摘要: A programmable external storage control apparatus, including a buffer for temporarily storing data to be transferred between a host and an external storage, which stores a program for controlling data transfer between the host and the external storage and controls the data transfer between the host and the external storage by reading the data transfer control program from the buffer and executing it. The apparatus further includes a microprocessor that responds to a command from the host by starting the control of the data transfer by reading the data transfer control program. The microprocessor includes a memory for storing the data transfer control program in addition to other programs to be executed by the microprocessor. The microprocessor loads the data transfer control program from the memory into the buffer at the time of initialization. This allows the microprocessor to do other jobs such as servo control while the data transfer control program is executed.
