Intel in 1988 developed the first NOR flash technology, completely changed the original from EPROM and EEPROM dominated situation. Then, in 1989, Toshiba made a NAND flash structure, emphasis on reducing the cost per bit, higher performance, and as the disk can easily upgrade through the interface. But after more than a decade later, there is still a considerable number of hardware engineers distinguish NOR and NAND flash memory. Platform: |

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.
