The present invention relates to a bandwidth estimation circuit for estimating and predicting the bandwidth of a computer system, the bandwidth estimation circuit comprising: a memory unit which is configured to store multiple predetermined bandwidth envelopes, wherein each one of the predetermined bandwidth envelopes is assigned to a feature of a code of an application program; a bandwidth measurement unit which is configured to online measure the bandwidth of a data transaction based on the code; a selection unit coupled either to the memory unit and the bandwidth measurement unit and configured to find the nearest bandwidth envelopes in the memory unit for the measured bandwidth; a calculation unit which is configured to calculate a ratio between the selected bandwidth envelopes, to construct a new bandwidth envelope by applying an interpolation function based on the calculated ratio and to calculate an estimated bandwidth by applying the new bandwidth envelope. The present invention also relates to a computer system, a method for estimating and predicting the bandwidth and a computer readable program product.

The present application relates an encoder. The encoder partitions an image domain into several substructures each having one of at least one size dimension, and defines at least one geometric primitive for each substructure on the basis of geometry data. The encoder also retrieves, for each substructure, a subset of image data and determines whether pixel values of the retrieved subset are the same. If the pixel values are describable by a texture mapping operation, then the encoder defines a compressed texture image and assigns texture mapping data to the geometry data. Otherwise, the encoder defines an uncompressed texture image and assigns texture mapping data to the geometry data. The compressed image includes the geometry data, the texture mapping data, and the texture image data.
