Description:
<jats:p>This paper shows the software architecture implemented for the accomplishment of an analyzer sound level meter in one-third octave based on a Digital Signal Processor TMS320C6701 of Texas Instruments. In order to minimize the cost of the equipment, it has been done without the elements of interface with the user (keyboard and displays). For the operation and control of the equipment a laptop, or a PDA may be used. A communication RS232C is used in the local way; and in a remote way, a connection through built-in MODEM GSM. The sever application is executed in the signal processor. It has been implemented in C language and it runs on an real time operating system (DSP-Bios provided by Texas Instruments). DSP-Bios provides the management of events, queues, and timings. The application has the necessary algorithms to make the measures and sends the results to the visualizer, or to a center of remote operation by means of the GSM. The client application that is executed in the visualization element (Laptop or PDA) is developed in Visual Basic. This application can run on any Windows operating system depending on the terminal used: Windows 9x or Windows 2000 for portable ones and on Windows CE for mobile ones.</jats:p>
