Unencoded micro-instructions

  • One bit is required for each control signal; so number of bits needed in a micro-instruction is high.
  • It represents a detailed hardware view, as control signal need can be concluded.
  • Since every one of the control signals can be controlled particularlyso these micro-instructions are difficult to program. Though concurrency can be used easily.
  • Almost no control logic is required to decode the instruction as there is one to one mapping of control signals to a bit of micro-instruction. So execution of micro-instruction and henceforth micro-program is faster.
  • Unencoded micro-instruction purposes at optimising performance of a machine.
