Transfer progress alert module

Abstract

A Transfer Progress Alert Module and a method for optimizing processing of a data transfer load, in a data communication system is provided. The data transfer load is divided in individual data blocks. The device and method simultaneously perform pipelined operations on different individual data blocks, thus optimizing the overlap of pipelined operations. The method includes initializing the transfer by selecting a pre-defined individual data block size and determining a key for selecting and monitoring transfers with transfer addresses within a pre-determined address region. The method then continuously repeats following steps until all monitored individual data blocks from the data transfer load are processed. First, the incoming individual data blocks are transferred on a bus between a peripheral device and a memory, and the Transfer Progress Alert module is used for monitoring the individual data blocks having transfer addresses determined to belong in the pre-determined address region. The TPA module is used to determine when each monitored transferred individual data block is ready for a post-processing operation, at least one post-processing operation is performed on the data, and the processed data is transferred to a peripheral device. The method and device may also be adapted for performing an error detection operation on the monitored individual data blocks transferred on the bus, for ascertaining the integrity of the transferred data.
