3532ae0b79 From Andrew, actually mark scoreboard when rocc instruction with a writeback is issued. Also, fix an issue with AccumulatorExample not properly tagging its memory requests. Finally, reverted changes from f27429c to more properly follow the spike model (always return previous value of accumulator). 2013-09-24 10:54:09 -07:00
