Or1ksim is a generic OpenRISC 1000 architecture simulator capable of emulating OpenRISC based computer systems. Or1ksim provides several unique features: * Free, open source code * High level, fast, architecture simulation that allows early code analysis and system performance evaluation * All major models of OpenCores peripheral and system controller cores supported * Easy addition of new peripheral models * Remote debugging through a network socket with the GNU Debugger (GDB) * Support for different environments (memory configurations and sizes, OR1K processor model, configuration of peripheral devices)
