Latest Patents
One of his latest patents is a data processor that provides a fast break in program execution. This invention features a circuit that allows an SWI instruction held in a memory circuit to be switchedly input in response to an externally supplied signal. This capability enables the substitution of a program word using an internal circuit, facilitating a high-speed and reliable break in program execution. Additionally, an interrupt function separate from normal interrupts is established by setting a specified operation mode. This is particularly useful when the data processor is used as an emulator, allowing for easy breaks in user programs that include ordinary interrupt processes. Furthermore, the invention includes a function that delivers a signal indicative of the break status, simplifying external circuit requirements.
