Latest Patents

Among his latest patents, Hayashi developed an "Emulation system supporting representation of four-state signals." This emulation processor is engineered to support the emulation of unknown binary logic based on the non-arbitrariness of the unknown binary logic. It facilitates the generation and propagation of outputs by strategically interacting known input binary signals with unknown input binary signals that have non-arbitrary states. Furthermore, the processor addresses both combinational and sequential operations regarding the unknown binary logic.

Another notable patent by Hayashi is the "Architecture and methodology for tuning clock phases to minimize latency in a serial interface." This innovation outlines systems and methods for tuning phases of interface clocks in ASICs to create low latency channels and prevent read errors. The implementation of training processors during the bring-up time optimizes the clock phases, ensuring that data is written to interface buffers before being read out. This tuning aims to mitigate latency issues by adjusting the time lag between writes and reads, accounting for factors such as memory setup and hold conditions, clock skews, and jitters.
