translator presses: that is, either the transit interface activates MPLS).This case shows how to: on the ingress router (R1), use R7 's loopback port address (10.0.9.7) to define an LSP from R1 to R7. 10Mbps bandwidth is reserved for MPLS in the following configuration. Additionally, this configuration disables the CSPF algorithm to ensure that the rsvp-signaled LSP used by the host C1 and C2 is consistent

B, like no b is called). In the above illustration, a stack frame has a stack frame pointer storage area (saved frame pointer) in addition to the already mentioned parameter region (parameter area), Link region (linkage area), and local variable storage (area storage). Register store (saved registers area), the stack frame register is no longer explained, register Store: Save nonvolatile Register (R4,R5,R6,R8,R10,R11), the following assembly code examples will be introduced.

RX460 and GTX950. Nonsense not to say, or first to see the two sides of the war graphics card, because the market basically can't buy these two chips of the public version card, so we can only filter the Non-public version of the card as a representative, this will be more close to the real purchase situation. AMD RX460 The aspect is the Sapphire RX460 Ultra Platinum OC. This top AIB Sapphire RX460 pro

skim a lot more than 1500 yuan of high-end card, I believe that about 1000 yuan graphics card is some light game players and ordinary consumers the best choice, and look at the current market on the sale of the thousand-level graphics cards, in addition to Nvidia GTX950 on the non-AMD RX460 mo; Below we pass some examples to see these two chips which is superior to the inferior, hopes to give the thousand yuan buys the card User a reference. Nonsense not to say, or first to see the

. Address. Base Address addressing is used to access storage units near the base address. It is often used for table queries, Array Operations, and access to non-register functions. Q Example: LDRR2, [R3, # 0x0c]; Read the content of the storage unit pointed to by the R3 0x0c address, and put it in R2 StrR1, [r0, #-4]!First R0 = R0-4, and then store the value of R1 to the Unit pointed to by R0 LDRR1, [r0, R3, LSL #1]Read the content of the Unit on R0 R3 * 2 and store it in R1. 6. Relative addres

The problems that arise: A) R1 has a 7.7.7.0/24 route on it, but Ping 7.7.7.7 is not reached. (R7 same) Now view the R1 routing table R7#sh IP route B 1.1.1.0 [20/0] via 5.5.5.5, 00:02:54/To save space incomplete display It can be seen that R7 learned the route of the R1, from the surface to see the experiment is perfect, for the purpose, but then the proble

the address pointer of the operand. Examples of indirect addressing commands in registers are as follows:LDR R1, [R2]; reads the data of the storage unit pointed to by R2. stores the data in R1.SWP R1, R1, [R2]; exchange the value of register R1 with the content of the storage unit pointed to by r2 5. Multi-register addressingMultiple register addressing can transmit several register values at a time, allowing one instruction to transmit any subset or all registers of 16 registers. Examples of

immediate number (24 bits low ). The following code can be found in entry-common.S. In section 2.6.21, you will find that you cannot avoid this concept. What is Eabi? In the kernel, the interview with Eabi and oabi is actually relative to the method of system calling. Of course, the system we call is limited to the arm system.Eabi (Extended Abi) is a new method of calling the system. MoV R7, # numSWI 0x0 The original system call method is as follows

right is after the call. When B returns, it should return to the Left State (A is before B is called, just like calling B ). In a stack frame, apart from the previously mentioned parameter area, link area, and local storage area) besides, the stack frame pointer storage area (saved frame pointer) and the register storage area (saved registers area) have been introduced above (R7); the register storage area: save non-loss-prone registers (R4, R5, R6,

Set display, single display hybrid dual graphics technology has a long history, and experienced a number of generations, and the only has a set of obvious, unique AMD in this respect has a unique advantage. Now, the new release of the Catalyst 14.1 Beta added to the Kaveri Apu Dual graphics support, together to see how the match, the effect of how. The Catalyst Control Center can be checked to turn on dual graphics. Kaveri APU Dual Graphics combination The table looks

next points to the process to be switched. Let's talk about the code I transplanted. Since the code is a assembler, first introduce the CPU structure. The cpu I use uses 16-bit commands, 32-bit addresses and data. There are 16 General registers recorded as R0-R15. R0 as the stack pointer register sp, R1 usage is not fixed, r2-r6 as the parameter transfer register, function call if there are no more than five parameters, the parameters are placed in R2-R6 from left to right. At the same time, R2

= tag_next (tag_array ); ...... Tag_array-> hdr. tag = ATAG_NONE; Tag_array-> hdr. size = 0; Tag_array = tag_next (tag_array ); Finally, copy the linked list of kernel parameters to the default physical address 0x20000100 of the kernel. In this way, the parameter linked list is created. 4. kernel receiving Parameters The following describes how the Linux kernel receives the kernel parameters passed by BootLoader from the zImage Image Based on the ARM architecture. Shows the zImage startup pro

Most people who have studied single-chip microcomputer know the names of "Water lamp" or "horse lamp". The specific implementation effect is to display a group of changes cyclically according to a fixed rule. For example, if you use a byte length space to realize the "marquee", you can change the value of this Byte as follows: "0000 0001b"-> "0000 0010b"-> "0000 0100b"-> "0000 1000b"-> "0001 10000b"-> "0010 10000b"-> "0100 10000b" -> "1000 10000b"-> "0000 0001b" (loop) For example, to change th
