glue logic


Also found in: Dictionary, Thesaurus, Medical, Wikipedia.

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.

Of course, deep sub-micron semiconductor processes have allowed microcontroller manufacturers to do far more than simply subsume the ye olde glue logic. Virtually all microcontroller manufacturers offer devices with a variety of on-chip analog circuits and blocks to support communication protocols such as LIN, CAN, or USB.
The custom chips include glue logic, so the physical size of the circuitry really does shrink dramatically.
There's no need for glue logic, as the chip is designed from the ground up to interface directly with the SLP_S3#, and SLP_S5# ACPI signals from Intel's i865/i875 chipsets.
44 per cent of software engineers and 40 per cent of hardware designers predicted a significant shift in the use of FPGAs away from glue logic, prototyping and ASIC replacement to become a platform for implementing flexible designs.
