Apron: A cellular processor array simulation and hardware design tool

Abstract – We present a software environment for the efficient simulation of cellular processor arrays (CPAs). This software is used to explore algorithms that are designed for CPAs, neuromorphic arrays, multi-layer neural networks and vision chips. The software (APRON) uses a highly optimised core combined with a flexible compiler to provide the user with tools for the prototyping of new array hardware and the emulation of existing devices. We show that software processor arrays can operate at impressive speeds, with high numerical accuracy. APRON can be configured to use additional processing hardware if necessary, and can even be used as the graphical user interface for new or existing CPA systems
