ASICs, Structured ASICs, And FPGAs

摘要

How close in performance and integration are FPGAs and ASICs? Advances in FPGA architectures and the use of 90-nm process rules have allowed the latest generation of FPGAs to achieve levels of integration and performance comparable to many ASICs. The latest SRAM-based FPGAs can deliver multihundred-megahertz operating speeds. The basic logic fabric can contain millions of configurable logic gates, several million bits of RAM, dedicated multiplier-accumulator blocks, phase-locked loops (PLLs), highspeed buffers, and multigigabit seri-alizer-deserializer ports.
