ABSTRACT:
An interruptible microprogram sequencing unit (MSU) for providing a sequence of microinstruction addresses to a control memory containing microinstructions for the operation of a microprogrammed apparatus. The MSU includes an address output for providing microinstruction addresses to the control memory, an address bus connected to the address output such that a plurality of microinstruction addresses applied to the address bus are sequentially provided to the address output, means connected to the address bus for applying the plurality of microinstruction addresses to the address bus, an interrupt return register operably connected to the address bus for receiving a microinstruction address from the address bus and storing the received microinstruction address, and means connected to the address bus for interrupting the sequence of microinstruction addresses and effecting storage of a microinstruction address on the address bus in the interrupt return register.
