An Expandable Protocol Processor Architecture

چکیده
BACKGROUND The design of modern data processing hardware for deeply embedded systems like cellular telephones is facing great demands because of the decreasing times-to-market and the increasing demands for performance. This is especially true in third generation cellular phones in which the convergence of traditional telephony and modern multimedia applications makes the emergence of small and efficient hand-held communication devices possible. In order to meet increased performance requirements and to achieve shorter development times new system design technologies like System-on-Chip and ASIP have arisen.

متن کاملUltra-Low-Energy DSP Processor Design for Many-Core Parallel Applications
Background and Objectives: Digital signal processors are widely used in energy constrained applications in which battery lifetime is a critical concern. Accordingly, designing ultra-low-energy processors is a major concern. In this work and in the first step, we propose a sub-threshold DSP processor. Methods: As our baseline architecture, we use a modified version of an existing ultra-low-power...
متن کاملUML-driven TTA-based protocol processor design
A protocol processor is a programmable processor specifically designed to deal efficiently with protocols. The challenge in designing protocol processors is finding an architecture that is a good compromise between a general purpose processor and a custom, protocol-specific processor. We describe a methodology in which we design both a processor and a program for a network processing applicatio...
