Abstract: A 3D graphics system uses encryption keys to decrypt received and stored texture tiles of a texture in accordance with received and stored texture tile status data which indicates whether a texture tiles is encrypted or not and which one of the encryption keys is used. The decrypted texture tiles are rendered and at least a plurality of the rendered tiles is encrypted. The encrypted rendered tiles are stored in a frame buffer. Buffer tile status data is stored which indicates whether a rendered tile is encrypted or not before storage in the frame buffer, and which one of the encryption keys has been used. The encrypted rendered tiles stored in the frame buffer are decrypted in accordance with the buffer tile status data.

Abstract: A device securely accesses data in a memory via an addressing unit which provides a memory interface for interfacing to a memory, a core interface for interfacing to a core processor and a first and second security interface. The device includes a security processor HSM for performing at least one security operation on the data and a remapping unit MMAP. The remapping unit enables the security processor to be accessed by the core processor via the first security interface and to access the memory device via the second security interface according to a remapping structure for making accessible processed data based on memory data. The device provides a clear view on encrypted memory data without requiring system memory for storing the clear data.

Abstract: A memory controller used to verify authenticity of data stored in a first memory unit. The memory controller includes a secure memory unit which stores a pre-stored value representative of the authenticity of the data to be written in the first memory unit. A processing system calculates a value which is representative of the data in the first memory unit after a write cycle. The calculation of the calculated value is triggered by the write cycle. The calculated value is compared with the pre-stored value in order to verify whether the data stored in the first memory unit after the write cycle has been altered in accordance with the authenticity. By comparing the calculated value with the pre-stored value authenticity of the data stored in the first memory unit after the write cycle is verified, thus preventing the memory controller from operating in case the data written to the first memory unit is not authentic.

Abstract: A vacuum cleaner is provided, including a dirt collection container, a suction unit for acting on the dirt collection container with negative pressure via a suction chamber, at least one filter element arranged between the dirt collection container and the suction chamber in the flow direction of the air sucked in by the suction unit, a filter cover covering the filter element on the clean space side, at least one rechargeable battery for providing electrical energy for the suction unit, and at least one battery receptacle. The vacuum cleaner can further include a battery lid, which includes the at least one battery receptacle, and which is arranged above the filter cover, the battery lid being transferable from a closed position in which it covers the filter cover to an open position in which a user has access on the clean space side to the filter cover, and vice versa.

Abstract: A built-in self test system comprises an integrated circuit device comprising a plurality of functional units coupled to built-in self test circuitry; a low power control unit operable to switch the integrated circuit device into a low power mode and to generate a BIST wake-up signal during or before entering the low power mode; and a built-in self test control unit coupled to the built-in self test circuitry and the low power control unit and arranged to initiate a built-in self test when receiving the BIST wake-up signal.

Abstract: A memory access controller for managing data flow between a memory unit and a processing unit is described. The memory access controller comprises an addressing unit and an unpacking unit. The addressing unit may receive an address from said processing unit and select a data location within said memory unit in dependence on that address. The unpacking unit may read a first word from the selected data location, unpack the first word into a second word by applying a data conversion scheme which depends on the received address, and provide the second word to the processing unit. The data conversion scheme may comprise, for at least one possible address, a pixel format conversion. A data processing system and a method are also proposed.
