本文提出了一种可编程的三角函数、对数函数、平方根、倒数等数值函数发生器的结构和综合方法。该结构采用LUT(查找表)级联作为段索引编码器,可编程地实现各种数值函数,适合于自动综合。我们已经开发了一个综合系统,将MATLAB类规格到HDL代码。我们提出并比较了三种架构实现为FPGA(现场可编程门阵列)。实验结果表明,我们的架构和合成系统的效率。
This paper presents an architecture and a synthesis method for programmable numerical function generators of trigonometric functions, logarithm functions, square root, reciprocal, etc. Our architecture uses an LUT (look-up table) cascade as the segment index encoder, compactly realizes various numerical functions, and is suitable for automatic synthesis. We have developed a synthesis system that converts MATLAB-like specification into HDL code. We propose and compare three architectures implemented as a FPGA (field-programmable gate array). Experimental results show the efficiency of our architecture and synthesis system.
