摘要： PROBLEM TO BE SOLVED: To transfer data with wide data width by using a narrow data transfer path for data and a small number of signal lines for management. SOLUTION: An encoder A stores the high-order and low-order parts of (n)th data which are already transferred from a vector processor to a buffer, and a comparing circuit r1 compares the high-order and low-order parts of the data in the buffer with the high-order and low-order parts of (n+1)th data to be transferred; and a comparison information generating circuit r2 generates comparison information (C-1, C-2) according to the comparison result and a selector r3 selects and transfers only the high-order part, only the low-order part, or the high order part and low-order part of the (n+1)th data to a decoder in order according to the comparison information. The decoder B stores the high-order and low-order parts fo the (n)th data which are already transferred in the buffer, updates or holds the data in the buffer with the high-order part, low-order part, or both the parts of the data of the (n+1)th data transferred according to the comparison information, and then outputs the data in the buffer according to the comparison information.

摘要： PROBLEM TO BE SOLVED: To shorten set time by directly performing the set of scalar data to a scalar register at a vector processor corresponding to a vector instruction. SOLUTION: As a pair of vector instructions, a VLI instruction for setting immediate value data to the low-order 32 bits of the scalar register and a VLIS instruction for setting immediate value data to the high-order 32 bits of the scalar register are prepared, these instructions are composed of OP codes, scalar register numbers to be set and immediate data and by decoding the instructions, the immediate value data are set to the low-order side of register 2371 and the high-order side of a register 2372 at a data control circuit. When executing the instruction, in the case of VLI instruction, the data in the register 2371 are selected and these data are written in the scalar register to be set by a selection circuit. In the case of VLIS instruction, the data in the register 2372 are selected and the data are written in the scalar register to be set by the selection circuit but only the high-order part of data is written corresponding to the designation of a set signal control circuit.

摘要： PURPOSE: To improve the throughput of memory access processing from a vector processor and actualize efficient synchronous processing of common data as to the computer system which uses a buffer storage to transfer the common data between processors. CONSTITUTION: The computer system having the communication buffer storage which holds a copy of data including operand data of a specific scalar instruction shared by scalar processors 10 and 11 in block units is so constituted that the communication buffer storage holds even a copy of data including input/ output control information shared by the scalar processors 10 and 11 and an input/output processor 12 in block units. Further, whether or not each block in the communication buffer storage includes a copy of the operand data of the specific scalar instruction is discriminated and a block which does not include the copy is preferentially replaced.
