International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, California Equipment for data collection and recording has widespread use in a variety of engineering applications. This paper deals with the use of multiprocessor-based architectures in digital data acquisition systems, emphasizing advantages in terms of flexibility and overall system throughput, and the characteristics of the embedded operating system. An overview of the basic architecture of typical data acquisition systems is first presented, followed by a description of a multiprocessing architecture for data acquisition in real-time environments where multiple sampling rates are employed to monitor analog and digital data from different sources. Software and hardware techniques are covered, including the multiplexing of analog signals, digital signal processing, use of masking techniques in the processing of serial data streams, and the use of multi-point buses for communications with peripheral devices. The characteristics of a real-time multi-tasking operating system are analysed. This is the core of the software in any data acquisition system which must meet real-time constraints. In turn, the core of the operating system is the real-time kernel. Emphasis is put into the organization of the kernel, covering issues such as kernel primitives, service calls, interrupt service routines, process scheduling, memory management, and communications and synchronization between processes. 1992-10 text Proceedings 0884-5123 0074-9079 http://hdl.handle.net/10150/608903 http://arizona.openrepository.com/arizona/handle/10150/608903 International Telemetering Conference Proceedings en_US http://www.telemetry.org/ Copyright © International Foundation for Telemetering International Foundation for Telemetering |

International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, California === Equipment for data collection and recording has widespread use in
a variety of engineering applications. This paper deals with the use of
multiprocessor-based architectures in digital data acquisition systems,
emphasizing advantages in terms of flexibility and overall system throughput, and
the characteristics of the embedded operating system.
An overview of the basic architecture of typical data acquisition systems is
first presented, followed by a description of a multiprocessing architecture for data
acquisition in real-time environments where multiple sampling rates are employed
to monitor analog and digital data from different sources. Software and hardware
techniques are covered, including the multiplexing of analog signals, digital signal
processing, use of masking techniques in the processing of serial data streams,
and the use of multi-point buses for communications with peripheral devices.
The characteristics of a real-time multi-tasking operating system are
analysed. This is the core of the software in any data acquisition system which
must meet real-time constraints. In turn, the core of the operating system is the
real-time kernel. Emphasis is put into the organization of the kernel, covering
issues such as kernel primitives, service calls, interrupt service routines, process
scheduling, memory management, and communications and synchronization
between processes. |
