Abstract
Today��s embedded applications tend to become more complex over time, and they require high performance with small code size and low power consumption. A 16-bit width instruction set architecture is still one of the good solution to satisfy these various requirements. But this architecture has limited instruction bit width, that is, only 16-bit. Limited instruction bit width might introduce more extra instructions which can increase code size and decrease the performance. Therefore, in the our previous work, we proposed a new instruction encoding scheme based on the dynamic implied addressing mode (DIAM) to resolve limited encoding space and side-effect by trimming. Our DIAM-based approach used a special program memory to store extra encoding information. We also suggested a code generation algorithm to fully utilize the DIAM. But this approach has severe weakness when a target application code has lots of large immediate operands. In this paper, we will discuss how to overcome this weakness with new DIAM architecture that called as advanced immediate instructions with DIAM. ? 2015 American Scientific Publishers.
