VECTOR PROCESSOR

摘要

PURPOSE:To process at a high speed a DO loop including the multiplex condition decision by erasing a vector instruction to be invalidated within an instruction starting circuit in case the vector mask registers have the same value. CONSTITUTION:The vector instructions read out of a main memory 9 are sorted for data processing by a decoder in an instruction control unit 8. The results of this sorting are stored in registers 1-5. These stored vector instructions and the decoding information on the vector mask registers are sent to a vector instruction starting logical circuit 6. The circuit 6 receives the resource idle information sent from plural resources through a bus 15 and the erasing indication for positive and comprementary mask value using instructions detected by a masking data detecting circuit 7 through buses 16 and 17. Then the vector instruction is assigned to each resource through a bus 18 only when the vector instruction start is significant.
