Abstract :
Configurable logic blocks and programmable interconnections realize configurable computing. This paper proposes a configurable CMOS H-tree logic module. The module consists of a front-end, local programmable mesh and a CMOS H-tree circuit. The small, local mesh is used for 4-variable inverted input signals. The 18-transistor (9P9N) CMOS H-tree logic module could build two-input universal functions, and several frequently used three-input and four-input functions. Furthermore, the small configurable module via a feedback loop could construct a D-latch without any additional buffer. The proposed fine-grained logic module provides excellent design flexibility and functionality for configurable computing.
