ASR9K
CPU
这张图涵盖了ASR9000 全系列板卡的架构以及使用的芯片， 其中最右边一列为CPU的类型； 可以看到最初一代和二代板卡使用的都是PowerPC的处理器， PowerPC采用的都是32位的指令集， 这也是为什么这两代板卡没法跑在最新的64位XR系统上的原因。最新的三代采用的都是Intel的处理器， 使用以下命令我们可以查看板卡处理器（CPU）的类型:
0/0/CPU0 使用的是四核E500型号的CPU， 0/6/CPU0 采用的是8核英特尔686。

NPU and Fabric
图示最左侧是NPU ASIC （network process unit）， 我们所说的cef表象之类的是存储在这类芯片的on-chip TCAM上。
型号分别为Trident/Typhon/tomahawk/lightspeed/Lightspeed+, 最新一代已经达到7NM的工艺。这款芯片也是CISCO自研的。
前三代中间有个回形针一样的为FIA （fabric interface asic）用来连接右侧的Switch Fabric ASIC， 转发芯片。
最新的两代中虽然没有FIA芯片， 但你可以理解位在NP上内置类似的功能， 下面两张图显示的是前三代和最新两代FIA芯片的位置。
最右侧的织装物为Switch Fabric， 在ASR9K的LC中我们也叫它XBAR， 或者crossbar, 它与Fabric矩阵卡上使用的转发芯片是一样的。
如何去确认NPU的型号:
Trident/Typhon/tomahawk
prm_server_ty进程,“ty”代表typhon板卡
prm_server_to进程，“to”代表tomahawk板卡

Lightspeed/Lightspeed+
ls_prm_svr进程， ls代表是lightspeed或者lightspeed+芯片.

进一步判断，需要查看下面的进程”npu_server_lsp” lightspeed+ 会有npu_server_lsp 这个进程. lightspeed 则没这个进程。

同理， 如果你需要查看fabric卡的chip， 也可以使用同样的命令， 但是得在admin vm下运行:
sysadmin-vm:0_RP0# show controller sfe diagshell 0 "show unit" location 0/fc0
