چکیده
This paper presents the INSIDE system that rapidly searches the design space for extensible processors, given area and performance constraints of an embedded application, while minimizing the design turn-around-time. Our system consists Of a ) a methodology to determine which code segments are most suited for implementation a5 a set of extensible instructions, b) a heuristic algorithm to select pre-configured extensible processors as well as extensible instructions (library), and c) an estimation tool which rapidly estimates the performance of an application on a generated extensible processor. By selecting the right combination of a processor core plus extensible instructions, we achieve a performance increase on average of 2 . 0 3 ~ (up to 7x) compared to the base processor core at a minimum hardware overhead of 25% on average.

متن کاملGenerating and evaluating application-specific hardware extensions
Modern platform-based design involves the application-specific extension of embedded processors to fit customer requirements. To accomplish this task, the possibilities offered by recent custom/extensible processors for tuning their instruction set and microarchitecture to the applications of interest have to be exploited. A significant factor often determining the success of this process is th...

Due to an increasing need for flexibility, embedded systems embody more and more programmable processors as their core components. Because of silicon area and power considerations, the corresponding instruction sets are often highly encoded to minimize code size for given performance requirements. This has hampered the development of robust optimizing compilers because the resulting irregular i...
متن کاملPD-XML: extensible markup language for processor description
This paper introduces PD-XML, a meta-language for describing instruction processors in general and with an emphasis on embedded processors, with the specific aim of enabling their rapid prototyping, evaluation and eventual design and implementation. The proposed methodology is based on the extensible markup language XML widely used structured information exchange and collaboration. PDXML allows...
