| 摘 要： | 传统的控制算法由软件实现,运行速度相对较慢.为改善系统性能,提高系统处理速度,本文提出了基于AMBA总线的SOC硬件加速器的解决方案,并选取典型的四元数算法加以验证.本文介绍了实现四元数解算的硬件加速器设计,将该模块通过AMBA总线集成到LEON内核中,完成了系统级仿真,并在FPGA上进行了验证.结果表明SOC硬件加速器在控制系统中应用是可行的,且体现出很大优越性.

| Abstract: | The traditional control arithmetic is processed by software,and the speed is relatively low.In order to accelerate the operating speed and improve the performance of the system,the scheme of using the SOC hardware accelerator(HA) based on the AMBA bus protocol has been proposed and the typical quaternion arithmetic has been taken to prove it.The HA of processing quaternion arithmetic is designed,and it is integrate in the LEON core by the AMBA bus.System simulation and FPGA test results prove that the SOC H... |
