嵌入式填空（Embedded cloze） The 1. ARM processor has multiple modes of operation where the user program is running. 2., Qt/Embedded uses the mechanism (process call) and (interrupt return) mechanism to implement the callback of the function. 3. Rl=2000H, (2000H) =Ox28, (2008H) =Ox87, then execute instructions LDR, R0, [R1, #8], and the value after R0 is (0x87). 4. assume that R1=0x31 and R2=0x2 execute the instructions ADD, R0, R1, R2, LSL, #2, and the value of R0 is (0x39). 5. ADS (ARM, Developer, Suite) debugger, the file transferred into the best (ADS1.2) version of the generated.Axf file, the version of the document contains some of the information transferred to try. The 6. ARM assembly language consists of pseudo operations, pseudo directives, macros, and instructions. The (pseudo operation) is a kind of special instruction mnemonic, at compilation time will be converted to the corresponding instruction, can see the instruction code in assembler disassembler. 7. in ATPCS, the arguments of functions are passed normally through (R0-R7) registers and the stack pointer is (R13) registers The 8. ARM processor has a total of 37 registers, each of which can be divided into (3) groups according to the different operating modes of the ARM processor. First, fill in the blanks (please answer questions fill in parentheses): a total of 10 items, each item of 2 points out of 20 points. What is the general function of the 6 and R13 registers? stack 1. Generally speaking, the framework of an embedded system can be divided into 4 parts: processor, memory, input / output and software, and the general software is divided into two main parts: operating system and application software. 2, according to the microprocessor used in the embedded system, the embedded system can be divided into (embedded microcontroller), embedded DSP, (embedded microprocessor) and on-chip system. 3, the operating system is to connect hardware and applications of the system program, the basic functions of proc
