  • Patent number: 12293184
    Abstract: An illegal address mask method for cores of a DSP includes: S1, initializing a core of a DSP; S2, configuring a start address register and an end address register, and taking an address range defined by the start address register and the end address register as a masked address range; configuring a first comparator and a second comparator to send out illegal address decision signals for instructions within the masked address range; S3, acquiring a PC pointer, and determining whether the PC pointer is located in the masked address range; if so, sending out an illegal address decision signal to stop an operation; if not, performing pre-decoding to obtain a memory access instruction; and S4, determining whether an address of the memory access instruction is located in the masked address range; if so, sending out an illegal address decision signal to stop an operation; otherwise, completing a memory access operation.

  • Patent number: 11526227
    Abstract: A foldable terminal apparatus, a terminal control method, a terminal apparatus, and a non-transitory computer-readable storage medium are provided. The foldable terminal apparatus comprises a terminal body and a bendable touch screen. The bendable touch screen in a bending direction has a fixed end connected to the terminal body and a free end, and the bendable touch screen is switched between a first state and a second state. In the first state, the bendable touch screen surrounds the terminal body on an outer side of the terminal body, and in the second state, the fixed end of the bendable touch screen is located on the terminal body and the free end is located outside the terminal body, such that the bendable touch screen is expanded.
