[ARM-PowerPC-ColdFire-MIPS] simulator

Description: 开源的基于SystemC的模拟器，可以模拟ARM CPU, Cache, DDR，NOR, NAND, 时序和功耗均可以正确模拟。-This simulator is a cycle-accurate system-level energy and timing simulator. Developed by Embedded Low-Power Laboratory, Seoul National University. The simulator’s underlying kernel is OSCI SystemC 2.2.0. All of the hardware modules satisfies the OSCI standards. The simulator is composed of a CPU, cache, and memory components including DDR SDRAM, MLC NOR Flash, MLC NAND Flash, SRAM. Each memory components have it’s own memory model, which enables cycle-accurate power consumption estimation of the devices. Master and slave SystemC IPs are connected through AMBA AHB CLI (Cycle-Level Interface). You will get energy trace files for each memory devices. You will get cycle-accurate performance evaluation results CPU cycle counts information, and cache hit/miss ratio on console. Also, you can get trace files for memory devices. The simulator exhibits performance over 500 K instructions/sec, which is fairly high for a cycle-accurate system-level simulator. The simulator’s source co
