Lossless Time Based Data Acquisition and Control in a Distributed System

摘要

Systems and methods for mapping a time-based data acquisition (DAQ) to an isochronous data transfer channel of a network. A buffer associated with the isochronous data transfer channel of the network may be configured. A clock and a local buffer may be configured. A functional unit may be configured to initiate continuous performance of the time-based DAQ, transfer data to the local buffer, initiate transfer of the data between the local buffer and the buffer at a configured start time, and repeat the transferring and initiating transfer in an iterative manner, thereby transferring data between the local buffer and the buffer. The buffer may be configured to communicate data over the isochronous data transfer channel of the network, thereby mapping the time-based DAQ to the isochronous data transfer channel of the network.

1. A method for configuring the mapping of a continuous time-based data acquisition to an isochronous data transfer channel of a network, the method comprising:
configuring a local buffer for receipt of data from the continuous time-based data acquisition; configuring a first buffer for receipt of data from the local buffer, wherein the first buffer is associated with the isochronous data transfer channel, wherein the isochronous data transfer channel has an associated bandwidth, and wherein said configuring the first buffer reserves the associated bandwidth; configuring a functional unit to:
initiate performance of the continuous time-based data acquisition, wherein the continuous time-based data acquisition is performed according to a first clock, wherein the data from the continuous time-based data acquisition is stored in the local buffer; andinitiate continuous transfer of the data from the local buffer to the first buffer, wherein the transfer from the local buffer to the first buffer is performed according to the first clock.
