Abstract

This article proposes the use of a novel storage means in connection with a communications system. Most communication systems employ first-in, first-out buffers of limited capacity for diagnostic purposes. The present structure involves the sequential storage of incoming information in a buffer of limited capacity wherein once the buffer fills, the oldest information is moved out or dumped out and consequently lost. Each block of variable length data input into the buffer must include an identifying (ID) byte. If this byte were a header byte, then it would eventually be dumped and lost before the remainder of its associated block of data. Consequently, this article proposes using a trailer identifier byte for each block instead of a header.

Temporary Storage Means For Communications System

This article proposes the use of a novel storage means in connection with a communications system. Most communication systems employ first-in, first-out buffers of limited capacity for diagnostic purposes. The present structure involves the sequential storage of incoming information in a buffer of limited capacity wherein once the buffer fills, the oldest information is moved out or dumped out and consequently lost. Each block of variable length data input into the buffer must include an identifying (ID) byte. If this byte were a header byte, then it would eventually be dumped and lost before the remainder of its associated block of data. Consequently, this article proposes using a trailer identifier byte for each block instead of a header. In order to make certain that, as the block of data in the buffer is being accessed for use, an identifier is available, the present approach makes use of an auxiliary one-byte buffer in which the identifier for the input block of data is stored prior to reaching the trailer ID byte. Once the trailer ID byte is reached, the identifier is removed from the auxiliary buffer and an identifier for the next block to be input is substituted.
