同步加速器的磁场控制系统系高精度的实时控制系统.随着CSR工程的进一步改造要求,以及数字化处理技术的不断发展,对浮点乘法的运算速度以及相应占用资源也提出更高要求.本文通过VHDL语言和BOOTH算法实现的优化乘法器,采用了结合3-2压缩器和4-2压缩器的树型结构,并以CycloneⅢ芯片EP3C25F256为硬件环境,进行了功能和时序仿真,与其他设计的仿真结果比较,验证了该浮点乘法器的正确和高速特性.

The magnetic control of a synchrotron is a high precision real time system. With the development of digital processing, the HIRFL-CSR project (Cooler Storage Ring of the Heavy Ion Research Facility in Lanzhou) has higher requirements on floating multiplier's speed and used-resource. In this paper, we report the improved floating multiplier realized by the VHDL and the Booth algorithm, based on the tree-structure consisting of the 4-2 and 3-2 compressors. It takes the EP3C25F256 as the hardware environment to get the timing-emulate and function-emulate. Comparing with other designs, this floating multiplier has better in correction and speed.
