[Abstract]:With the development of digital communication technology, embedded system and microprocessor technology, intellectualization, digitalization and miniaturization have become one of the developing trends of instruments. The open multimedia application platform (OMAP) combines the high performance, low power DSP core with the strong control performance ARM microprocessor, with its unique dual core structure, high performance and low power consumption. Widely used in automatic control and instrumentation, as well as military and sophisticated technology and other fields. In this paper, the embedded system is applied to the design of handheld phase noise measurement platform with TI's OMAP-L138 processor. The main work of this paper is to realize the design and debugging of operating system porting and data input and output channel. According to the transplant characteristics of the embedded Linux operating system and the characteristics of OMAP-L138, the porting of the embedded Linux system is realized, and the data exchange between the ARM core and the DSP core of the OMAP-L138 is realized through DSP/BIOS Link, thus the design and debugging of the data input and output channels are realized. Finally, the whole system is tested, and the test results reach the expected purpose, and provide a reference for the subsequent development of the system.
