ABSTRACT:
A programmable routing scheme provides improved connectivity both between Universal Digital Blocks (UDBs) and between the UDBs and other micro-controller elements, peripherals and external Inputs and Outputs (I/Os) in the same Integrated Circuit (IC). The routing scheme increases the number of functions, flexibility, and the overall routing efficiency for programmable architectures. The UDBs can be grouped in pairs and share associated horizontal routing channels. Bidirectional horizontal and vertical segmentation elements extend routing both horizontally and vertically between different UDB pairs and to the other peripherals and I/O.
