611ea6882d Changed FDivBusyE to stall the whole pipeline. Any instruction in the Executation which depended on the output of an instruction in the writeback stage would be lost if the back end of the pipelined advanced. The solution is to stall the whole pipeline. 2022-10-22 16:27:20 -05:00

de1e569ee9 Noted possible bug with endianness during hptw. 
Minor complexity reduction in interlockfsm.  I think there is a lot of room to simplify.
