glue logic

glue logic

A simple logic circuit that is used to connect complex logic circuits together. For example, an ASIC chip may contain large functions, such as a microprocessor, memory block or communications block, which are tied together via small amounts of glue logic. At the printed circuit board (PCB) level, glue logic may be implemented with simple "jelly bean" chips ("glue chips") that contain a few gates all the way to programmable logic devices (see PLD). See IC macro, standard cell and discrete logic.
