ABSTRACT:
In a data processing system having a slave computer connecting to a host central processing unit and a host main memory, the slave computer has no internal random access memory and includes an arithmetic logic operating means. The arithmetic logic operating means calculates an address of the host main memory. A DMA interface directly makes an access to the host main memory to fetch operand data into the slave computer. The arithmetic logic operating means computes the operand data under control of a microprogram control section and directly loads the computed result to the host main memory through the DMA interface.
