A content induced transaction overlap communication (CITO) system for transmitting data over a single communication channel permits priority queuing for Senders having critical values. In one configuration, those Senders sensing the critical values transmit a word indicating the critical condition, and polling is limited to a group of sensors which include the sensor subject to the critical value.

Priority queuing technique for content induced transaction overlap

An on-the-fly data compression system for compressing the data transmitted between a data source and an ultimate utilization device. The system normally has two data compression modules implementing a conventional multi-buffering scheme and a decoder for reconstructing the compressed data to its original format. The data compression modules compresses the data using a word representation by associative processing buffer and a content induced transaction overlap transmission protocol which results in an interleaved transmission of data bits and bit position bits, the latter being indicative of the number of data bits that will be transmitted during the subsequent data transmission. The decoder reconstructs the compressed data to its original format in response to the transmitted data and bit position bits and stores them in a pair of buffers in the sequential order in which they were generated.

On-the-fly data compression system

A content induced transaction overlap communication system for transmitting data over a single communication channel between a plurality of senders and at least one receiver. The senders simultaneously transmit the highest order bits of their data word, one bit at a time in serial fashion and monitor the state of the communication channel. Transmission of data bits is terminated by all senders which detect a difference between the state of their transmitted data bit and the state of the communication channel. Bit competition performed at the end of each transmitted data word determines among those senders still having data bits remaining to be transmitted which sender has lexicographically the next smallest word and activates that sender to transmit its remaining data bits. This procedure continues until all of the senders have completed the sending of their data word.
