Latest Patents

One of his latest patents is titled "Providing interrupt service routine (ISR) prefetching in multicore processor-based systems." This invention discloses a multicore processor-based system that includes an ISR prefetch control circuit. This circuit is communicatively coupled to an interrupt controller and multiple instruction fetch units (IFUs) of various processor elements (PEs). Upon receiving an interrupt directed to a target PE, the interrupt controller provides an interrupt request (IRQ) identifier to the ISR prefetch control circuit. Based on this identifier, the circuit fetches an ISR pointer corresponding to the IRQ identifier and selects a prefetch PE to retrieve the ISR on behalf of the target PE.

Another notable patent is "Providing private cache allocation for power-collapsed processor cores in processor-based systems." This invention describes a system with multiple processor cores, each within its own power domain. Each core is equipped with a private cache that can be power-controlled independently. When a processor core enters a power-collapsed state, the snoop controller maintains power to the private cache, allowing it to remain online. This enables data-caching operations even while the corresponding processor core is inactive.
