Latest Patents

One of his latest patents is titled "Global signal distribution with reduced routing tracks in an FPGA." This invention features an array of programmable logic cells (PLCs) surrounded by a ring of programmable input/output cells (PICs). The design allows for programmably connecting the pads of adjacent PICs to a single global-signal spine, which is directly connected to only half of the perpendicular branches. This innovative approach reduces capacitive loading on the spines, thereby increasing the speed of global signal transmission. Additionally, sharing spines and branches between adjacent PICs optimizes layout space and maintains programming flexibility.

Another significant patent is for "Bi-directional buffers and supplemental logic and interconnect cells." This invention introduces bi-directional (BI-DI) buffers that can operate in multiple modes, allowing for the implementation of various logic circuits. The BI-DI buffers support at least five operational modes, enabling them to generate different outputs based on input values. This versatility enhances the efficiency of FPGAs in implementing complex logic circuits, such as decoders and state machines.
