z80 instruction set

The arm instruction set provides two instructions to directly control the status register (psr,program State Register). The Mrs Instruction is used to transmit the value of the CPSR or SPSR to a register; In contrast, the MSR transmits the contents of a register to CPSR or SPSR. These two instructions are combined to read/write to CPSR and SPSR.Cpsr_c represents

SSE instruction set The SSE (streaming SIMD extensions, single-instruction multi-data stream extension) Instruction Set was first launched by intel in the Pentium III processor. In fact, before piII was officially launched, Intel once published the so-called kni (Katmai new

Thumb Instruction Set The thumb command can be seen as a subset of arm commands in the form of compression. It is proposed for the code density [1] and has a 16-bit code density. Thumb is not a complete architecture and cannot expect the processing program to execute only thumb instructions rather than arm instruction sets. Therefore, the thumb command only need

Some manuals are listed in http://blog.csdn.net/gengshenghong/article/details/7008682, where the Intel intrinsic Guide can query all intrinsic functions, Corresponding assembly instructions and how to use, etc., so, the next is not all analysis, the following only part of the analysis, so as to understand how to use these advanced instruction set in C + + code basic methods, as for more instructions to use,

Instruction Set Y86 Instruction Set Operator: addl, subl, andl, and xorl Jump character: JMP, jle, JL, je, JNE, jge, andjg Condition characters: cmovle, cmovl, cmove, cmovne, cmovge, and cmovg Others: Call, pushl, popl, halt Registers % Eax, % ECx, % edX, % EBX, % ESI, % EDI, % ESP, % EBP The stack pointer has % ESP.

All intrinsic functions, corresponding Assembly commands, and how to use these functions can be queried in the intrinsic guide. Therefore, we will not analyze them all in the following sections, to learn how to use these advanced instruction sets in C/C ++ code, the query manual is easy to understand as to how to use more commands. Note: The commands used below may only involve SSE instruction sets, rather

1 Low-level coloring language TgsiThe OpenGL program uses the GLSL language to program the programmable graphics processor, the GLSL language (the following high-level coloring language refers to GLSL) is a high-level language of syntax similar to C, in the GLSL specification, GLSL language is first translated into the teaching of low-level class assembly language, and then translated into a hardware-specific instruction

0. ARM Registers R13:sp R14:LR 1. Jump Instructions Jump instruction is used to implement the program flow jump, in the ARM program there are two ways to achieve the program flow jump:1) Use specialized jump commands.2) write the jump address value directly to the program counter PC. By writing the jump address value to the program counter PC, you can achieve any jump in the 4GB address space, and use it together before jumping MOV lr,pc such as inst

I. Summary In peacetime project development, may use the third party to provide the static library. A, if the. A provider technology is immature, problems can arise when using it, such as: Compile error on the real machine: No architectures to compile for (Only_active_arch=yes, ACTIVE arch=x86_64, valid_archs=i386). Compile error on Simulator: No architectures to compile for (Only_active_arch=yes, ACTIVE arch=armv7s, Valid_archs=armv7 armv6). To solve these problems, you need to know some detail

The Java Virtual Machine directive consists of a byte length, an opcode (Opcode) that represents a particular meaning, and the following 0 to many operands representing this action parameter. Many of the instructions in the virtual machine do not contain operands, only one opcode. If you ignore exceptions, the JVM interpreter can work effectively with the code. Copy Code code as follows: do{ Automatically compute the PC register and remove the opcode from the PC register locati
