Abstract
A method is provided for updating an array of data point cells in a surface or table representation of memory. The three-dimensional surface array is modeled as a square bordered by four cells with one cell at each corner. Between each array corner cell, the array spacing is typically divided into three zones. As such, nine sub-regions of the array square are defined. Depending upon which of the nine sub-regions the calculated error point falls into when accessing the array, different cells are updated. In the case of a two-dimensional table array, typically three sub-regions are defined between adjacent cells. Depending upon which sub-region the calculated error point falls into, one or both of the table array cells is updated. As a further feature of the present invention, the amount of adaptive gain applied to each cell to be updated is adjusted depending upon which sub-region the calculated error point falls within.
