Title:
INFORMATION PROCESSOR
Document Type and Number:
Japanese Patent JPH0581118
Kind Code:
A
Abstract:
PURPOSE: To realize an information processor where a specified processing (for example: data inversion) having few advantages in leaving the processing to a hardware part by an ordinary method is executed at high speed.
CONSTITUTION: When data is inverted, CPU 11 defines the hardware part 13 to be validity and also reads data from a memory 12 with the control circuit 20. Read data is inverted in an inverter circuit 22 after being latched in a latching circuit 21 and the inverted data is given to CPU 11 with a buffer circuit 23 and a data bus 14. Thus, the inversion processing of data is realized by the hardware part 13 as one of continuous access operations.
