A magnetoelectronic register file cell for a self-checkpointing microprocessor

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...

Application-Based Analysis of Register File Criticality for Reliability Assessment in Embedded Microprocessors

There is an increasing concern to reduce the cost and overheads during the development of reliable systems. Selective protection of most critical parts of the systems represents a viable solution to obtain a high level of reliability at a fraction of the cost. In particular to design a selective fault mitigation strategy for processor-based systems, it is mandatory to identify and prioritize th...

To Improve Register File Integrity against Soft Errors By using self - Immunity Technique

Continuous shrinking in feature size, increasing power density etc, increase the vulnerability of microprocessors against soft errors even in terrestrial applications. The register file is one of the essential architectural components where soft errors can be very mischievous because errors may rapidly spread from there throughout the whole system. Thus, register files are recognized as one of ...

A Power Aware Cache and Register File Design Space Exploration

A Polymorphic Register File Architecture

Previous vector architectures divided the available register file space in a fixed number of registers of equal sizes. We propose a novel register file organization which allows dynamic creation of a variable number of multidimensional registers of arbitrary sizes the Polymorphic Register File. We have selected Floyd 64x64 as our benchmark. Simulation results suggest a speedup of up to 8X compa...
