Abstract

PURPOSE:To prevent the degradation in processing speed and processing capability of an information processor even in case of a large quantity of processing data by performing conversion of bit positions of data and logic operation by hardware. CONSTITUTION:The titled circuit is provided with a bus interface circuit 1 for connection to a bus 8 of the information processor, a command analyzing circuit 2 which controls the operation of 9 bit string converting circuit 9 by the instruction of a CPU 6, and a conversion table storage RAM 3 where conversion data as a command group for bit string conversion is stored. Further the circuit is provided with a conversion table analyzing circuit 4 which analyzes the contents of the conversion table and sends an address signal, which designates an address of a bit string to be converted, and a memory control signal for the control of a memory 7 to control the bit converting operation and a bit converting circuit 5 which performs the bit converting operation by the control of the conversion table analyzing circuit 4. Conversion of bit positions of data and logic operations are performed by hardware independent of the CPU 6. Thus, the degradation in processing speed and processing capability of the information processor is prevented.
