Abstract
Methods and apparatus are provided for closely coupling a dedicated memory port to a processor core while allowing external components access to the dedicated memory. A processor core such as a processor core on a programmable chip is provided with dedicated read access to a dual ported memory. Write access is arbitrated between processor core write access and read/write access by external components. A dedicated memory port is particularly beneficial in digital signal processing applications.
