45	Store vmlinux.mem and vmlinux.dis in compressed form	csantifort	4995d 00h	/
44	Updated vmlinux image based on last change	csantifort	4995d 00h	/
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	4995d 00h	/
42	Added write buffer - fixes bug if wishbone writes takes multiple cycles to complete	csantifort	5012d 20h	/
41	Added instructions on how to use Coregen to create the Spartan-6 DDR3 memory interface.	csantifort	5014d 05h	/
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	5018d 21h	/
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	5019d 22h	/
38	support 128-bit wishbone now used for a25 core	csantifort	5020d 22h	/
37	128-bit wide boot memory module	csantifort	5021d 20h	/
36	Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus	csantifort	5021d 21h	/
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	5023d 05h	/
34	Tweaked strcpy function to speed it up slightly	csantifort	5024d 01h	/
33	Fixed bug in div assembly function. Handles negative numbers correctly. Fixed bug in printf function, negative numbers now print correctly.	csantifort	5024d 21h	/
32	Added clock cycle counting register to test_module to support dhrystone performance measurement	csantifort	5025d 22h	/
31	Added dhrystone benchmark test	csantifort	5025d 22h	/
30	Bug fix - a write access was sometimes dropped when it was in a sequence of writes with variable wb_ack delays	csantifort	5039d 04h	/
29	Use lgo command for saving waveforms in modelsim	csantifort	5040d 22h	/
28	Moved function prototypes to .h file	csantifort	5040d 23h	/
27	Got working with cadence nc simulator	csantifort	5074d 05h	/
26	Added wish list	csantifort	5079d 06h	/
