 128-bit wishbone bus, instead of 32-bit to reduce cache miss fetch times
Use a fast barrel shifter for shifts between 0 and 4 to improve timing
Use a 2 cycle full barrel shifter for complex shifts
csantifort 4767d 04h /amber/trunk/hw/tools/
29 Use lgo command for saving waveforms in modelsim csantifort 4784d 21h /amber/trunk/hw/tools/
25 Bug fix: boot-loader.mem became larger that the allowed 8k byte boot mem size.
Removed a struct in elfsplitter.c thats only used for debug - this reduced boot-loader.mem enough so that it fits again.
Tidy up: Removed a debug message from hw/tools/run.sh
csantifort 4825d 02h /amber/trunk/hw/tools/
20 Added feature to A25 core to directly use a read value from the write back stage
to reduce the stall to 1 cycle when there is a register conflict with the
following instruction. This increases performance by about 3%.
csantifort 4852d 03h /amber/trunk/hw/tools/
17 amber25 core bug fix. The return address for irq interrupts was off by 4 bytes
when the interrupt occurred during a stm instruction with the following instruction
having some register conflicts. Added test irq_stm to catch the bug.
Cleaned up some header descriptions
csantifort 4856d 01h /amber/trunk/hw/tools/
15 Copied amber to amber23, Many system changes to support new amber25 core. csantifort 4858d 15h /amber/trunk/hw/tools/
11 Added vmlinux test. csantifort 4875d 03h /amber/trunk/hw/tools/
2 Baseline release of the Amber 2 core csantifort 4889d 01h /amber/trunk/hw/tools/
