44 Updated vmlinux image based on last change csantifort 4773d 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 4773d 19h /amber/trunk
42 Added write buffer - fixes bug if wishbone writes takes multiple cycles to complete csantifort 4791d 15h /amber/trunk
41 Added instructions on how to use Coregen to create the Spartan-6 DDR3 memory interface. csantifort 4793d 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 4797d 16h /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 4798d 17h /amber/trunk
38 support 128-bit wishbone now used for a25 core csantifort 4799d 17h /amber/trunk
37 128-bit wide boot memory module csantifort 4800d 15h /amber/trunk
36 Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus csantifort 4800d 16h /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 4801d 23h /amber/trunk
34 Tweaked strcpy function to speed it up slightly csantifort 4802d 20h /amber/trunk
33 Fixed bug in div assembly function. Handles negative numbers correctly.
Fixed bug in printf function, negative numbers now print correctly.		 csantifort 4803d 16h /amber/trunk
32 Added clock cycle counting register to test_module to support dhrystone performance measurement csantifort 4804d 17h /amber/trunk
31 Added dhrystone benchmark test csantifort 4804d 17h /amber/trunk
30 Bug fix - a write access was sometimes dropped when it was in a sequence of writes with variable wb_ack delays csantifort 4817d 23h /amber/trunk
29 Use lgo command for saving waveforms in modelsim csantifort 4819d 17h /amber/trunk
28 Moved function prototypes to .h file csantifort 4819d 17h /amber/trunk
27 Got working with cadence nc simulator csantifort 4853d 00h /amber/trunk
26 Added wish list csantifort 4858d 00h /amber/trunk
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 4859d 22h /amber/trunk
