ABSTRACT:
A method for providing bounded latency in a real-time data processing system is disclosed. Initially, a batch size is selected. Then, a worst case real time bandwidth (WCRTB) and a bytes-in-batch (BIB) are assigned. Next, a worst case data movement time (WCDMT) is calculated by using the WCRTB and BIB. A processor available cycles per second (PACPS), a processor cycle per sample to execute a function (K), a batch period (P) and a sample period (T) are then assigned. A required function cycles per second (RFCPS) is calculated by using the K and T. Subsequently, a BET is calculated by using the P, RFCPS and PACPS. Finally, BET is maintained to be less than P for ensuring the real-time data processing system to function properly.
