摘要
在深入分析传真译码原理的基础上,提出一种新的构造一维改进的Huffman码码表的方法,并根据FPGA的特点,构造出了黑白译码表。同时,基于ALTERA公司的Cyclone系列器件EP1C20F400C7开发板,实现了该传真译码电路。文中的译码电路构造新颖,结构简单。实际测试表明,该电路稳定性、译码速度、集成度都有显著提高。
This paper analyzes in depth the fax decoding theory,proposes a new method for constructing MHC decoding,and constructs the black-and-white decoding table according to FPGA.At the same time,based on the ALTERA Cyclone series devices of EP1C20F400C7 development board,the fax decoding circuitry is realized.The circuit structure described in this paper is new and simple.The experimental tests shows that the stability decoding speed and integration of the circuit are improved significantly.
