PCI Local Bus specification 2.3 The PCI Local Bus is a high performance 32-bit or 64-bit bus with multiplexed address and data lines. The bus is intended for use as an interconnect mechanism between highly integrated peripheral controller components, peripheral add-in cards, and processor/memory systems. The PCI Local Bus Specification, Rev. 2.3, includes the protocol, electrical, mechanical, and configuration specification for PCI Local Bus components and add-in cards. The electrical definition provides for 3.3V and 5V signaling environments.

This section describes the primary objectives and scope of the PCI eXtensions for Instrumentation (PXI) specification. It also defines the intended audience and lists relevant terminology and documents.

系统刚上电时，CPU从0xbfc0.0000开始执行。这个地址在Rom空间中，在完成TLB，Cache，UART等初始化后，CPU就将代码拷到0x8010.0000开始的RAM空间(这个地址是编译Pmon时分配符号_start的)，然后跳转到initmips()，开始在内存空间的执行。 执行initmips之前，CPU做的初始化只是初步的，其作用只是为CPU在内存中运行做一些必要的准备。主要的初始化工作：PCI设备的扫描、空间映射、资源分配都是initmips（）函数所完成的。
