Risc Evolution – Radical Chip Multithreading

David Yen an executive vice president at Sun Microsystems writes in cnet about te next wave of RISC processors. Due to declines in clock frequency, increases in Memory access and power budgets. It is now necessary to reassess the RISC architecture.
At Sun, they’ve termed this brave new future of RISC processor design radical chip multithreading (CMT). Radical CMT processors are designs crafted from the ground up to employ available resources as efficiently as possible in pursuit of their throughput goal. We’re not talking about executing two to four threads in parallel, but 30 or more threads simultaneously.
