摘要
在FPGA中实现DSP和计算机常用的IEEE单精度32位浮点表示方式,通过模块化设计,能够进行相关的浮点加法和乘法操作。利用内部逻辑单元、乘法器、ROM、RAM等资源,经过正确的逻辑控制和可靠的时序设计,设计了一个能对激光陀螺信号进行高速、精确滤波的专用滤波器,并且更简便实现后续DSP或计算机对滤波数据的格式处理。
The IEEE 32-bit single-precision floating point is realized in FPGA which is commonly used in DSP and computer. Through the modular design, correlative floating-point addition and multiplication operation are realized. Using internal logic unit, multiplier, ROM, RAM and other resources, through reliable timing design and the correct logic control, a filter is designed, which realizes the high speed and high accuracy filtering of the laser gyro output signal. This design make it easier to process follow-up data format of filtering result by DSP or a computer.
