An Improved Design of the Carrier Communication Digital Multiplexer Implemented on Sports Venues

The electric carrier communication is the special communicated way of electrical power system In this paper, one kind of double CPU, the low power loss, the low cost digital multiplexer has been designed in conducted the full research to this communicated way, which is satisfied the need of the electric power correspondence transmission system , especially in sports venues. In respect of hardware designing, dual-port RAM and double CPU are adopted for coordinating work and greatly improving efficiency; dual-port RAM , which functions as a shared mailbox of double CPU, is used to store markers, pointer and coordinate the work of double CPU. This article is elaborated the digital multiplexer’s hardware and the software principle of design in detail, carries on the simulation using the monolithic integrated circuit simulator, has achieved the satisfactory effect through the debug .
