| Abstract: | After introducing the features of embedded vision system based on ARM-DSP framework,the factors restricting the performance of embedded vision system are analyzed.Several effective optimization methods are discussed concerning not only the operating system but also the application program.The boot time is reduced by 12 seconds after tailoring the Linux kernel and root file system,and the performance of application program increased 2.5 times by optimizing codes as well as utilizing the unique NEON technique of Cotex-A processor. |
