In this paper, we describe a fast and convenient verification methodology for microprocessor using large-size, real application programs as test vectors. The verification environment is based on automatic consistency checking between the golden behavioral reference model and the target HDL model, which are run in an hand-shaking fashion. In conjunction with(More)
In this paper, we propose a 'conforming inverted data store' scheme for reducing the power consumption in memory components. It reduces the power consumption by conforming memory contents to a precharging value of the memory. It selectively stores normal or inverted data so to reduce the total number of accessing bits different from the precharging value.(More)
This paper describes a core-customization process of a CISC processor core for a given application program. It aims at the power reduction in the CISC processor core by fully utilizing the microcode-based control scheme, that is one of the most characterizing features of a CISC processor. The optimization process includes two key techniques, generation of(More)
—In this paper, we propose a scheme for reducing the power consumption of memory components by conforming memory contents to a precharging value. The scheme is oriented to application to single bitline structure of memory. It selectively stores normal or inverted data to reduce the number of bit accesses that have different values from the precharging(More)
Absfrncf-We propose a scheme for expanding switch modules to form a larger switch using the so-called focnl switching obtained by allowing bidirectional connection to the conventional three-stage Clos network switch. The performance of the proposed expansion architecture was compared to that of the conventional three-stage Clos network. We simulated 32x32(More)
