A Single-Phase Register File with Complementary Pass-Transistor Adiabatic Logic

This paper introduces an adiabatic register file based on two-phase CPAL (Complementary Pass-Transistor Adiabatic Logic circuits) with power-gating scheme, which can operate on a single-phase power clock. A 32×32 single-phase adiabatic register file with power-gating scheme has been implemented with TSMC 0.18μm CMOS technology. All the circuits except for the storage cells employ two-phase CPAL...

A three dimensional register file for superscalar processors

The register file is a key datapath component of a superscalar microprocessor. Its access time is critical since it can impact cycle time. Its size can easily become a problem: superscalar microprocessors have a large number of ports (typically 10 for a three-scalar machine) and the size is quadratic in the number of ports. The “3-D Register File’” uses the area inherently consumed by the metal...

Saving Register-File Leakage Power by Monitoring Instruction Sequence in ROB

Modern portable or embedded systems support more and more complex applications. These applications make embedded devices require not only low powerconsumption, but also high computing performance. To enhance performance while hold energy constraints, some high-end embedded processors adopt conventional features to exploit instruction-level parallelism and increase clock rates. The reorder buffe...

An Experimental Investigation of Enclosure’s Effect on Noise Reduction in Portable Generators (Technical Note)

The portable generators are the main means of compensating the shortage of national electricity power as in Iraq. However, their noise causes a huge disturbance, uncomforting and loss of concentration of the nearby resident. This problem requires a solution because most shops and residential houses use generators. Covering method is a simple and relatively low cost one for reduction of generato...
