Abstract

PURPOSE:To obtain the signal processing processor which is easy for digital filter processing, by incorporating parallel multipliers. CONSTITUTION:The simultaneous setting of multiplicand and multiplier of a multiplier and the accumulation of the result of multiplication can be made within one step. Further, the multiplier and multiplicand can be set from the data memory of readout and write-in enable and from read only memories of the mixture. Further, by directly connecting the accumulation register which can be used as two double length precision registers and also as the operation register having independent real and imaginary parts, to the output of the multiplier, the one multiplier and accumulation for the integration sum required for the operation of circulation type filter, non-circulation type filter and FET can be executed with one instruction.
