Abstract

The invention provides a novel programmable gate array-programmable computing array chip. The programmable logic device is a monolitric chip and comprises a plurality of programmable computing units, a plurality of programmable logic chips and a plurality of programmable connections. Each programmable computing unit comprises a plurality of printing storage arrays, and each printing storage array stores a lookup table (LUT) of a basic function library. The programmable computing unit and the programmable logic unit are respectively formed on different surfaces (front surface and back surface) of the same semiconductor substrate and are electrically coupled by penetrating through the substrate connection.

Description

technical field [0001] The present invention relates to the field of integrated circuits, and more specifically, to programmable gate arrays. Background technique [0002] Programmable gate array is a semi-custom integrated circuit, which realizes customization of logic circuits through back-end process or on-site programming. US Patent 4,870,302 discloses a programmable gate array. It contains multiple programmable logic elements (configurable logic element, or configurable logic block) and programmable connections (configurable interconnect, or programmable interconnect). Among them, the programmable logic unit can selectively realize shift, logic not, AND (logic and), OR (logic and), NOR (and not), NAND (and not), XOR (exclusive or) under the control of the setting signal. ), + (arithmetic addition), - (arithmetic subtraction) and other functions; the programmable connection can selectively realize functions such as connection and disconnection between two interconnecti...
