Latest Patents

1. **Methods and Apparatus for Creating a Pending Write-Back Controller**: This patent describes a write-back cache control system integrated into a multiprocessor cache memory structure. The system utilizes a high-speed synchronous packet switching bus, referred to as a memory bus, to facilitate communication between processor subsystems. Notably, when a required memory location is not available in the cache, the cache control system sends out a memory request. Importantly, it manages the replacement of cache lines without hindering processing speed by utilizing a pending write-back cache controller that buffers old cache line data.

2. **Apparatus and Method for a Synchronous, High-Speed, Packet-Switched Bus**: This patent outlines a high-speed synchronous packet-switched inter-chip bus for transferring data among multiple system buses and a cache controller. It emphasizes independent processor-side access to the cache while employing bus watchers for bus-snooping functions. The innovation incorporates an arbiter to manage data flow effectively and to minimize arbitration latency when the bus is idle, ensuring that the system operates efficiently.
