Software Architectures for Real-time Embedded Applications for Broadcasting

Abstract. The paper discusses a choice of appropriate software architecture with regards to the specifications of embedded applications as information systems particularly used in area of radio and television broadcast audio program processing. The main requirement of mentioned embedded systems is an extremely good real-time response and minimized latency between input signal and output signal after processing. The requirements imposed to software architecture from the viewpoint of methods and algorithms which process the signal are in our case subjected to the minimal input-output latency requirement and specifics of hardware architecture and data structures used in embedded systems. The software architecture components and options are discussed and reviewed with their assets and limitations
