Abstract
A digital signal processor (DSP) includes a CPU, and a DMA controller. The DMA controller transfers data from a source to a destination as a function of an initialization command from the CPU. The DMA controller has a logic unit that performs filter operations and other arithmetic operations on-the-fly on a data stream transferred therethrough. The filter operations include multiplication by filter coefficients and addition, without processing by the CPU. The DMA controller may have subsets of hardware configurations that can perform different operations that are selectable as a function of the initialization command.
