Latest Patents
One of Takata's latest patents is titled "Methods and systems for maintaining cache coherency in multi-processor systems." This invention provides a data processor capable of reducing power consumption during the execution of a spin wait loop for a spinlock. The CPU executes a weighted load instruction while performing a spinlock process and outputs a spin wait request to the corresponding cache memory. When the cache memory receives this request, it temporarily halts the output of an acknowledge response to a read request from the CPU until a predetermined condition is met. This innovative approach allows for the stalling of pipeline execution, thereby reducing power consumption during the execution of a spin wait loop.
Another notable patent is related to a "Multiprocessor system." This invention introduces a technique for processing multiple interrupt causes that share a single interrupt request across different processors. The interrupt controller outputs an interrupt request when notified by multiple interrupt causes. The processor that accepts this request determines whether the relevant interrupt cause has occurred and executes the necessary processing. If the interrupt cause has not occurred, the processor notifies another processor to handle the other interrupt causes sharing the request.
