[/] [amber/] [trunk/] [hw/] - Rev 65

Rev	Log message	Author	Age	Path
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	4814d 18h	/amber/trunk/hw/
38	support 128-bit wishbone now used for a25 core	csantifort	4815d 18h	/amber/trunk/hw/
37	128-bit wide boot memory module	csantifort	4816d 16h	/amber/trunk/hw/
36	Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus	csantifort	4816d 17h	/amber/trunk/hw/
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	4818d 01h	/amber/trunk/hw/
32	Added clock cycle counting register to test_module to support dhrystone performance measurement	csantifort	4820d 18h	/amber/trunk/hw/
30	Bug fix - a write access was sometimes dropped when it was in a sequence of writes with variable wb_ack delays	csantifort	4834d 00h	/amber/trunk/hw/
29	Use lgo command for saving waveforms in modelsim	csantifort	4835d 18h	/amber/trunk/hw/
27	Got working with cadence nc simulator	csantifort	4869d 01h	/amber/trunk/hw/
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	4875d 23h	/amber/trunk/hw/
