Let's start with some basic knowledge of arm assembly. (We take ARMV7 as an example, the latest iphone5s on the 64-bit is not discussed)
Basic Knowledge Section:
First you introduce registers:
R0-R3: For the transfer of function parameters and return values
R4-R6, R8,r10-r11: There is no special provision, is the general General register
R7: Stack frame pointer (frame pointer). Point to the address of the previous saved stack frame (stack frame) and link register (link register, LR) on the

Earlier graphics cards were only used for display, and then 2D acceleration components were added to the graphics card, which were used for the operation of the screen, draw points, draw lines, and so on. With the need of game, three-dimensional simulation and scientific computing visualization, the demand for 3D is gradually increasing, the early drawing work is done by the CPU, to achieve realism and real-time effect, can only draw some simple wireframe model, in the 80 's, Stanford University

VRRP (Virtual Router Redundancy Protocol, Virtual routing Redundancy Protocol) is a fault tolerance Protocol. By separating physical devices from logical devices, the Router line backup function is well realized! VRRP creates a group of routers in the LAN into a backup group, which is equivalent to a virtual router. hosts in the LAN set their default route next hop to the IP address of the vro. the host in the Network communicates with other networks through this virtual router.The extension dia
