A Digital Signal Prophecy The past, present and future of programmable DSP and the effects on high performance applications Continuing technology enhancements have resulted in FPGAs that provide you with a million system gates in a single device capable of running at clock rates up to 200MHz. When applied to digital signal processing this enables some new and exciting applications. Xilinx’s new Virtex FPGAs combine the flexibility of a programmable digital signal processor with the performance of a custom IC and give you instant access to the highest performance technology. In this presentation we’ll look at how the dramatic increase in flexible signal processing power is impacting high performance DSP applications. ®

DSP design skyrocketed DSP Past . . . (Last Year) Capabilities in accelerating DSP Application Billions of MACs per second DSP Modeling Tools Optimal Bit Widths XC4000 & Spartan High performance & flexibility Libraries of DSP building blocks Market acceptance Optimized DSP Cores from the Xilinx CORE Generator Number of FPGA-based DSP design skyrocketed A year ago at this conference we presented the capabilities of the XC4000 and Spartan FPGA families in accelerating DSP applications. We talked about their ability to deliver performance in the billions of multiply accumulates per second, we talked about how the Xilinx CORE Generator could deliver optimized DSP building blocks and how DSP modeling tools with bit true capability allowed the DSP designer to optimise their FPGA-based solutions. The number of FPGA-based DSP design starts has skyrocketed. An independent survey conducted by Forward Concepts showed that even prior to 1998, FPGAs were used as often as custom ICs and one third as often as fixed point DSP processors. But in this fast moving technology driven marketplace last years solutions are, in some respects, ancient history. 4000 400 1997 survey concluded that FPGAs are used for new DSP applications as often as custom ICs and 33% as often as DSPs.

DSP Present . . . More DSP capacity Faster clock speeds 27 Billion More DSP capacity From 7,448 to 27,648 Logic cells Faster clock speeds 160 MHz DSP clocks 7x Increased DSP performance 27 Billion 16-bit MACs / second Lower cost 100 Million MACs per $ Billions of MACs per Second Let’s move the clock ahead a year and look at what has happened to programmable DSP solutions. With the introduction of Virtex FPGAs late last year DSP parallel processing capacity has increased seven fold. The combination of more logic cells and faster clock rates makes it is possible to achieve 27 billion 16 bit multiply accumulates per second (FIR filter benchmark) in a single Virtex device at a cost of 100 million MACs per dollar. With new DSP applications demanding more performance this technology provides capabilities beyond those of the most aggressive DSP processor technology. 4 Billion 2 Billion Data rates are above 1 MHz in 26% of new design starts Source: Forward Concepts 1997 survey Processor XC4000 V1000 8 MACs FPGA FPGA

New DSP System Level Features Efficient multi-rate FIR filters Block RAM Block RAM Block RAM More on-chip storage Distributed RAM - FIR Filter Block RAM - FFT buffers Shift registers - D.A. & serial Multiply “AND” - 200 MHz DLL - Multi-rate clocks High speed serial arithmetic Faster and efficient multipliers Simplified clock generation The Virtex family has many features that have been optimised for DSP applications. In addition to the distributed RAM feature that originally enabled efficient multi-rate FIR filters, Virtex has block memory resources that provide more on-chip storage and enable applications such as single chip, high speed parallel FFT solutions. More efficient shift registers enable better data buffering and high speed serial arithmetic, and system level features such as delay locked loops simplify clock generation and help to increase data transfer rates off-chip.
