Abstract
A data processing system ( ) is provided with a digital signal processor (DSP) ( ) that has an instruction set architecture (ISA) that is optimized for intensive numeric algorithm processing. The DSP has dual load/store units (.D , .D ) connected to dual memory ports (T , T ) in a level one data cache memory controller ( ). The DSP can execute two aligned data transfers each having a length of one byte, two bytes, four bytes, or eight bytes in parallel by executing two load/store instructions. The DSP can also execute a single non-aligned data transfer having a length of four bytes or eight bytes by executing a non-aligned load/store instruction that utilizes both memory target ports.
