Energy efficient, small footprint, 32 bit microcontroller core

Overview

The APS3R is a fully 32 bit general purpose CPU designed specifically to meet the needs of embedded systems.

The APS3R is a 32 bit core with 4 GB address space and a Havard architecture. The instructions are 16 bits in length, with a 16 bit extension when needed (no mode switches necessary) giving excellent code density. The pipeline features out-of-order execution enabling nearly all instructions to execute in a single cycle, including loads and stores. Interrupts are fully vectored and the architecture ensures a minimum of software overhead in task switches. The processor was designed to execute high level languages, notably C, with ease. The software application can be entirely realised in C, interrupt routines included. The entire GNU GCC toolsuite has been ported to this architecture.
