Latest Patents

Hirayanagi holds a patent for a data processor employing register banks with overflow protection to enhance interrupt processing and task switching. This invention addresses the issue of undesirable operation stops in data processors due to overflow in multiple register banks. The patent includes a status register that features an overflow flag to indicate any overflow conditions. When an interrupt exception occurs while data is saved in all register banks, the central processing unit (CPU) saves the data to a stack area and reflects the overflow state in the overflow flag. If the overflow flag indicates an overflow state, the CPU can restore data from the stack area back to the register set, ensuring smooth operation.
