From a92a5d0dce5b02fa34792e313b5fe3d7d317b17b Mon Sep 17 00:00:00 2001 From: Mischa Jonker Date: Thu, 18 Apr 2013 11:40:39 +0200 Subject: ARC: Add support for nSIM OSCI System C model This adds support for an ARC Virtual Platform. This platform is based on the System C standard promoted by the OSCI (Open System C Initiative) and uses nSIM to simulate the ARC CPU core itself. Users can build a virtual SoC by combining System C models of peripherals and CPU cores.
