Byte-enabled transfer for a data bus having fixed-byte data transfer |
摘要 |
A data bus system transfers words and word portions on a data bus between master devices and slave devices. A size bus carries a size code in fixed-byte format that identifies a number of bytes being transferred in one or more words and/or word portions of a transaction. A byte-enable bus carries a byte-enable code that identifies valid bytes of a word. An interface decodes the byte-enable codes to size codes and, where an odd-byte byte-enable code is decoded, it decodes the odd-byte byte-enable code to a plurality of size codes.
