ABSTRACT:
An interface between a host and a slave device having a latency greater than the latency of the host is disclosed. The interface includes a register and a state machine. The state machine provides data to the host from any address in the slave in two host read cycles. The state machine receives a first request from the host for data stored at a first address in the slave at a first time. The state machine stores the data returned from the slave in response to the first request in the register at a second time. The state machine receives a second request from the host for data stored at a second address in the slave at a third time. The state machine provides the data specified in the first request to the host at a fourth time. The state machine is additionally adapted to provide data to the host from a second address in the slave in one read cycle.
