Abstract
Abstract Method of communicating in a multichannel communication system especially useful with high speed and low speed devices included in the system. One or more channels or subchannels are provided and controlled for addressing devices and transmitting commands, other channels and subchannels are assigned for the transmission of volumes of data. A poll-bid-grant routine is employed in facilitating the address and command channels, and queuing means is provided in assigning the working channels.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
133 words
In a multiprocessor computer system including a first closed communication loop, a second closed communication loop, coupling means coupling said first and second communication loops, a plurality of high speed devices connected to said first communication loop, and a plurality of lower speed devices on said second loop, the method of communicating and transferring data between said devices comprising the steps of a. generating a serial bit data stream in said first loop, b. defining a plurality of multiplexed channels in said serial bit data stream, c. dedicating at least one of said channels to said second loop, d. defining within said at least one channel a plurality of subchannels, e. transferring instruction messages between devices on one of said subchannels, and f. transferring data to and from storage devices on other subchannels.
Claim 2
Dependent Claim
133 words
In a multiprocessor computer system including a first closed communication loop, a second closed communication loop, coupling means coupling said first and second communication loops, a plurality of high speed devices connected to said first communication loop, and a plurality of lower speed devices on said second loop, the method of communicating and transferring data between said devices comprising the steps of a. generating a serial bit data stream in said first loop, b. defining a plurality of multiplexed channels in said serial bit data stream, c. dedicating at least one of said channels to said second loop, d. defining within said at least one channel a plurality of subchannels, e. transferring instruction messages between devices on one of said subchannels, and f. transferring data to and from storage devices on other subchannels.
Claim 3
Dependent Claim
36 words
The method defined by claim 1 wherein said plurality of high speed devices include at least two processors and further including the step of transferring instruction messages between said processors on a second of said subchannels.
Claim 4
Dependent Claim
52 words
The method defined in claim 2 wherein one of said processors controls the first subchannel and including the step of periodically polling said devices on said second loop and said processors on said first loop and granting said first subchannel to a device in response to a device bid for said subchannel.
Claim 5
Dependent Claim
45 words
The method defined by claim 3 wherein one of said processors controls said second subchannel and including the step of periodically polling said processors on said first loop and granting said second subchannel to a processor in response to a processor bid for said subchannel.
