Abstract
A disk controller that controls data transfer between a storage device and a host system is provided. The disk controller includes logic having a state machine that controls de-assertion of a read gate signal based on sector size and/or whether a data segment is split or non-split. The read gate signal is de-asserted at programmable times, based on data sector size. The state machine interfaces with a register whose settings indicate to the state machine that next time when the state machine starts executing from an idle state it should process a second half of a split sector. The state machine also uses a register that to extend assertion of the read gate signal. It is noteworthy that the read gate signal is controlled on a positive and negative edge of a write clock signal.
