Latest Patents

Yair Hadas holds a patent for a method titled "Method of prechecking the validity of a write access request." This invention provides a method and apparatus for prechecking the validity of an access request for writing result data to an external system before executing the instruction that generates the result. This process allows for uninterrupted instruction execution in the event that the write is permitted. The microprocessor's Address Unit issues a 'probe' request to the Memory Management Unit (MMU) via an internal bus while saving the instruction's virtual address in a local buffer. The MMU checks the validity of the 'probe' request without converting the virtual address to a physical address, issuing an access grant signal that is saved for subsequent use. The Execution Unit processes data in parallel to the MMU's validity check, ensuring efficient operation.
