1) word length
字长
1.
The word length of the computation unit or memory in hardware accelerator is important to the chip area and power consumption.
而对于片内SoC专属硬件加速器,其运算单元和片内存储体的字长与芯片面积、功耗等休戚相关。
2.
In this paper,the matching relationships among the word length,the computing speed and the main memory of large digital electronic computers are briefly investigated,so we can simply,conveniently,roughly estimate the probabal value of an effective digit and the word length of a computer at a certain speed.
本文将对大型数字计算机的字长、计算速度和内存之间的匹配关系式作了简化的研究,以便简便、粗略地估计有效位数的可能值和相应速度下计算机的字长。
4) Finite word length
有限字长
1.
To analyse the chaotic time sequences by computer should consider the finite word length of the computer.
针对Logistic映射,研究了计算机字长对其混沌特性的影响,由于计算机的字长效应,混沌序列经过短暂的过渡态后演化为周期序列,使用小数据量法计算了处于过渡态和周期态的有限字长混沌序列的最大Lyapunov指数。
2.
The stability of digital filters affected by finite word length effects were studied in consideration of its practicality,aiming at precise test of the flight control software.
针对飞控软件的精度测试,结合实际研究了有限字长影响下定点数字滤波器的稳定性,分析了乘积舍入与补码溢出对系统的非线性影响,给出系统舍入稳定与溢出稳定的定义,获得了系数量化、乘积舍入以及补码溢出等误差共同影响下有限精度系统舍入稳定且溢出稳定的充分条件。
3.
The simulation results from a 2 order system show that δ operator has better performance for round off noise caused by finite word length,higher accuracy and stability than z operator.
仿真结果表明 ,与z算子相比 ,在计算机有限字长实现时 ,δ算子受舍入截尾扰动的影响较小 ,精度高 ,算法稳
5) Long field
长字段
6) VLC codewords
变长码字
1.
Direct encryption of VLC codewords will usually not result in valid VLC codewords and so the encrypted video stream is not format-compliant.
而直接加密视频码流中的DCT系数和MV变长码字会产生非法变长码字从而破坏码流格式,不利于视频通信的正常应用。
补充资料：字长
电子计算机中每个字所包含的二进制数的位数。是衡量计算机性能的重要指标之一。分固定的和可变的两种。不同型号的计算机有不同的字长。字长越长，数的表示范围越大，数的精度越高，处理数据的速率越快。
