A circuit in which the clock is assumed to be distributed periodically to each individual register though not necessarily to all registers simultaneously, called a semi-synchronous circuit, is expected to achieve higher frequency or a smaller clock tree compared with an ordinary synchronous circuit, called a complete-synchronous circuit. In this paper, we propose a circuit design method that realizes a semi-synchronous circuit with higher frequency by modifying the clock tree of a complete-synchronous circuit. We confirm that the proposed method is easy to incorporate with current practical design environment by designing a four stage pipelined processor compatible with MIPS operation code. The obtained processor circuit is the first semi-synchronous circuit designed systematically with theoretical background.
