44	Updated vmlinux image based on last change	csantifort	4917d 17h	/
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	4917d 17h	/
42	Added write buffer - fixes bug if wishbone writes takes multiple cycles to complete	csantifort	4935d 13h	/
41	Added instructions on how to use Coregen to create the Spartan-6 DDR3 memory interface.	csantifort	4936d 22h	/
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	4941d 14h	/
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	4942d 15h	/
38	support 128-bit wishbone now used for a25 core	csantifort	4943d 15h	/
37	128-bit wide boot memory module	csantifort	4944d 13h	/
36	Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus	csantifort	4944d 14h	/
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	4945d 21h	/
34	Tweaked strcpy function to speed it up slightly	csantifort	4946d 18h	/
33	Fixed bug in div assembly function. Handles negative numbers correctly. Fixed bug in printf function, negative numbers now print correctly.	csantifort	4947d 14h	/
32	Added clock cycle counting register to test_module to support dhrystone performance measurement	csantifort	4948d 15h	/
31	Added dhrystone benchmark test	csantifort	4948d 15h	/
30	Bug fix - a write access was sometimes dropped when it was in a sequence of writes with variable wb_ack delays	csantifort	4961d 21h	/
29	Use lgo command for saving waveforms in modelsim	csantifort	4963d 15h	/
28	Moved function prototypes to .h file	csantifort	4963d 15h	/
27	Got working with cadence nc simulator	csantifort	4996d 22h	/
26	Added wish list	csantifort	5001d 22h	/
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	5003d 20h	/
