  • 39. EMBEDDED SYSTEMS FLOATING POINT FOURIERTRANSFORM CHIPIn many applications, it is advantageous to study a signal inthe frequency domain.Obvious examples are vibration analysis for aspacecraft.Designing a chip which will produce a floating point FFT froma stream of time domain data.The input data will be typically from an A toD converter - and can be upto 16 bit wide.
  • 40. Will test the design using a fast commercially available A toD converter and an FPGA chip from Xylinx. Subsequently, the design will befabricated as an ASIC.Initial simulations indicatemay be able to handle data rates as high as 50 M Samples persecond where each sample is 16 bits wide. Thus, the speedwill be essentially limited by the A to D conversion rate. Allinternal operations are in 32bit floating point format.
