To improve efficiency of MPEG-4 encoder, the multimedia accelerator of MXL processor was utilized to implement discrete cosine transform, and some critical modules such as motion estimation, quantization and half pixel interpolation were optimized by assemble language. 为提高视频编码效率,利用处理器内嵌的多媒体加速器硬件实现DCT算法,并对运动估计、量化、半像素插值等关键部分进行汇编优化。
In this paper, we make some discussions in the central problem of the cancellation property of quasi discrete modules and obtain the following main results: ( 1) M has the lifting property if and only if any co closed submodule is a summand of M; 对拟离散的消去性作了讨论,得到如下主要结果:(1)模M有提升性当且仅当M的每一个余闭子模是M的直和项;
Study on Quasi Discrete Modules 关于拟离散模的研究
The traditional engineering testing instruments are composed of discrete functional modules connected with wires, thus, having the disadvantages of big circuit board, high power consumption, complex connection and low anti-noise ability. 传统的工程检测仪器由分立的各功能模块部分通过有线的方式组成,设备体积大、功耗等级高、连接复杂、抗干扰能力差。
