Abstract

In the dual-core embedded processing systems,how to carry out effective communication between the host processor and the vice-processor became particularly important.The program based on embedded fingerprint identification system,introducing the design of communication between ARM and DSP,presenting the driver based on Linux and the hardware joints.The host computer ARM can ac-cess the entire on-chip RAM of the DSP 5416 by DSP’s HPI interface and fully agreed with the real-time embedded system requirements.
