First, the font height is in R7, and the first line is from R2. R2 is the second parameter passed in by this function, so there are two ways to change it: first, change mov R7 and R2 to mov R7 and 0x0e. No matter what parameter is input, the result is the 0x0e font. Another method is to change it outside the function:

I. background
In the process of program debugging, a problem occurs. After the program goes into the stack and goes out of the stack, it always runs and uses GDB for debugging. After the stack operation is found, check that the data after the stack is imported does not match when the stack is released.

Previously, it was understood that the first step is to import the stack R1,
the 00h-1fh 32 units are evenly divided into four, each containing eight 8-bit registers, are named in R0-R7, we often call these registers as General registers. The registers in these four blocks are called R0-R7, so how to distinguish and use them in the program? Intelligent intel engineers have assigned a register-program status word register (psw) to manage them. The CPU only needs to define the D3 and
These days are quite troublesome. For RTSP server, we need to port live555 to Android. The common practice is to write an android program. MK, put it under the android source code tree, mm, you can, but I have always had a bunch of errors, and I compiled it under a separate ndk, it turned out to be normal, just in idle time, let's take a look at the compilation error prompts. I didn't find the C ++ libraries. The Compiler automatically adds these libraries to the ndk, in the android source code
divided into two parts: the operation code and the operand. The operation code represents the command function, such as ADD and sub. It represents a specific circuit in the CPU, for example, add represents the addition circuit, sub represents the subtraction circuit, and the operand represents the input and output of the function, and the input and output of the corresponding circuit.
2) currently there are four functions in common, so at least two bits are required for encoding. For example, 0
(9) Call the decompress_kernel () function of the file Misc. C to decompress the kernel at the end of the cache.(After the R2 address ). The register values are changed as follows:R0 indicates the size of the extracted kernel.R4 is the address when the kernel is executedR5 is the start address of the kernel after decompression.R6 is the CPU type value (processor ID)R7 is the system type value (Architecture ID)(10) after the reloc_start code is copied
We all know that Linux applications must use system calls to access the kernel to switch from USR mode to SVC mode. Let's take a look at its implementation process. System calling is a service provided by the operating system of the operating system. User Programs reference various services provided by the kernel through various system calls. The execution of system calls puts user programs into the kernel, this is completed by SWI soft interruption. The Soft Interrupt corresponding to the Linux
table: There is a route to each destination. Such a table is called a route table. Basic concepts:OSPF regards the entire network (subnet on the Internet or other types of networks) as an autonomous system () In each as, several physically adjacent routers (routers) and networks form an area. These areas are generally non-intersecting and divide the entire. Is an example of a typical Autonomous System Division:
Rxx represents the router, N * represents the network, 1. R1, R2, R3, R4, and N
