Abstract

The MCU (Microprogrammed Control Unit) is a high-speed, executive, input-output (I/O) processor and interrupt handler for the NRL Signal Processing Element (SPE), a part of the All Applications Digital Computer (AADC). It is the job of the MCU to supervise all SPE elements and to direct and initiate all data transfers between these elements. Referring to Fig. 1, one can see that the MCU directs the SPAU (Signal Processing Arithmetic Unit) and the CC's (Channel Controllers) via the Z bus, and communicates with up to 8 buffer memories over its two channels to the SCU (Storage Control Unit). To better understand the importance of the MCU, one needs to briefly examine the functions of the other SPE elements.
