BIT/BYTE CONVERSION CIRCUIT

摘要

PURPOSE:To attain rapid conversion processing by a simple constitution in respect to a bit/byte conversion circuit for executing mutual conversion between respective bits having individual meaning and a byte including these bits. CONSTITUTION:The bit/byte conversion circuit is provided with a memory 2 for writing and reading a bit string A to H having individual meaning or a byte ('0000000A') obtained by adding dummy bits to each meaning bit by a processor 1, a parallel/serial(P/S) converter 3 for reading out a bit string from the memory 2 as parallel data, converting the parallel data into serial data and successively writing the contents of the serial data to the least significant bit(LSB) positions of respective bytes of the memory 2 and an S/P converter 4 for converting serial data obtained by successively reading out the least significant bits(LSBs) of respective bytes written in the memory 2 into parallel data and writing the parallel data in the memory 2 as bit strings and constituted so as to execute mutual conversion between bits and 8 byte.
