MAJC combines multiprocessing, multithreading features eetimes.com "Multithreading will be the next hot topic in microprocessor architectures," said Marc Tremblay, chief architect for the MAJC project. "Most chips today that are attempting to incorporate parallel processing are doing it at the instruction level, but we are focusing on the thread level, which delivers much more performance." Multithreading involves breaking down the various tasks in one or more applications into several threads and scheduling them for the most efficient use of the microprocessor's computing power. When one task results in a cache-miss, the processor will have an idle period while the system imports data from the main memory. Multithreading allows the CPU to work on a different thread during that down time. "The overall throughput is much higher," said Tremblay. "While the first thread will finish at about the same time as it would on a traditional CPU, in this case the same processor can complete several other things at the same time."
