ABSTRACT:
Apparatus for evaluating the performance of DMA-based algorithmic tasks on a target multi-core processing system includes a memory and at least one processor coupled to the memory. The processor is operative: to input a template for a specified task, the template including DMA-related parameters specifying DMA operations and computational operations to be performed; to evaluate performance for the specified task by running a benchmark on the target multi-core processing system, the benchmark being operative to generate data access patterns using DMA operations and invoking prescribed computation routines as specified by the input template; and to provide results of the benchmark indicative of a measure of performance of the specified task corresponding to the target multi-core processing system.
