ADSP-2159x/ADSP-SC591/592/594 SHARC+ Processor Hardware Reference
■The ADSP-SC591/2/4 processor includes an Arm® Cortex-A5® core. The Arm Cortex-A5 processor is the smallest,lowest cost and lowest power Armv7 application processor. The A5 sub-system in the ADSP-SC591/2/4 processor includes a Floating-Point Unit, NEON Media Processing Engine, Generic Interrupt Controller and a Level 2 Cache Controller. The A5 also includes support for a L1-Cache sub-system and a full-fledged Memory Management Unit.The A5 implements the Armv7 architecture and runs 32-bit Arm instructions, 16-bit and 32-bit Thumb instructions, and 8-bit Java byte-codes in Jazelle state.
■This document describes the Arm Cortex-A5 core and memory architecture used on the ADSP-SC591/2/4 process-or, but does not provide detailed programming information for the Arm processor.
