基于ARM9的通用IPMC载板设计

Design of Universal IPMC Board Based on ARM 9

摘要:

针对ATCA构架体系中由IPMC没有完全按照规范要求设计而引发的兼容性差的问题,提出一种基于ARM 9的通用IPMC载板设计方案;该方案以ARM 9嵌入式微处理器为核心,设计了合理的硬件电路,符合PICMG 3.0规范和IPMI 2.0标准,可以适应各种背景的ATCA板卡管理；选取Radisys机箱作为实验平台,IPMC载板可以实现对ATCA板卡的管理并且与机箱管理进行可靠通信,有效验证了载板的可行性和通用性；通过将载板搭载在不同的FRU上进行实验,结果证明载板具有良好的兼容性。

Abstract:

For many IPMC can not be designed as the specification required, the ATCA system always be in low compatible, so an ARM 9 based universal IPMC board design is proposed. The project takes ARM 9 as a core, designs appropriate hardware circuit, accords with PICMG 3.0 Criterion and IPMI 2.0 Standard. It can adapt to kinds of background ATCA boards management. Choose Radisys shelf as experiment platform, IPMC board can achieve to manage the ATCA board and communicates with the ShMC reliable. The feasibility and generality are proved by the test effectived. Fix the board onto different FRU, the result tells that the board owned great compatibility.
