| - | ProtoFlex is an FPGA-accelerated hybrid functional simulatordesigned to advance large-scale multiprocessor hardware and software research. ProtoFlex provides first-class support for full-system fidelity–i.e., the ability to run stock commercial operating systems with I/O support. This is accomplished without undue effort by leveraging a hybrid emulation technique called transplanting. Our transplant technology uses FPGAs to dynamically accelerate only common-case behaviors while relegating infrequent, complex behaviors (e.g., I/O devices) to software simulation. By working in concert with existing full-system simulators, transplanting avoids the costly and unnecessary construction of the entire target system in FPGA. At present, we are targeting SPARCV9 and x86 platforms. | + | ProtoFlex is an FPGA-accelerated hybrid functional simulator designed to advance large-scale multiprocessor hardware and software research.
