浮点计算机

An FPU ( Floating-Point Unit) is the principal component in graphics accelerators, DSPs ( Digital Signal Processor) and high performance computer systems.
浮点单元FPU（FloatingPointUnit）成为图形加速器、DSPs和高性能计算机的基本部件。
The traditional image compression based on wavelet transform coding, wavelet transform coefficients are floating-point type, and the process of quantify inevitably produces different degrees of distortion because of computer rounding errors of floating point operations, so it cannot be directly used for lossless image restructure.
传统的基于小波变换的图像压缩编码中，变换后的小波系数是浮点型的，量化过程中由于计算机的浮点舍入误差运算必然产生不同程度的失真，因此不能直接用于图像的无损重构。
Firstly, the using chaotic systems are based on floating-point operations on the real number field, both encryption and decryption will bring the problem of the key non-synchronous because of the computer word length different.
一是加解密算法中所用混沌系统是基于实数域上进行的浮点运算，加解密双方会因计算机字长不同而产生加解密密钥流不同步的问题。
For simple floating-point function conversion, it adepts coordinate rotation digital computer ( CORDIC) algorithm.
其中对单纯浮点函数转换，采纳了坐标旋转数字计算机（CORDIC）算法实现。
