  • Processor with multiple microprogrammed processing units
    Patent number: 5408623
    Abstract: A data processing system having processors with large instruction sets comprises a plurality of microprogrammed execution units (EAD, BDP, FPP), which communicate with one another and with a memory (MU) by way of a cache memory (CA). One of the units is an addressing unit (EAD). A second unit is a binary and a decimal calculation unit (BOP). A third unit is a floating point calculation unit (FPP). To permit the units to function autonomously, each unit includes its own command block and synchronizing means to authorize or interrupt the execution of the microprogram defined by the instruction in progress in each unit.
