ABSTRACT:
According to the invention, a microprocessor computing system comprises at least one data processing device and at least one group of execution control elements; said group constitutes a control level and includes at least one microprogram control device which is a group of first-order control elements. The data processing device incorporates a microinstruction register for holding microinstruction codes, a microoperation decoder, a general-purpose register unit for holding operands, an arithmetic/logic unit, a temporary result storage register, a result status register, and at least one data exchange unit having a multichannel communication line to provide for data exchange between other sources and destinations. The microprogram control device producing parallel microinstruction codes incorporates at least one input register, a programmable address unit, a microinstruction storage unit, a feedback register, a microinstruction register, and an output driver unit.
Each data processing device and each microprogram control device as well, comprise an internal operating cycle generator to generate clock signals of the internal operating cycle, which are used to control data sequencing in the related device, all said internal operating cycle generators being linked through at least one clock signal bus.
