ABSTRACT:
A complex programmable logic device (CPLD) that can be scaled upwards in size without unacceptable increases in die size or signal delays. A CPLD includes a two-dimensional array including rows and columns of function blocks and input/output (I/O) blocks programmably interconnected by a de-centralized interconnect structure. The interconnect structure includes numbers of interconnect lines segmented into shorter lengths. Programmable multiplexer circuits couple the segmented interconnect lines to the function blocks and I/O blocks. Programmable switch matrices couple the segmented interconnect lines together into longer interconnect lines of the desired length.
