ABSTRACT

Chip-multiprocessors are quickly gaining momentum and becoming popular in all areas of computational tasks,however the success of chip-multiprocessors depends on addressing the difficuly in the development of multithreaded applications to overcome this difficulty it is necessary to develop new chip-multiprocessors with advanced programming models presently various architectures relies on software simulators which are too show. this paper present an atternative to simulation by designing platforms based on FPGAs for chip- multiprocessors and its application in multithreaded programe the first prototype for chip-multiprocessors,ATLAS with hardware support for transactional memory a technology aiming to simplify parallel programming is presented.ATLAS included 8 embedded power pc cores that access coherent shared memory in a transactional manner.ATLAS uses the BEE2 multi-FPGA board to provide a system with 8 powerPC cores that run at 100MHz and runs linux...ATLAS provides significant benefits for chip multiprocessoer research such as 100x performance improvement over a software simulator and good visibility that help swith software tuning and architectural improvements. in addition to presenting and evaluating ATLAS,we share our observation about building a FPGA-based framework for chip-multiprocessors research.overall the ATLAS prototype provides an excellent framework for further research on the software and hardware techniques necessary to deliver on the potential of transactional memory.
