The first sentence: MOV R7, #200 is executed only once in the entire subroutine, and is a single-cycle instruction, so it takes time 1μs The second sentence: MOV R6, #125 from ② see ④ as long as r7-1 not 0, will re

text section of kernel.__bss_start is the end of __data_loc and the beginning of the BSS section.As you can see, kernel must prepare the text segment with the initialized data segment, which is not required for uninitialized data segments and stack segments! Just set the stack pointer and the heap start address just fine! So there's no definition of stack and heap after 22 lines!. Type __switch_data,%object__switch_data:. Long __mmap_switchedA.

Analysis of OSPF external routes E1 and E2 1. when ospf publishes an external route to a single asbr, 1.1 the equivalent path in the OSPF domain of a single ASBR re-publishes the rip route on the ospf of r2. When the release type is e2 or e1, there will be two routes on r5, respectively through r3 and r4 to 10.1.1.0 (because they are equal-cost routes, this part is relatively simple, not to mention) regarding the differences between ospf external rout

Introduction: like the standard OSPF protocol, the is-is protocol is a link-state dynamic routing protocol, but it is much optimized than OSPF, reducing the routing type and LSA flooding, it is also widely used in the current network.
