Application Of Embedded System In The Interface Of DSP And Network

With the rapid development of internet technology, information is very important to people. traditional connection of network treat PC as the center, but in some small system of special control and digital signal processing , in order to save the cost of system and predigest the designment, people often need to adopt MCU and DSP without PC including Embedded System to achieve the interface to the network. Because of the rapid development of Embedded System, it make the achievement like that simple Embedded System of network.To make the Embedded System link to Internet , the key is how to implement the interface, and how to provide relevant protocol of network. That is to make better of two respect: (1) In hardware, we should add a network interface to the main system control device;(2)In software, we must provide relevant protocol as well as embedding the RTOS to DSP.The aim of this design is to make Embedded System link to Internet through Ethernet. Aimming at the character of limited source of Embedded System and standing out main intent of this designment, I bring forward a way in which I use TMS320VC5410 combinning Embedded System and including simple UDP, IP protocol to accomplish data transmission in Internet. Because this project has the character of low cost comparing to other Embedded System .But it has its deficiency which the software program is so complicate. The detail is the dealed data is transferred to DSP through PC, after dealing ,combining μC/OS-Ⅱ and NIC RTL8019AS We accomplished data transmission in Internet.
