ABSTRACT:
A high performance digital signal processor includes a memory for storing instructions and operands for digital signal computations and a core processor connected to the memory. The memory includes first, second and third memory banks connected to the core processor by first, second and third data and address buses, respectively. The core processor includes a program sequencer and first and second computation blocks for performing first and second subsets, respectively, of the digital signal computations. Single, dual or quad data words of 32 bits each may be accessed in each of the memory banks during each clock cycle. The multiple data words may be transferred to one or both of the first and second computation blocks.
