concurrency/ C5440 Multiprocessing systems C5610S System busesWe present a hardware design of a multimicroprocessor system with hierarchical bus organization. The organization is multi-level and each bus in the hierarchy is time-shared and memory-coupled. The microprocessor Intel 8085 is used as ...

The CPU030 blends the powerful CPU32+ with on-chip instruction caches and data memory to deliver MC68030 performance with minimal degradation due to slow external memory systems. A system integration module incorporates the external bus interface and many of the smaller circuits that typically ...
The 750CL's three-state cache-coherency protocol (MEI) supports the modified, exclusive and invalid states, a compatible subset of the MESI (modified/exclusive/shared/invalid) four-state protocol, and it operates coherently in systems with four-state caches. 750CL supports single-beat and burst...
Similarly, the 601 supports split-bus transactions for systems with multiple potential bus masters—one device can have mastership of the address bus while another has mastership of the data bus. Allowing multiple bus transactions to occur simultaneously increases the available bus bandwidth for other ...
can pass data around internally with a full 32-bit register size; for communications with the outside world, however, the chip is restricted to a 16-bit-wide data path. This design enabled a systems designer to build a lower-cost motherboard with a 16-bit bus design and still maintain ...

This invention relates to microprocessor systems and more specifically to electronic calculators having the capability of solving higher order or complex mathematic problems. It should become evident, moreover, that my invention has utility in other applications making use of microprocessor technology, such...
