41 Added instructions on how to use Coregen to create the Spartan-6 DDR3 memory interface. csantifort 4882d 00h /
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 4886d 16h /
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 4887d 17h /
38 support 128-bit wishbone now used for a25 core csantifort 4888d 17h /
37 128-bit wide boot memory module csantifort 4889d 15h /
36 Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus csantifort 4889d 16h /
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 4890d 23h /
34 Tweaked strcpy function to speed it up slightly csantifort 4891d 20h /
33 Fixed bug in div assembly function. Handles negative numbers correctly.
Fixed bug in printf function, negative numbers now print correctly.
csantifort 4892d 16h /
32 Added clock cycle counting register to test_module to support dhrystone performance measurement csantifort 4893d 17h /
31 Added dhrystone benchmark test csantifort 4893d 17h /
30 Bug fix - a write access was sometimes dropped when it was in a sequence of writes with variable wb_ack delays csantifort 4906d 23h /
29 Use lgo command for saving waveforms in modelsim csantifort 4908d 17h /
28 Moved function prototypes to .h file csantifort 4908d 17h /
27 Got working with cadence nc simulator csantifort 4942d 00h /
26 Added wish list csantifort 4947d 00h /
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 4948d 22h /
24 Added instructions how to build Linux kernel from source files csantifort 4950d 22h /
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 4950d 23h /
22 Added files and instructions to enable the building of the vmlinux image from the kernel source files. csantifort 4954d 22h /
