What is Reconfigurable Computing? Reconfigurable computing (RC) is the study of architectures that can adapt (after fabrication) to a specific application or application domain Involves architecture, design strategies, tool flows, CAD, languages, algorithms

What is Reconfigurable Computing? Alternatively, RC is a way of implementing circuits without fabricating a device Essentially allows circuits to be implemented as “software” “circuits” are no longer the same thing as “hardware” RC devices are programmable by downloading bits - just like software Processor         Processor 001010010 0010 Bits  loaded  into  program  memory Microprocessor  Binaries b a c x y 001010010 FPGA Binaries  (Bitfile) Processor         FPGA 0010 Bits  loaded  into  CLBs,  SMs, etc.

Why is RC important? Tremendous performance advantages In some cases, > 100x faster than microprocessor Alternatively, similar performances as large cluster But smaller, lower power, cheaper, etc. Example: Software executes sequentially RC executes all multiplications in parallel Additions become tree of adders Even with slower clock, RC is likely much faster Performance difference even greater for larger input sizes SW time increases linearly - O(n) RC time is basically O(log2(n)) - If enough area is available for (i=0; i < 16; i++)     y += c[i] * x[i]
