Latest Patents
Roger D Rothhaar holds a patent titled "Synchronous event posting by a high throughput bus." This invention introduces a bus protocol technique that removes the transaction used for posting indications of events to the host processor from the bus. The invention leverages the fact that addresses on a high-speed bus typically contain fewer bits than the entire bus width. For instance, in a 32-bit bus, the full 32-bit address space is not always necessary. The remaining bits on the bus are utilized for an encoded event tag. A bus transaction involves a first bus transfer that provides an address for writing or reading data, along with the event tag. The event tag is detected and decoded by the destination, allowing the event to be posted to the processor that monitors and responds to events in a synchronous manner with the completion of the transaction. Consequently, after the transaction on the bus, the message subject of the transaction is stored in memory, and notification of the event occurs automatically and synchronously with the completion of the transfer.
