Microprocessors have been used in wide-ranged applications. During the execution of instructions, instruction decoding is a major task for identifying instructions and generating control signals for data-paths. By exploiting program behaviors, we propose a novel instruction-decoding approach for power minimization. Using the proposed instruction-decoding(More)
Significant advances in VLSI process technology have scaled the feature size down. One effect of this scaling down is that coupling capacitances have grown reciprocal in the square of the scaling factor. This crosstalk effect will not only increase the power consumption but also lengthen the propagation delay. Since the data sequences on an instruction bus(More)
This paper presents a novel power-driven multiplication instruction-set design method for application-specific instruction-set processors (ASIPs). Based on a dual-and-configurable-multiplier structure, our proposed method devises a multiplication instruction set for low-power ASIPs. Our method exploits the execution sequences of multiplication instructions(More)
Over the years, many design methodologies/tools and layout architectures have been developed for datapath-oriented designs. One commonly used approach for high-speed datapath designs is the full-custom design method targeted to bit-sliced or bit-alignment layout architectures. Using this approach, designers can fully exploit design properties, such as(More)
A modern special-purpose processor (e.g., for image and graphical applications) usually contains a set of instructions supporting complex multiply-operations. These instructions perform a variety of multiply-operations with various data bitwidths and concurrent-execution requirements. For instance, such an instruction set may include instructions to perform(More)
Significant advances in very large-scale integration process technology have scaled the feature size down. One effect of this scaling down is that coupling capacitances have grown reciprocal in the square of the scaling factor. This crosstalk effect will not only increase the power consumption but also lengthen the propagation delay. Since the data(More)
