Abstract
Memory access in a digital signal processing system is described. In one example, the digital signal processing system comprises a multi-port memory that is constructed from a memory interface connected to a number of single-port memory devices. The memory interface provides access ports that processors can use to access data stored on the single-port memory devices using a single address space. A processor can be connected to several access ports, and use these to request access to data at several different memory addresses at the same time. The digital signal processing system is configured such that the total number of single-port memory devices connected to the memory interface is a prime number greater than or equal to three. Because a prime number of memory devices are used, the likelihood of the data for the different memory addresses being on the same single-port memory device is minimised, increasing memory access speed.
