Abstract

The need to translate between various data formats, such as EBCDIC and ASCII, is common. Communications between computers may take place through direct coupling, communication lines, or interchange media, such as tape or diskette. For two systems operating with different data types to communicate, translation is required somewhere in the communication path between them. The drawing shows a hardware method of translation with exception checking and diagnostic capability. Outbound 8-bit data is gated through selector D to data translator F. The data is translated and wrapped back to translator E through selector G. Comparator A checks to make sure that this data matches the original data to be translated.
