Latest Patents
Sasahara's latest patents include a "Control device for speculative instruction execution with a branch instruction insertion, and method for same." This invention provides a device and method for implementing prediction verification control and recovery control in speculative instruction execution when a prediction error occurs. The device features a branch instruction insertion unit that dynamically adds a branch instruction following a target instruction for prediction. Additionally, an instruction issuing unit speculatively issues subsequent instructions to an execution unit without waiting for the execution result of the target instruction. A branch prediction control unit is also included, which predicts the branch destination of a branch instruction and performs verification of both branch prediction and value prediction.
Another notable patent is the "System verifying apparatus and method which compares simulation result based on a random test program and a function simulation." This apparatus verifies a system that includes a microprocessor, utilizing first and second simulators to validate the target architecture. The checkers compare the results of the verification runs from both simulators, ensuring the accuracy of the system's specifications.
