Latest Patents
One of his latest patents is titled "Enhanced macrocell module having expandable product term sharing capability for use in high density CPLD architectures." This invention introduces an improved, high-density CPLD that includes multiple macrocell sections. Each macrocell section can handle a large number of independent input terms and generate at least five different product term signals. The design allows for local sum-of-products (SoP) signals to be generated through a first-level OR-ring operation, with the possibility of cascading SoP signals from neighboring macrocell sections for enhanced functionality.
Another significant patent is "Scalable architecture for high density CPLD's having two-level hierarchy of routing resources." This invention features a scalable CPLD device with a two-tiered hierarchical switch construct. It comprises a Global Switch Matrix (GSM) and Segment Switch Matrices (SSMs), allowing for a large number of parallel inputs and ensuring 100% intra-segment connectivity. This design facilitates the implementation of complex 64-bit wide designs while maintaining symmetry for more finely-granulated implementations.
