Abstract
A packet format converter (PFC) that can be programmed to perform any one of a multiple number of different packet format conversions is described. According to one embodiment, the PFC includes a pattern state machine and a pattern memory coupled to the pattern state machine. The pattern memory stores pattern memory data including pointer information. The pointer information is either for writing data to be input into the PFC or reading data to be output by the PFC. The pattern state machine is programmed based on the pattern memory data. Also in one embodiment, the PFC further includes a backpressure control for issuing ready and valid signals for the PFC, wherein the ready signal indicates whether the PFC is ready to accept input data and the valid signal indicates whether the PFC has valid data to output.
