Abstract
A circuit arrangement reduces the number of interrupts to a DSP required to transfer digital samples between external I/O devices and a data memory, thus allowing the DSP to perform additional sample processing operations. An interrupt accelerator responds to I/O interrupts from an I/O device by pausing the DSP, transferring samples with the data memory, and tracking the number of samples transferred. When a predetermined number of samples have been transferred, the interrupt accelerator interrupts the DSP to perform a block transfer of samples in conjunction with sample processing.
