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 4918d 18h /amber/trunk/hw/vlog/amber25/a25_wishbone_buf.v
36 Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus csantifort 4920d 17h /amber/trunk/hw/vlog/amber25/a25_wishbone_buf.v
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
