Parallel-to-serial conversion device and linear transformation device making use thereof

摘要

A parallel-to-serial conversion device capable of improved space efficiency has a corner turn memory array provided in an input section of the device to perform parallel-to-serial conversion by writing in the row direction of the input section and by reading out in the column direction of the input section, write section for selectively writing data into a first pair of memory cells of said corner turn memory array; and readout section for simultaneously reading data from a second pair of memory cells which are different from the first pair of memory cells.
