Abstract: A programmable external storage control apparatus is provided which requires minimum intervention of a microprocessor and has more extendibility and flexibility. It includes a buffer (16) which stores a data transfer control program in addition to data to be transferred between a host (10) and an external storage (14), a controller (18) which reads from the buffer (16) and executes the data transfer control programs, and a microprocessor (20) which starts reading of the program from the buffer (16) to the controller (18) in response to a command from the host (10). The controller (18) controls data transfer between the host and the external storage independently of the microprocessor (20) while the microprocessor (20) may execute other jobs.

Abstract: PURPOSE: To provide a programmable storage controller which can minimize the intervention of a microprocessor and also excels in both extendibility and flexibility. CONSTITUTION: This controller includes a buffer 16 which stores a data transfer control program in addition to the data that are transferred between a host 10 and an external storage 14, a controller 18 which reads the data transfer control program out of the buffer 16 and carries it out, and a microprocessor 20 which starts to read the program out of the buffer 16 and to send it to the controller 18 in response to the command given from the host 10. The controller 18 controls the data that are transferred between the host 10 and the storage 14 independently of the microporcessor 20. Meanwhile, the processor 20 can carry out other jobs.
