摘要： A computer memory system is disclosed with an input/output circuitry capable of separating the load separating the load capacitance of an output circuit of a semiconductor memory connected to a memory bus from the memory bus. In order to separate the load capacitance of a semiconductor memory connected to a memory bus signal line, a Schottky diode is arranged between the semiconductor memory and the memory bus line, and a voltage control circuit is provided to control whether a reverse bias voltage is applied to the Schottky diode. The speed of signal transmission does not decrease even when a large number of semiconductor memories are connected to the memory bus since the load capacitance of the semiconductor memories is separated from the bus. Therefore, it is possible to construct a high speed and large capacity memory system.

While one or both of said electric buses have been driven (ON mode) by the nodes connected thereto, an optical output has been continuously produced from the buses that are being driven to said optical fibers, and while light has been inputted from said optical fibers, the modes of said buses are not observed, but an electric output is produced to the electric bus of the side to which light is inputted to drive the bus. The optical bus-bridging device changes the mode of the electric bus when the optical fiber does not change within a predetermined period of time after the optical bus-bridging device has outputted a signal to the optical fiber.

摘要： To provide a large scale multiprocessor system capable of executing an area limited cache coherency control implementing a high speed operation while substantially reducing the amount of processor-to-processor communications there is provided a translation lookaside buffer which retains cache coherency attribute information defining a limitable cache coherent area to maintain data consistency among caches, and a processor memory interface unit includes a cache coherency control which identifies whether cache coherency is required only within a particular cluster of processors or is required for every one of the cache memories in every one of the clusters throughout the system, on the basis of the contents of the cache coherency attribute information. Further, in another version of large scale multiprocessor system, each cluster may be provided with an export directory which registers an identifier of data whose copy is cached in cache memories in other clusters. Thereby, latency in cache coherency procedures can be reduced greatly, since a cache coherent area can be limited in dependence on various characteristics of data. Further, it is also possible to greatly reduce inter-cluster communication quantities, since it is no longer necessary to broadcast to all processors in the system upon every occasion of a memory read/write.

摘要： A multiplication, division and square root extraction apparatus which calculates the solutions to addition, division and square root extraction functions by approximation using iteration has a multiplier, an adder-subtracter and a shifter of prescribed bit width connected to a bus. Iteration is conducted by inputting the output of the multiplier to the adder-subtracter or the shifter and returning the result to the input of the multiplier via the bus. A shifter and an arithmetic and logic unit connected to a second bus connected to the aforesaid bus via a switch have a greater bit width than the prescribed bit width and are used for large scale calculations, thus preventing a reduction in processing speed.
