45 Store vmlinux.mem and vmlinux.dis in compressed form csantifort 4986d 11h /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 5010d 09h /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 5013d 09h /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

29 Use lgo command for saving waveforms in modelsim csantifort 5032d 10h /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 5072d 14h /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 5099d 16h /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
