Latest Patents

Shuler's latest patents include a method and apparatus for monitoring internal bus signals by using a reduced image of the internal bus. This invention describes an apparatus and method for monitoring an internal communication path, or internal bus, of an integrated circuit. The internal bus operates at a particular frequency, while an image of the internal bus is produced at a lower frequency, making it more suitable for monitoring by test equipment. The signals are received and driven to the bus using driver/receiver circuitry, which can handle input-only, output-only, or bi-directional signals. A buffer/align unit processes these signals to produce a time-delayed version, ensuring they are in phase relative to one another.

Another significant patent is for an integrated level two cache and controller with multiple ports, L1 bypass, and concurrent accessing. This memory system allows simultaneous data retrieval from both L2 cache and main memory, minimizing latency associated with memory access. The invention enables any memory access to be interrupted in the storage control unit before any memory signals are activated, streamlining the data transfer process.
