Latest Patents
One of Lau's latest patents is titled "System and apparatus including lowest priority logic to select a processor to receive an interrupt message." This invention includes an apparatus, such as a bridge, designed for use in connection with a computer system. The apparatus features remote priority capture logic that holds task priority data indicative of the task priority of each processor in the computer system available for lowest priority interrupt destination arbitration (LPIDA). Additionally, the apparatus incorporates lowest priority logic to perform the LPIDA, selecting which processor in the computer system will receive an interrupt message based on the contents of the remote priority capture logic. Another embodiment of this invention includes a multi-processor system with processors and a processor bus coupled to them. This system also utilizes remote priority capture logic and lowest priority logic to manage interrupt messages effectively.
Another notable patent by Lau is the "Mechanism for delivering interrupt messages." In this invention, an I/O agent delivers the interrupt message through a chipset to a system bus connected to multiple processors. The interrupt message contains the transaction type and a destination identification. The servicing processor on the system bus matches the destination identification with its own to determine if it is the intended recipient. The I/O agent writes the data associated with the interrupt into a buffer queue inside the chipset, which automatically flushes the contents to the main memory before delivering the interrupt message. This delivery mechanism simplifies the process and reduces delays in handshaking operations between the chipset and the I/O agent.
