摘要:
A processor comprises first and second operation units (1, 2), a first program memory (3) which contains first microinstructions for controlling the first operation unit and second microinstructions for controlling at least the second operation units, a second program memory (4) which contains microinstructions for controlling the second operation unit, first control means (7) connected to the first program memory for controlling the first operation unit and the second operation unit, and second control means (8) connected to the second program memory for controlling the second operation unit. In a normal mode, all operation units (1, 2) are under control of the first control means (7) and in a multi-program mode, the first operation unit (1) is under control of the first control means (7) and the second operation unit (2) is under control of the second control means (8). These two mode operations are selected in accordance with the microinstructions stored in the first or second program memories (3.4).
摘要:
In an image recording/reproduction method for recording image information on a recording medium by using a computer, a verify mode is set into the OFF state (506) when recording image information on said recording medium. In addition, use as a write or read region a specified region of the recording medium which is greater than or equal to a unitary data size being handled during error correction processing to be performed when writing or reading image information on or out of said recording medium. Additionally, upon reading of image information from the recording medium, any image information that has experienced read errors will never be read again.

摘要:
A parallel data processing system comprising a control means (3-11, a plurality of processing means (3-2) controlled by said control means and adapted to perform parallel data processing, memory means provided correspondingly to said processing means and adapted to store data for corresponding processing means, and ring bus means (3-3) connecting said memory means in a ring configuration so that data is shifted along the ring bus. Each of the processing means performs data processing based on data transferred to the corresponding memory means.
摘要:
A multiprocessor system includes processor units (20) connected physically in one-dimensional fashion along a ring bus (1) located at the node of each processor element (3) and associated local memory (2), so that various system operating modes are possible. The ring bus is used for inter-processor data transfer, with the address and read/write signals to each local memory being supplied from the processor element (by the program). Synchronization between the data flow on the ring bus and the processor operation is made automatic by the innovated method of inter-processor connection, which includes flag latches in the ring bus, whereby the system accomplishes extremely high-speed processing.
