Abstract: A secure processing system includes a memory having a secure partition and a non-secure partition, a neural network processing unit (NPU) configured to initiate transactions with the memory, and a memory protection unit (MPU) configured to filter the transactions. Each of the transactions includes at least an address of the memory to be accessed, one of a plurality of first master identifiers (IDs) associated with the NPU, and security information indicating whether the NPU is in a secure state or a non-secure state when the transaction is initiated. The MPU is to selectively deny access to the secure partition of the memory based at least in part on the memory address, the first master ID, and the security information associated with each of the transactions.

Abstract: The embodiments of the present application relates to a camera, comprising a first housing, a stitching lens mechanism, and a driving assembly. The stitching lens mechanism is mounted in the first housing, and the stitching lens mechanism comprises at least two first assemblies, the first lens assembly comprises a first lens, a first included angle is formed between at least two first lenses. A driving assembly is connected to the first lens assembly through a rotating assembly. At least two first lenses are distributed in a first plane, the first housing is rotatably arranged in a second plane, and the second plane is perpendicular to the first plane. Each of the first lens assemblies takes pictures in different orientations for the same scene, so that the imaging field of view is larger. So that the first housing can rotate under the drive of the driving assembly, that is, the stitching lens mechanism can rotate.

Abstract: A method and apparatus for controlling access to memory is disclosed. In one implementation, a memory controller may receive a memory access request that may include a virtual memory address, a device identifier (ID) and a protected access indicator. Additionally, the memory controller can receive page table entries including a physical memory address based on the virtual memory address and a security attribute associated with the physical memory address. The memory controller may access a memory based on the physical memory address, the security attribute, the protected access indicator, and the device ID.

Abstract: Disclosed is a video camera, comprising a lens assembly, an upper shell assembly and a lower shell assembly. The upper shell assembly covers the lens assembly. The lens assembly is fixedly connected to the upper shell assembly, and both the lens assembly and the upper shell assembly are provided on the lower shell assembly so as to be rotatable in P-direction. The upper shell assembly is provided with a first protrusion, and the lower shell assembly is provided with a second protrusion, and the first protrusion and the second protrusion are press-fitted to each other so as to limit the rotation of the lens assembly in P-direction relative to the lower shell assembly. The rotation adjustment of the lens in P-direction can be realized by directly detaching the first protrusion from the second protrusion without removing the upper shell assembly from the lens assembly, which is convenient to operate.

Abstract: The present application relates to a panorama stitching camera, including: a base provided with a fixing plate; a main shaft passing vertically through the fixing plate; and a plurality of lenses disposed at one end of the main shaft, wherein, a limiting protrusion and a shaft end retaining ring that abut respectively against two opposite sides of the fixing plate are disposed at the other end of the main shaft. When the angle of view of the panorama stitching camera is being adjusted, the plurality of lenses can rotate around the axis of the main shaft simply by rotation of the main shaft. Thus, the adjustment of the angle of view of the lens along the circumferential direction of the main shaft is achieved, and the operation of adjusting the angle of view of the panorama stitching camera is greatly simplified. Thus, the problem that the angle of view of an existing panorama stitching camera cannot be adjusted readily during use is solved.

Abstract: Devices, systems, methods, and other embodiments associated with decoding image data are described. In one embodiment, an apparatus decoding a bitstream includes a parser that parses a command that includes instructions for decoding a syntax element bitstream from the bitstream. The parser functions to identify a number times to repeat the command and to identify a table associated with the syntax element bitstream based, at least in part, on a table identification (ID) in the command. A decoder decodes the syntax element bitstream as specified by the command based, at least in part, on retrieving a value in a table associated with the table ID to generate a syntax element.

Abstract: Devices, systems, methods, and other embodiments associated with a buffer controller are described. In one embodiment, an apparatus includes a buffer to buffer data. The apparatus further includes a status register and control logic. The control logic at least processes write commands. When the buffer is full and a write command to write data to the buffer is received, the control logic is configured to: accept the data without writing the data to the buffer, send an acknowledgment that the buffer was written, and set an overflow bit in the status register.
