Abstract: There is disclosed a method of storing an encoded block of data in memory comprising encoding a block of data elements and determining a memory location (26) at which the encoded block of data is to be stored. The memory location (26) at which the encoded block of data is stored is then indicated in a header (406) for the encoded block of data by including in the header a memory address value (407) together with a modifier value (500) representing a modifier that is to be applied to the memory address value (407) when determining the memory location (26). When the encoded block of data is to be retrieved, the header (406) is read and processed to determine the memory location (26).

Abstract: A method of operating a graphics processor when rendering a frame representing a view of a scene using a ray tracing process in which part of the processing for a ray tracing operation is offloaded to a texture mapper unit of the graphics processor. Thus, when the graphics processor's execution unit is executing a program to perform a ray tracing operation the execution unit is able to message the texture mapper unit to perform one or more processing operations for the ray tracing operation. This operation can be triggered by including an appropriate instruction to message the texture mapper unit within the ray tracing program.

Abstract: A graphics processing system comprising storage for storing texture data representative of a plurality of texels in a texture space and a graphics processor coupled to the storage. The graphics processor comprises a texture mapping unit operable to receive request data to request the calculation of a value at a position in the texture space using an interpolation process, the request data comprising weight data representative of weights for input to the interpolation process, and process the weight data with the texture data to perform the interpolation process, thereby calculating the value at the position in the texture space.
