چکیده
In this paper parallel-ism on che algorithmic, architectural , and arithmetic levels is exploited in the design of a Residue Number System (RNS) based archite:;ture. The architecture is basecl on modulo processors. Each modulo processor is implemented 1 :) y two dimensional systol-ic arr,:iy composed of very simple cells. 'rhe decoding stage is im-plementled using a 2-D array, too. The dec:ading bottleneck is eliminated. The whole architecture is pipelincd which lead to high throughput rate. Resiaue' Number System (RNS) has been used to achieve arithmetic parallelism. Figure 1 shows a general RNS based architecture. The algebraic properties of RNS provide both high speed computation ancl parallel operations. In our implementation, parallelism is achieved in three directions; each modulo processor is implemented by two dimensional systol-ic arraq composed of very simple cells. The decoding stage is implemented using a 2-D array, too. The delzoding bottleneck will be eliminated. The whole architecture wiI.1 be pipelined which lead to high throughput rate.

Reconfigurable Systolic Arrays are a generalization of Systolic Arrays where node operations and interconnections can be redefined even at run time. This flexibility increases the range of systolic array’s application, making the choice of the best systolic architecture to a given problem a critical task. In this work we investigate the specification and verification of such architectures using...
متن کاملA systolic architecture for LMS adaptive filtering with minimal adaptation delay
Existing systolic architectures for the LMS algorithm with delayed coeficient adaptation have large adaptation delay and hence degraded convergence behaviour. This paper presents a systolic architecture with minimal adaptation delay and input/output latency, thereby improving the convergence behaviour to near that of the original LMS algorithm. T h e architecture is synthesized by using a numbe...
