Abstract
An interface circuit for providing an interface with the parallel data bus that transfers information in a multiple of formats. The interface includes a control circuit that receives or sends control signals from or to the parallel bus to regulate the data transfer and to specify one of the plurality of formats. An addressing circuit, connected to the control circuit, is provided for computing addresses for each of the data received or sent according to the specified format. An accessing circuit connected to the bus, control and address circuits is provided to store or retrieve data from or to the bus according to the computed data addresses. This interface provides a means to serialize data when, in one format, the first word of a data transfer is provided on one part of the data bus but, in a second format, the first data word is provided on another part of the data bus.
