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.
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.
Sensors & MEMSOur Current Focus Areas:• Ion Sensitive Field Effect Transistors (expertise with the electrolyte-insulator-semiconductor systems)• Cantilever Structures for Bio-MEMS• Microfluidic structures for single cell electroporation and capillary electrophoresis
Continuing Education Programmes We can offer in-house training programmes in practically all areas of Electrical Engineering including Communication Networks, DSP, Antennas and microwaves, Speech Processing, VLSI Design, Nanotechnology, CAD Tools, MEMS, Embedded Systems, Emerging Technologies, etc.
Concluding RemarksThere is already good collaboration between EEDepartment & ISRO.The time is now ripe for more long range projects widerin scope and stronger in impact.
