47 Tag version 0.1 of the Potato Processor skordal 3263d 06h /potato/tags/v0.1/
45 Merge branch cache-playground (r23-r30 and r34-r44) into trunk

This primarily adds the following features the the processor:
- A direct-mapped instruction cache with configurable cache line width and
number of cache lines.
- Various bug fixes for bugs that appeared when the processor could run
instructions at full speed but had to stall for data.
- A "Hello World" test application.		 skordal 3266d 00h /potato/trunk/
36 Ensure correct read of CSR after stall skordal 3266d 02h /potato/trunk/
35 Prevent jumping/branching when stalling skordal 3266d 02h /potato/trunk/
34 Prevent flushing the pipeline if it is stalling skordal 3266d 02h /potato/trunk/
28 Add rudimentary User's manual skordal 3279d 23h /potato/trunk/
26 Prevent exceptions from being taken while stalling

Jumping to an exception handler while stalling and waiting for a load/store
instruction to finish can cause undefined results from the load/store
instruction. This actually fixes the issue mentioned in revision r20.		 skordal 3280d 04h /potato/trunk/
24 Remove unused STRINGIFY macros skordal 3282d 21h /potato/trunk/
22 Fix the potato_get_badvaddr() macro skordal 3282d 22h /potato/trunk/
21 Upgrade the example design to use a 60 MHz system clock skordal 3282d 22h /potato/trunk/
20 Fix SHA256 benchmark crash by storing all registers on exception handler entry

This problem will disappear when the processor is updated to conform to the
new supervisor specification, which will allow us to use a compiler that
conforms to the new "official" ABI.		 skordal 3282d 22h /potato/trunk/
19 SHA256 benchmark: allow compiler to inline at will skordal 3282d 22h /potato/trunk/
18 instr_misalign_check: add do_jump to sensitivity list skordal 3284d 22h /potato/trunk/
17 Improve detection of unaligned instructions skordal 3289d 05h /potato/trunk/
16 Correct grammar in source code comment skordal 3289d 05h /potato/trunk/
15 SHA256 benchmark: fix Makefile syntax error skordal 3295d 22h /potato/trunk/
14 Improve detection of invalid instructions skordal 3295d 23h /potato/trunk/
13 Add SHA256 benchmark code skordal 3296d 03h /potato/trunk/
12 Update example design with correct bug-report URL and testbenches skordal 3296d 06h /potato/trunk/
11 Correct FIFO file header skordal 3296d 06h /potato/trunk/
