cpcie规范

ATCA 即先进的通讯计算机架构，是PICMG组织专门为电信系统制定的规范，PICMG 3.0

两个月前从picmg官方网站上下的，最近再去，找不到免费的了，开始收费了。希望对想学习或研究的兄弟姐妹们有所帮助。 PICMG 3.0 Revision 3.0 AdvancedTCA Base Specification February 19, 2008 先进电信运算架构（ATCA）又被称为PICMG3.X，是用于满足高吞吐量、高可靠性的新一代计算机平台标准，该标准将为电信行业制定全新的刀片式产品和机箱外形技术提供规范。目前，ATCA正由PCI工业计算机制造商协会（PICMG）进行开发，协会致力于满足CompactPC（PICMG2.16）I及其他专有解决方案都不能满足的新一代通信应用中所提出的需要。

PICMG3.0 AdvancedTCA Base Specification February 19, 2008 英文原版，带目录，可复制、编辑。 The PICMG® 3.0 specification defines open architecture modular computing components that can be quickly integrated to deploy high performance services solutions. The specification is focused on the definition of an architecture that can: Enable reduced development time and costs Support reduced total cost of ownership Apply to edge, core, transport, and data center Apply to wireless, wireline, and optical network elements Support a rich mix of processors, digital signal processors (DSPs), packet processors, storage, and input/output (I/O) Integrate with multiple network elements Provide multi-protocol support for interfaces up to 40 Gbps Offer high levels of modularity and configurability Improve volumetric efficiency Improve power distribution and management Offer an advanced software infrastructure providing operating systems (OSs), application programming interface (API), and operation, administration, management, and provisioning (OAM&P) Offer world-class element cost and operational expense Provide high levels of service availability (99.999% and greater) through the integration of features for resiliency, redundancy, serviceability and manageability Support appropriate scalability of System performance and capacity
