Abstract
A command queuing engine in a target controller ASIC automatically detects sequential commands received from an initiator and generates a linked list of data transfer descriptors for the sequential commands. The data transfer descriptors are automatically processed by the command queuing engine to reduce command overhead from interrupt processing by a microprocessor in the target controller, thereby improving the performance of the target controller.
