47 Tag version 0.1 of the Potato Processor skordal 3288d 01h /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 3290d 20h /potato/trunk/
36 Ensure correct read of CSR after stall skordal 3290d 21h /potato/trunk/
35 Prevent jumping/branching when stalling skordal 3290d 21h /potato/trunk/
34 Prevent flushing the pipeline if it is stalling skordal 3290d 21h /potato/trunk/
28 Add rudimentary User's manual skordal 3304d 19h /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 3304d 23h /potato/trunk/
24 Remove unused STRINGIFY macros skordal 3307d 17h /potato/trunk/
22 Fix the potato_get_badvaddr() macro skordal 3307d 18h /potato/trunk/
21 Upgrade the example design to use a 60 MHz system clock skordal 3307d 18h /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 3307d 18h /potato/trunk/
19 SHA256 benchmark: allow compiler to inline at will skordal 3307d 18h /potato/trunk/
18 instr_misalign_check: add do_jump to sensitivity list skordal 3309d 18h /potato/trunk/
17 Improve detection of unaligned instructions skordal 3314d 01h /potato/trunk/
16 Correct grammar in source code comment skordal 3314d 01h /potato/trunk/
15 SHA256 benchmark: fix Makefile syntax error skordal 3320d 18h /potato/trunk/
14 Improve detection of invalid instructions skordal 3320d 19h /potato/trunk/
13 Add SHA256 benchmark code skordal 3320d 23h /potato/trunk/
12 Update example design with correct bug-report URL and testbenches skordal 3321d 01h /potato/trunk/
11 Correct FIFO file header skordal 3321d 01h /potato/trunk/
