Abstract: Several methods are described to jointly use the ABT (Asymmetric Binary Tree) partitioning mode and Matrix-based Intra Prediction (MEP). In a first embodiment, we propose to forbid the use of the MIP intra prediction mode, for block sizes that are resulted from ABT partitioning. In a second embodiment, we propose to allow the MIP intra prediction for block sizes not equal to a power of two in width or height, by extending the block before MIP and crop the predicted block to the original size after MIP. In a third embodiment, we propose to adapt the down-sampling of the boundary reference samples and the up-sampling of the reduced predicted blocks, to the block sizes introduced by ABT partitioning.

Abstract: The invention is notably directed to a method of programming memory elements of an in-memory computing (IMC) device. The IMC applies a SET signal to the K memory elements of said each cell to set each of the K memory elements to a SET state and reading K conductance values of the K memory elements in the SET state. The IMC adjusts, based on the K conductance values read and the target conductance value, a conductance value of at least one of the K memory elements to match a summed conductance of the K memory elements of said each cell with the target conductance value. The IMC maximizes a number of the K memory elements that are either in their SET state or in a RESET state of zero conductance nominal value, such that at most one of the K memory elements is neither in a SET state nor in a RESET state.
