This chapter provides an overview of configurable computing and its current and future trends. Configurable computing, or reconfigurable computing, refers to the use of configurable hardware for computing purposes. The recent interest in configurable computing is mainly due to the rapid advance in technology of field-programmable gate arrays (FPGAs), devices containing a collection of programmable elements connected together by a network that may also be programmable by users. In short, FPGAs combine the flexibility of software with a performance approaching that of custom-developed hardware. FPGAs is the favored choice in implementing glue logic, experimental systems, and hardware prototypes because of advantages such as short turnaround time, user reconfigurability, and low development costs. However, there are area and time overheads for providing configurable logic, configurable storage, and configurable routing resources. This chapter adopts a broad interpretation for the term run-time reconfigurability: it includes devices that support only complete reconfiguration by the user and those that can be partially reconfigured at run time. This chapter further outlines an approach to exploit run-time reconfigurability. © 2005 Copyright © 2005 Elsevier Inc. All rights reserved.

Rissa T, Cheung PYK, Luk W, 2005, Mixed abstraction execution for the SoftSONIC virtual hardware platform, Pages: 976-979, ISSN: 1548-3746

This paper presents a systematic approach for mixed abstraction execution in the SoftSONIC virtual hardware platform. In mixed abstraction execution different levels of abstraction, for example clockless coarse granularity Transaction Level Modelling (TLM) and clocked Register Transfer Level (RTL) models can be co-simulated. When combining 10 Hz to 1 kHz-range RTL model of component under development with 100 kHz to 10 MHz-range TLM model of rest of the system, the full system simulates close to the speed of one RTL component alone. By verifying the components in full system simulation, error-prone and tedious per-component testbench generation can be avoided. Mixed abstraction execution also gives the possibility of gradual refinement and parallel development and verification of system components. These aspects can reduce the overall design time, as we show in this paper with the development of a real-time JPEG 2000 hardware encoder. © 2005 IEEE.

This chapter presents the effects of polynomial degrees on the hierarchical segmentation method (HSM) for approximating functions. HSM uses a novel hierarchy of uniform segments and segments with size varying by powers of two. This scheme enables us to approximate non-linear regions of a function particularly well. The degrees of the polynomials play an important role when approximating functions with HSM: the higher the degree, the fewer segments are needed to meet the same error requirement. However, higher degree polynomials require more multipliers and adders, leading to higher circuit complexity and more delay. Hence, there is a tradeoff between table size, circuit complexity and delay. We explore these tradeoffs with four functions:, x log(x), a high order rational function and cos(πx/2). We present results for polynomials up to the fifth order for various operand sizes between 8 and 24 bits. © 2005 Springer.
