Abstract

Considering the high requirement of the ability to process data, BF561 is chosen as hardware platform, which is the new microprocessor especially designed for multimedia application, so are the embedded operation system uClinux whose kernel can be configured freely and the PJSIP stack to develop the endpoint. The video telephone endpoint is achieved which integrates software and hardware, transmit data through networks, has lower power consumption. By means of online test, this endpoint works smoothly.
