FPGA Logic Blocks can be configured to offer functions: As simple as a transistor As Complex as a CPU Slide 13 Simplified FPGA Architecture Slide 14 Block Interconnections (Switch Box) Slide 15 FPGA Logic Blocks FPGAs has four different logic block structures: 1.Crosspoint FPGA 2.Plessey FPGA 3.Actel Logic Block 4.Xilinx Logic block Slide 16 Crosspoint FPGA Crosspoint FPGA: consist of two types of logic blocks. (MMI) in 1978 Priviously FPLA by Signetics (1975) Slide 12 Field programmable Gate Arrays dimensional array of logic blocks and flip-flops with a electrically programmable interconnections FPGA provides its user a way to configure: The intersection between the logic blocks The function of each logic block. ASICs TemporalSpatial Single Processor ASIC Slow Flexible Fast Inflexible Reconfigurable Computing ? Slide 11 Programmable array logic: PAL A programmable Logic Device Used to implement combinational logic circuits First introduced by Monolithic Memories Inc. ASICs Actual computation Processor ASIC Slide 10 Processors Vs. ASICs Processors: Take longer to compute Slow Flexible Need instructions to determine what to do on each cycle ASICS: Take shorter time to compute Fast Not Flexible No instruction Same calculation every cycle Slide 9 Processors Vs.

Routing / Interconnects: Flwxibility of a Reconfigurable Device come from its routing interconnects Island Style Layout: Blocks in Vertical and Horizental routing (in FPGAs) Slide 6 What is Reconfigurable Computing? Island Style layout Slide 7 Application Specific Integrated Circuits : ASICs Used to design a system on a chip To do a VERY specific job, no reconfiguration Interconnect of standard cells Highly automated design flow ASICs design flow: 1.RTL description 2.Functional simulation 3.Synthesis 4.Design verification 5.Layout Slide 8 Processors Vs. Time Partial Reconfiguration: A part is being reconfgured while the other is performing What is Reconfigurable Computing? 3. Rate of Configuration: Reconfiguration can happen at deployment time Between execution or During execution (at Run-Time) Bit streams is used t reprogram the device at Deployment time Fine grained systems require more config. of routing Bit level manipulation High granularity (Coarse-grained) : like rDPAs Consists of big elements Optimized for standard data path applications Drawback: loosing some of its utilisation for smaller computations Word-with data paths A larger block instead of smaller connected units What is Reconfigurable Computing? Slide 5 Reconfigurable Logic Characteristics: 2. Granularity: size of the smallest functional unit (CLB) Low granularity (Fine-Grained) : like FPGAs Greater Flexibility Increased power, delay, area due to greated Qtty.
