ABSTRACT:
A field compositor, with a regular and systematic structure, that merges fields of data together to compose new data words. Starting from a basic cell, the field compositor merges longer words by connecting more of the basic cells together in a systematic and orderly fashion. The cells are connected in a regular structure so that routing data through the compositor can be done in a similarly regular manner. The basic cell of a one-dimensional regular array has three control inputs to control two outputs, one being a data output; depending on the logic levels presented to the three inputs, data from the first or the second set of data are selected to be the data output of the cell. The basic cell of a two-dimension regular array has five control inputs and two outputs, one being a data output; depending on the logic levels of the five control inputs, data from the first or the second set of data are selected to be the data output of the cell. To reduce the time required to compose a word, a maintain-selection-lookahead-module provides input control signals for the initial cell of each row of the two-dimension regular array.
