Annul instruction if the I/O write handshake not ready
laforest opened this issue · comments
At the time of checking the ack
lines for both reads (in RD0
), do the same for the write port: in WR0
, select the correct ack
line and use it to annul an instruction before it reaches the Controller and ALU.
Given a completed #21, this should implement in a similar way, and can just tack on to the existing muxing and annulling circuitry.
