中文摘要: |
采用FPGA进行数字信号处理的系统,总是要频繁的进行IEEE 754浮点数到十进制码的转换.设计针对FPGA的特点提出了一种以简单的移位和加减操作为核心的转换算法,并用VHDL语言编写了状态机结构的IP核.在EP1C6Q240C8芯片上实现了732个逻辑单元的使用以及69.21 MHz最大运行速度. |

Using FPGA digital signal processing systems,it always busy with IEEE 754 floating-point to BCD code conversion.Based on the FPGA design,the paper presents a simple shift,addition,subtraction operations as the core of the transformation algorithm,for a state machine strueture with VHDL language,and achieved the use of 732 logic cells and the maximum operating speed of 69.21 MHz in EPEC6Q240C8. |
