Abstract:

The single-thread performance of a CPU is an essential factor in a computer system. However, increasing the processing width of a CPU to improve performance often results in a super-linear enlargement of the circuit area and, consequently, a massive increase in power consumption. In this paper, we present an out-of-order superscalar processor based on a new architecture, STRAIGHT, which overcomes the circuit area and power consumption problems. We have designed and evaluated the first real processor chip based on the STRAIGHT architecture. The processor chip was fabricated using 28nm CMOS technology, and we confirmed that it could correctly execute real programs. We evaluated its performance, circuit area, and power consumption, and as a result, demonstrated that a large processing width can be achieved in a small area using the new STRAIGHT architecture.
