    摘要: A multiprocessor system having the capability of increasing the speed of a bus clock while retaining high reliability and fault tolerant performance as well as utilizing the current operating system resources. The multiprocessor system is made up of a plurality of processor modules connected together through a duplicated system bus. The duplicated system bus is divided into a plurality of segments, and these segments are coupled together by at least one bus extender mechanism. The multiprocessor system is also provided with first notification means which is provided between bus control mechanisms for controlling the states of physical buses and the bus extender mechanism, and the bus control mechanisms and the bus extender mechanism are mutually notified of the state of each mechanism through the first notification means.

    摘要: A data width conversion apparatus has a buffer for storing output-incomplete partial data of input data received in the past and a block shifter for combining the output-incomplete partial data stored in said buffer with new input data. In the combined data by the block shifter, a portion of a fixed data width is outputted in form of an output data, and data less than the fixed data width or data exceeding the fixed data width is stored in the buffer so as to be combined with the successive input data.
