60 Bug fix; removed a combinational loop from the a25_decode logic. csantifort 4903d 19h /amber/trunk/
59 Added modelsim script for reloading a wlf file after a simulation has been rerun. csantifort 4973d 16h /amber/trunk/
58 Use TB.clk_count for the decompiler messages and removed the local counter csantifort 4973d 20h /amber/trunk/
57 Add some debug messages csantifort 4973d 20h /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 4990d 19h /amber/trunk/
53 Cleaned up Amber Verilog, removing unused signals. csantifort 5005d 17h /amber/trunk/
52 Fixed typo in notes on creating DDR memory interfaces using coregen csantifort 5005d 17h /amber/trunk/
51 Revert vmlinux back to 48. csantifort 5046d 17h /amber/trunk/
50 Revert to previous version csantifort 5046d 17h /amber/trunk/
49 Added a note n how to change timeouts csantifort 5046d 17h /amber/trunk/

44 Updated vmlinux image based on last change csantifort 5078d 19h /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 5078d 19h /amber/trunk/
42 Added write buffer - fixes bug if wishbone writes takes multiple cycles to complete csantifort 5096d 16h /amber/trunk/
41 Added instructions on how to use Coregen to create the Spartan-6 DDR3 memory interface. csantifort 5098d 00h /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 5102d 17h /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 5103d 18h /amber/trunk/
38 support 128-bit wishbone now used for a25 core csantifort 5104d 17h /amber/trunk/
37 128-bit wide boot memory module csantifort 5105d 16h /amber/trunk/
36 Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus csantifort 5105d 17h /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 5107d 00h /amber/trunk/
34 Tweaked strcpy function to speed it up slightly csantifort 5107d 21h /amber/trunk/
33 Fixed bug in div assembly function. Handles negative numbers correctly.
