41 Added instructions on how to use Coregen to create the Spartan-6 DDR3 memory interface. csantifort 5139d 17h /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 5144d 10h /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 5145d 10h /amber/
38 support 128-bit wishbone now used for a25 core csantifort 5146d 10h /amber/
37 128-bit wide boot memory module csantifort 5147d 09h /amber/
36 Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus csantifort 5147d 09h /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 5148d 17h /amber/
34 Tweaked strcpy function to speed it up slightly csantifort 5149d 14h /amber/
33 Fixed bug in div assembly function. Handles negative numbers correctly.
Fixed bug in printf function, negative numbers now print correctly.
csantifort 5150d 10h /amber/
32 Added clock cycle counting register to test_module to support dhrystone performance measurement csantifort 5151d 10h /amber/
31 Added dhrystone benchmark test csantifort 5151d 10h /amber/
30 Bug fix - a write access was sometimes dropped when it was in a sequence of writes with variable wb_ack delays csantifort 5164d 17h /amber/
29 Use lgo command for saving waveforms in modelsim csantifort 5166d 10h /amber/
28 Moved function prototypes to .h file csantifort 5166d 11h /amber/
27 Got working with cadence nc simulator csantifort 5199d 18h /amber/
26 Added wish list csantifort 5204d 18h /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 5206d 15h /amber/
24 Added instructions how to build Linux kernel from source files csantifort 5208d 15h /amber/
23 Split the source files list into a Vertex-6 only list and a Spartan-6 only list.
That way users don;t need to delete files from the list manually if they only have
a setup for one of the FPGA types.
csantifort 5208d 16h /amber/
22 Added files and instructions to enable the building of the vmlinux image from the kernel source files. csantifort 5212d 15h /amber/
