Nevertheless, these DSP algorithms are often built frommany constituent canonical subtasks (e.g., IIR and FIR filters, FFTs)that can be reused in other subtasks. Design is then a problem ofcomposing these core e

Introduction,8 months), lack of easy upgrades for legacy ASICs, very little hardware design reuse via libraries of DSP modules, and little capability to combine algorithmic design with lower level implementation tradeoffs. The traditional approach to design ASICs has always been through the following iterative procedure:

Background, as — design turnaround, flexibility, ease-of-use, and performance. Section 2.4 introduces a cost model originally proposed by Synopsys and Xilinx that compares the ASIC and FPGA alternatives. This cost model and assumptions made will serve us later, when we compare our proposed design methodology with other high-level approaches.

Introduction,n set of design specifications through the use of library of functional cores. ASICs are the method of choice in DSP, when very high sample rates are sought in combination with low power and area requirements. Their drawback in comparison with programmable DSPs has been their long design times (12–1

Conclusions,rates, though this situation seems ready to change. Estimates show that the capability (in terms of gates) to design efficiently would lag considerably behind the capability to manufacture ASICs. New factors that influence the design of ASICs are also to be taken into consideration. These include; d
