Programming Technologies Routing Architecture CLBs Advantage & disadvantage of FPGA ReferencePowerPoint Presentation: What is FPGA? Field-Programmable Gate Arrays (FPGAs ) are two dimensional array of logic blocks and flip-flops that can be electrically programmed to become almost any kind of digital circuit or system. Block diagram of fpgaPowerPoint Presentation: Programming Technologies It is used to control the programmable switches that give FPGAs their programmability. There are a number of programming technologies but the flash, static memory and anti-fuse are widely used in modern FPGAsPowerPoint Presentation: 1. Static Memory Programming Technology 2. Flash/EEPROM Programming Technology : 2. Flash/EEPROM Programming Technology Non Volatile Fast Cannot reprogrammed an infinite no. of times use non standard cmos process3. Anti-fuse Programming Technology: 3. Anti-fuse Programming Technology this link is permanent. The primary advantage of anti-fuse programming technology is its low area. Non-volatility also means that the device works instantly once programmed.Routing Architecture: Routing Architecture The programmable routing in an FPGA provides connections among logic blocks and I/O blocks. It consists of wires and programmable switches.1. Hierarchical Routing Architectures: 1. Hierarchical Routing ArchitecturesPowerPoint Presentation: 2. Island-Style Routing ArchitecturePowerPoint Presentation: 3. Unidirectional Single-Driver Routing ArchitecturesPowerPoint Presentation: 4.Pipelined FPGA Routing StructuresPowerPoint Presentation: CLBs Each Virtex -II CLB contains four slices Local routing provides feedback between slices in the same CLB, and it provides routing to neighboring CLBs A switch matrix provides access to general routing resourcesPowerPoint Presentation: Slice 0 LUT Carry LUT Carry D Q CE PRE CLR D Q CE PRE CLR Simplified Slice Structure Each slice has four outputs Two registered outputs, two non-registered outputs Two BUFTs associated with each CLB, accessible by all 16 CLB outputs Carry logic runs vertically, up only Two independent carry chains per CLBPowerPoint Presentation: Advantage of FPGA Reusability, and lower non-recurring engineering cost. Weak economy asking for low-cost technologies. FPGA can be re-programmed in the field to fix bugs. FPGA offers time-to-market advantage.PowerPoint Presentation: Disadvantage of FPGA Not a right device for high volume applications. Costlier than custom ICs. No on-chip analog functions Higher power consumption compared to ASIC.References: References http ://www.eecg.toronto.edu/~vaughn/challenge/fpga_arch.html http ://www.altera.com/literature/hb/cyc2/cyc2_cii51002.pdf http ://www.altera.com/literature/hb/stratix-iv/stx4_5v1_01.pdf Dean Takahashi, VentureBeat .
