• 
  [Electronics]
  A machine-code instruction that controls the operation of a computer directly (i.e., it is a “wired-in” instruction, or one set by DIP switches, independent of programs loaded into the machine).
  

• The time in which one microinstruction is executed . in general, several microcycles are required to execute one instruction
• A field from the microinstruction is used for jumps, or other logic.
• This is very similar to the way CPUs with microcode execute one microinstruction per cycle.
• The simple decoders generated one microinstruction every cycle and the complex decoder could generate up to four.
• A counter is used for the typical case, that the next microinstruction is the one to execute.
• Consequently, each horizontal microinstruction is wider ( contains more bits ) and occupies more storage space than a vertical microinstruction.
• Consequently, each horizontal microinstruction is wider ( contains more bits ) and occupies more storage space than a vertical microinstruction.
• Usually the addresses are generated by some combination of a counter, a field from a microinstruction, and some subset of the instruction register.
• The Geometry Engine uses a 195-bit microinstruction, which is compressed in order to reduce size and bandwidth usage in return for slightly less performance.
• It contained a 16-bit 29116 microprocessor clocked at 10 MHz with a 10 KB memory containing 2, 048 40-bit words of microinstruction memory.
