44 Updated vmlinux image based on last change csantifort 4924d 13h /amber/
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 4924d 13h /amber/
42 Added write buffer - fixes bug if wishbone writes takes multiple cycles to complete csantifort 4942d 10h /amber/
41 Added instructions on how to use Coregen to create the Spartan-6 DDR3 memory interface. csantifort 4943d 18h /amber/
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 4948d 11h /amber/
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 4949d 11h /amber/
38 support 128-bit wishbone now used for a25 core csantifort 4950d 11h /amber/
37 128-bit wide boot memory module csantifort 4951d 09h /amber/
36 Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus csantifort 4951d 10h /amber/
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 4952d 18h /amber/
34 Tweaked strcpy function to speed it up slightly csantifort 4953d 14h /amber/
33 Fixed bug in div assembly function. Handles negative numbers correctly.
Fixed bug in printf function, negative numbers now print correctly.
csantifort 4954d 11h /amber/
32 Added clock cycle counting register to test_module to support dhrystone performance measurement csantifort 4955d 11h /amber/
31 Added dhrystone benchmark test csantifort 4955d 11h /amber/
30 Bug fix - a write access was sometimes dropped when it was in a sequence of writes with variable wb_ack delays csantifort 4968d 18h /amber/
29 Use lgo command for saving waveforms in modelsim csantifort 4970d 11h /amber/
28 Moved function prototypes to .h file csantifort 4970d 12h /amber/
27 Got working with cadence nc simulator csantifort 5003d 19h /amber/
26 Added wish list csantifort 5008d 19h /amber/
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 5010d 16h /amber/
