Advanced logic design techniques using field programmable gate arrays (FPGAs), programmable logic devices, programmable array logic devices, and other forms of reconfigurable logic. Architectural ...

The basic FPGA cell is based around a 4bit ALU in an architecture reminiscent of the early TTL chip, the 74S181. In the Adaptive array, SRAM cells control the logic cells that drive the ALU functions.

A bit of history The first practical programmable logic chips, known as PLAs (programmable logic arrays), became available in the mid 1970s. Things really took off though when MMI introduced a ...

The 8721 PLA, or programmable logic array, was one of the chips that had to be invented to make the Commodore 128, the last of the 8-bit computers that formed the leading edge of the early PC ...

The field programmable gate array has always been a different sort of animal in the semiconductor market. While it has evolved from just a bunch of logic gates that can emulate other hardware and ...

FPGAs, as their name suggests, consist of an array of programmable cells that perform the desired logic functions.

Then Xilinx came up with the SRAM-based field programmable gate array (FPGA) that could hold from 1,000 to more than 5,000 logic gates. Unfortunately, using all those gates while still connecting them ...

Large-scale optical programmable logic array can execute complex models like Conway’s Game of Life, marking a significant advancement in optical computing Researchers have long sought to harness ...
