Abstract
A bus for transferring data is disclosed wherein the bus supports asynchronous, synchronous and high speed synchronous data transfers of varying size. The bus includes a master component for controlling data transfers with one or more slave components attached to the bus. Each data transfer is either received or supplied by the master via a set of data lines common to each slave component. Further, there are different control lines between the master and the slave components depending on the protocol(s) supported by each of the slaves. In particular, a slave supporting a high speed synchronous protocol is connected to the master by four control lines dedicated to providing control signals for implementing a high speed synchronous protocol handshake. Further, a fifth such control line is used to select a slave for a high speed synchronous data transfer when there is a plurality of high speed synchronous slaves.
