Abstract
A method and system for quantizing a vector corresponding to an input signal is described. The vector has a plurality of components corresponding to an N-dimensional space. In one aspect, the method and system include recursively dividing the space into equal spaces having one dimension less than a previous recursion until end spaces are formed. Each end space is two-dimensional. The method and system also include asynchronously comparing the components in each end space to determine a sub-space of a particular end space having a closest match to the vector. In another aspect, the method and system include providing tree(s) including a plurality of nodes and asynchronously traversing the tree(s) to determine a closest match to the vector. The nodes correspond to ANDs of comparisons between the components. Each comparison determines whether a first component is greater than a second component.
