Title: Image compression
Inventor: SEBASTIAN MATYSIK
IPC: H04N19/91
Filed: 2017-12-21
Abstract: A method of processing image data for transmittal to a display device involves receiving a frame of image data, the frame being divided into tile groups composed of tiles of pixels, each having a number of colour component values of a first colour space. Each tile includes a number of colour component planes of the first colour space having the colour component values for the pixels forming the tile. Each tile group is processed in an execution unit, formed by arithmetic logic units (ALUs) and a local shared memory, where each ALU includes dedicated register space for use solely by the ALU, and each tile of each tile group is processed by a number of the ALUs of the execution unit. Each ALU performs a reversible colour transformation (S1) on the colour component values from the first colour space to a second colour space and discards the remaining colour component values and then performs a discrete wavelet transformation (S2) on the colour component values of one colour component plane of the second colour space to produce wavelet coefficients, which are quantized (S3) and entropy encoded (S4) into variable length codes. The variable length codes for all the tiles of the tile group are assembled together for transmittal to a display device. Each ALU stores the data at each stage of the processing in its dedicated register space but not in the local shared memory of the execution unit.

Title: Artificial Neural Networks
Inventor: CAGLAR AYTEKIN
IPC: H04L67/00
Filed: 2018-02-26
Abstract: A system comprises a controller and a plurality of communication devices 23-27, wherein the controller transmits signalling data to each device over a communications network. The signalling data causes each device to initialise a subset of local layers of a multi-layer artificial neural network architecture, with each device providing a different combination of layers. Assigning a combination of layers to each device forms a distributed neural network. The signalling data may indicate the topology of the layers, and this may define the number of nodes in each layer, the type of each layer, and the weight associated with each layer. The signalling data may also define the processing operations to be performed by the nodes in each layer. The controller may receive the computing resources and capability of each device, and may re-assign layers if an assigned device is incapable of providing a layer. The neural network architecture may be implemented in Internet of Things (IoT) devices. The method, apparatus and computer program of both the controller and one of the devices are claimed.

Title: A sensing apparatus
Inventor: MARTIN J THOMPSON
IPC: G06F11/10
Filed: 2018-08-08
Abstract: A sensor apparatus containing a sensing means with one or more sensors and a processor unit for processing sensed data. The processor has a memory and memory controller which is able to read and write data to one or more areas of the memory with ECC protection of the data, and can also write or read data to one or more areas of the memory without applying ECC protection. The controller may read of write data to a single memory chip that contains all of the memory areas. The areas which store ECC protected data may comprise at least one contiguous block of memory that is predefined and static, or they may be defined dynamically as a function of the type of data being read or written. The controller may write data to memory without using ECC if the data has a relatively short useful life, and use ECC protection when the data has a longer useful life or is otherwise safety critical. The processor may default to protecting everything until an instruction is passed to the controller to say that an area needs no protection.
