Abstract
A disk controller includes memory that is accessible by both a microprocessor and an operation logic. Information needed by the operation logic to perform an operation is stored in a task description block in memory by the microprocessor, and a pointer to the task description block is added to a task description block queue. The operation logic is then able to access task description blocks, based on the pointers in the queue, at will and perform the corresponding operations.
