Abstract :
Multichannel video usecases put considerable resource demands on the processing system. Software designed for single channel when extended to multichannel often does not exploit the capabilities of the system fully and limits the number of channels that can be processed simultaneously. In this paper, we discuss the performance constraints observed in an asynchronous multiprocessor system when extending a single channel codec software solution to a multichannel usecase. This is followed by a discussion on building a multichannel codec solution using the existing single channel framework by exploiting bunch submission and parallelizing the operations of different processing cores to maximize the system resource utilization. Upto 30% channel density gains are observed when migrating from the single channel to multichannel solution.
