I released Version_0-005 yesterday, which implements the remaining instructions in the load_add_store.s program listed in my FSS Version_0-004 blog entry. This completes a round-trip datapath, with operands coming from offchip (i.e. simulated memory in the testbench) and arithmetic results emerging from the chip (i.e. stored in simulated memory). Unlike the previous version, for this release I did verify that the execution was correct (for the test cases that I simulated).
