Latest Patents

Sonali Bagchi holds a patent for a "Testable high count counter." This innovative integrated circuit counter is capable of implementing a relatively high count while being testable using a relatively low number of clock cycles. The design utilizes a linear-feedback shift register (LFSR) with n bit positions. The feedback path of the shift register includes an exclusive OR (XOR) gate that couples selected bits back to the input of the register, allowing for the implementation of a 2ⁿ-1 counter. Additionally, combinatorial logic circuitry is included to test the counter in significantly less than 2ⁿ-1 clock cycles. This advancement enables the creation of a testable 'watchdog timer' that can detect software runaway conditions in microprocessor systems, among other applications.
