Image processor system having multifunction look-up table units

摘要

In an image processor system, a processor includes a first two-dimensional look-up table for receiving first and second digital data as an address, a second two-dimensional look-up table for receiving an output digital data of the first two-dimensional look-up table and a third digital signal as an address, and a latch circuit for temporarily storing the output digital data of the second look-up table. The processor is flexible and the functions thereof can be varied by changing the contents of the look-up tables.
