查询词典 firtree

During the migrating and optimizing process of targeted platform, this paper starts with the analysis on complexity of H.264/AVC algorithms, carries on plenty of tests, uses a series of optimizing methods aiming at the special hardware resources of PWBSP-16 platform: optimizing modules including SAD Calculate, Integer Transform and Quantization in the instruction level by using FIRtree instruction set; optimizing it by improving coding process and enabling co-processor such as VLx、DMA in system level by the thinking of modules parallelism maximizing; putting forward the future optimizing mind in the level of algorithms.

在目标平台的移植优化过程中，本文从H.264/AVC编码算法的复杂度分析入手，进行了大量的测试分析，并针对PWBSP-16 DSP处理器特殊的硬件资源，采取了如下一系列的优化策略：在指令级方面，采用FIRtree指令集对SAD计算、整型变换、量化等主要耗时模块进行优化；在系统级方面，采用模块并行最大化的思想，通过改进编码流程，启用VLx、DMA等协处理器等方法进行优化；在算法级方面，提出后续的优化思路。

Means the parent directory, so this command means to execute "toolchain.sh," which is in the current directory.

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。

Yes,In fact,I'm on our city ream.

是的。事实上我是我们市队的。
