8051 instruction set

Computer Systems A Programmer ' s perspective Second EditionWe have seen a processor must execute a sequence of instructions,where each instruction performs some primitive operation, such as addingThe numbers. An instruction are encoded in binary form as a sequence of 1 or more bytes.The instructions supported by a particular processor and their byte-level encodingsis known as its

Instruction Set section. 7. Data packaging and data shuffling commands Key points: 1. The data packaging and rescheduling commands of sse2 are exactly the same as those of MMX data packaging and shuffling commands on the command mnemonic. 2. The arithmetic operation commands of sse2 operate on the 128-bit XMM registers, while the MMX commands operate on the 64-bit mm registers. 3. In case of me

In the llvm gcc4.2 compiler, Apple uses the prompt interface in xcode to explicitly provide programmers with options for compiling the target code into arm. In Apple llvm3.0, this option is missing. Because the apple A4/A5 processor using the armv7a architecture has the thumb-2 instruction set, the thumb Code further improves the computing capability while ensuring the closeness. Therefore, Apple sets the

# G ++-wall-March = pentium4-mmmx ft. cpp-o ft-lpthread An error occurred while compiling on a 64-bit machine: Error: CPU you selected does not support x86-64 Instruction Set The CPU you selected does not support the x86-64 instruction set, solution, modify the march Value March = x86-64, different systems may not

ARM Instruction Set I. Classification and format of microprocessor commands ARM's unprocessed instruction sets can be divided into Jump commands, data processing commands, program status registers (SRS) processing commands, loading/storage commands, coprocessor commands, and abnormal generation commands, the specific commands and functions are shown in the foll

Introduction to bytecode instruction set:The instructions for a Java Virtual machine consist of a byte-length opcode that represents the meaning of a particular operation (Opcode) and 0 to several operands (operands) that represent the parameters required for this operation. Many instructions in a virtual machine do not contain operands, only one opcode. Do { automatically calculates the PC register and removes the opcode from the location of the PC

Set the name and password of the WiFi module (AP mode)At+cwsap= "ESP8266", "1234567890", 5,3 This module can operate in three modes: 1. STA 2. AP 3. Ap+sta, factory set to the third type STA mode: Station, similar to the wireless terminal, the STA itself does not accept wireless access, it can connect to the AP, the general wireless network card is working in the mode. At+cwmode=1/2/3 The following is an ex

The SSE instruction set is introduced on the Internet. Here we post a SSE test program in the vs2008 environment, which is compiled in C ++ code and C ++ inline, c ++ SSE intrinsics three methods of convolution calculation program... this is a Win32 console program .....

Here we will briefly describe several important arithmetic operation commands. 1. Horizontal addition command The ssse3 Instruction Set adds commands that add integers horizontally, similar to the floating point commands of sse3. Phaddd Add a 32-bit unsigned integer in the horizontal direction of the Register Phaddw Add the registers horizontally according to the unsigned 16-bit integer

MRS and MSR InstructionsThe status flag in the MRS (move PSR to general-purpose Register) procedure status register (program state REGISTER,PSR) is read into the Universal Register, MSR (move general-purpose Register to PSR) writes the flag to the program status register. These two instructions can be used in the current program status register (CPSR) or in the Saved program status register (SPSR). For example:MRS R0, Cpsrmrs R1, SPSRMSR PSR, R7BIC directivesThe BIC is used to place the specifie
