Prediction of number of data words transferred and the cycle at which data is available

摘要: A microprogrammed data processing system includes a cache memory, decimal unit and an execution unit. The receives operands from strips the non-decimal digit information operands, assembles 4-bit digits operand into words containing maximum of 8 for transfer to processes in accordance with numeric instruction. throughput is increased when short which contain 15 or less by apparatus detects determines number memory cycles between cycle first word received on assembled transferred processing.
