60 Bug fix; removed a combinational loop from the a25_decode logic. csantifort 4567d 17h /amber/trunk/
59 Added modelsim script for reloading a wlf file after a simulation has been rerun. csantifort 4637d 15h /amber/trunk/
58 Use TB.clk_count for the decompiler messages and removed the local counter csantifort 4637d 18h /amber/trunk/
57 Add some debug messages csantifort 4637d 18h /amber/trunk/

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 4654d 18h /amber/trunk/
53 Cleaned up Amber Verilog, removing unused signals. csantifort 4669d 16h /amber/trunk/
52 Fixed typo in notes on creating DDR memory interfaces using coregen csantifort 4669d 16h /amber/trunk/
51 Revert vmlinux back to 48. csantifort 4710d 15h /amber/trunk/
50 Revert to previous version csantifort 4710d 16h /amber/trunk/

44 Updated vmlinux image based on last change csantifort 4742d 18h /amber/trunk/
43 Added support for the flat executable file format to vmlinux, so that the hello-world program is correctly relocated when it is loaded at the end of the vmlinux test.
Changed the Virtex-5 clock configuration to use a 1200MHz VCO frequency and 80MHz system clock frequency.		 csantifort 4742d 18h /amber/trunk/
42 Added write buffer - fixes bug if wishbone writes takes multiple cycles to complete csantifort 4760d 14h /amber/trunk/
41 Added instructions on how to use Coregen to create the Spartan-6 DDR3 memory interface. csantifort 4761d 23h /amber/trunk/
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 4766d 15h /amber/trunk/
39 Added a second level of buffering to a25_wishbone_buf to fix a lockup
bug when write acks to not return immediately, and also to improve performance slightly		 csantifort 4767d 16h /amber/trunk/
38 support 128-bit wishbone now used for a25 core csantifort 4768d 16h /amber/trunk/
37 128-bit wide boot memory module csantifort 4769d 14h /amber/trunk/
36 Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus csantifort 4769d 15h /amber/trunk/
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 4770d 22h /amber/trunk/
34 Tweaked strcpy function to speed it up slightly csantifort 4771d 19h /amber/trunk/
33 Fixed bug in div assembly function. Handles negative numbers correctly.
