The display controlling unit also comprises an output connectable to provide output image data representing an output image at least comprising the safety relevant information, an image enhancement module arranged to perform an image enhancement processing for the first set of image elements when a safety mode signal indicates a first mode, and a verification module arranged to perform a verification processing for the second set of image elements when the safety mode signal indicates a second mode. | 05-16-2013 |
20140129001 | SAFETY CRITICAL APPARATUS AND METHOD FOR CONTROLLING DISTRACTION OF AN OPERATOR OF A SAFETY CRITICAL APPARATUS - A safety critical apparatus comprises a set of safety relevant modules; one or more comfort modules having one or more user interfaces; and a distraction controlling device arranged to adapt at least one of the one or more user interfaces to a current situation of operation of the safety critical apparatus. The distraction controlling device comprises an operator imposition estimation unit arranged to receive a set of safety relevant status signals from the set of safety relevant modules and to provide a current acceptable-distraction threshold value depending on the set of safety relevant status signals; a distraction managing unit arranged to receive one or more comfort status signals from the one or more comfort modules and to provide a current distraction value depending on the one or more comfort status signals; and a decision unit arranged to receive the current acceptable-distraction threshold value and the current distraction value and to provide one or more deactivation decision signals for the one or more user interfaces of the one or more comfort modules when the current distraction value exceeds the current acceptable-distraction threshold value. | 05-08-2014 |
20140223128 | MEMORY DEVICE AND METHOD FOR ORGANIZING A HOMOGENEOUS MEMORY - A memory device comprising a memory controller and a homogeneous memory accessible by the memory controller, wherein the homogeneous memory is divided by the memory controller in a first memory partition and a second memory partition, wherein the first memory partition is allocated to a first type of information comprising user data and ECC data that are arranged interleaved with the user data, and wherein the second memory partition is allocated to a second type of information comprising further user data. | 08-07-2014 |
20140289357 | DATA PROCESSING SYSTEM AND METHOD OF CONTROLLING ACCESS TO A SHARED MEMORY UNIT - A data processing system comprising at least a memory unit, a first client connected to the memory unit, and a second client connected to the memory unit is proposed. The first client may comprise a first memory access unit and an information unit. The first memory access unit may read data from or write data to the memory unit at a first data rate. The information unit may update internal data correlating with a minimum required value of the first data rate. The second client may comprise a second memory access unit and a data rate limiting unit. The second memory access unit may read data from or write data to the memory unit at a second data rate. The data rate limiting unit may limit the second data rate in dependence on the internal data. The first memory access unit may, for example, read data packets sequentially from the memory unit, and the information unit may update the internal data at least per data packet. A method of controlling access to a shared memory unit is also proposed. | 09-25-2014 |
20140300615 | MEMORY ACCESS CONTROLLER, DATA PROCESSING SYSTEM, AND METHOD FOR MANAGING DATA FLOW BETWEEN A MEMORY UNIT AND A PROCESSING UNIT - 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. | 10-09-2014 |
20150109330 | DISPLAY CONTROLLER WITH BLENDING STAGE - A display controller comprising a blending stage and a blending controller. The blending stage is provided for blending multiple image layers into one display output image and comprises a plurality of input channels for receiving pixel data for the multiple image layers. The blending stage further comprises multiple blenders for combining the pixel data received by at least two input channels of the plurality of input channels. The blending controller is coupled to the blending stage for controlling operation of the blending stage. The blending stage further comprises a controllable switch for coupling an output of at least one blender of the multiple blenders to a display output of the blending stage for regular on-the-fly blending or to an offline blending memory for storing a result of an offline blending task. The blending controller comprises an input for receiving layer data describing locations and/or properties of the multiple image layers and a predictor for, based on the layer data, predicting an availability of the at least one blender. The blending controller is further operative to control the blending stage to perform the offline blending task in dependence of the predicted availability | 04-23-2015 |
20150137841 | BUILT-IN SELF TEST SYSTEM, SYSTEM ON A CHIP AND METHOD FOR CONTROLLING BUILT-IN SELF TESTS - 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. | 05-21-2015 |
20150161759 | DIAGNOSTIC DATA GENERATION APPARATUS, INTEGRATED CIRCUIT AND METHOD OF GENERATING DIAGNOSTIC DATA - A diagnostic data generation apparatus for a display controller comprises an underrun detector arranged to monitor, when in use, buffer depletion in order to detect an underrun condition. The underrun condition results from a data feed lag associated with a mismatch between a buffer fill rate and a predetermined output data rate. The underrun detector is arranged to generate diagnostic data in response to detection of the underrun condition, the diagnostic data identifying the underrun condition and a location in an array of pixels associated with the underrun condition | 06-11-2015 |
