Abstract
A device for providing data includes a data source, a bus interface, a data buffer, and control logic. The bus interface is coupled to a plurality of control lines of a bus and adapted to receive a read request targeting the data source. The control logic is adapted to determine if the read request requires multiple data phases to complete based on the control lines, and to retrieve at least two data phases of data from the data source and store them in the data buffer in response to the read request requiring multiple data phases to complete. A method for retrieving data includes receiving a read request on a bus. The bus includes a plurality of control lines. It is determined if the read request requires multiple data phases to complete based on the control lines. At least two data phases of data are retrieved from a data source in response to the read request requiring multiple data phases to complete. The at least two data phases of data are stored in a data buffer.
