Method and apparatus for managing data transfers between peripheral devices by encoding a start code in a line of data to initiate the data transfers

摘要

A method and apparatus for ensuring that information transfers from memory to a peripheral device are complete prior to the peripheral device executing instructions responsive to the content of the information is described. The method includes identifying lines of data to be written, determining a unique start code to be used for that data, and embedding that start code into that data. When the proper number of lines of data have arrived in peripheral device memory, the pending operation is executed.
