Macro can be used to implement custom directives, by using custom directives, you can define a section of a template fragment as a user instruction, using the macro instruction syntax in the following format:.........In the above format fragment, the following sections are included:The Name:name property specifies the name of the custom directive and can pass in multiple parameters when using a custom direc
Features:Load/Store Structure (memory operations only include load and store, and all other operations are completed in registers)32-Bit fixed instruction width3. Address Instruction format (both source operands and result registers are specified independently)Each Command is executed in a condition.A normal operation and a normal ALU operation can be completed simultaneously in a single
MMX technology OverviewIntel's MMX #8482; (Multimedia enhancement Instruction Set) technology can greatly improve application processing capabilities for 2D and 3D graphics and images. Intel MMX technology can be used for complex processing of large amounts of data and complex arrays. The basic units of data that can be processed using MMX technology can be byte, word ), or double-word ).Visual Studio. NET 2003 provides support for MMX
: After the above program is executed, the value in ax is 1, because after JMP short S is executed, the value of add ax, 1 is crossed, and the IP points to the INC ax at S. That is to say, the program only performs one AX plus one operation. Note: What are the machine commands corresponding to N Assembly command JMP short s? N let's take a look at other Assembly commands and their corresponding machine commands. As you can see, in a general assembly instr
vertices have been output, the GS program ends. No location or parameter is output. 7. The DC program reads vertex data from the GS ring cache and uses a mem _ * Memory output command to transmit the data to the parameter cache and location cache. 8. The DC program exits and the r700 releases the GPR space. 9. The PS program is running. 10. Data assembly elements in the r700 from-location cache, parameter cache, and VGT. 11. The hardware performs scan conversion and final pixel interpolation, a
principle of computer composition--Instruction line 1. OverviewTo improve CPU utilization and speed up execution, the instructions are divided into phases that can execute different stages of different instructions in parallel, so that multiple instructions can be executed simultaneously. In the case of effectively controlling the pipeline congestion, the pipeline can greatly improve the speed of instruction
Problems in Arm assemblyArm assembler is similar to x86 assembler. Use ";" to comment. Such as start and loop. ENTRY indicates the start of the program, and END indicates the END. Of course, these two must be written in alignment.The following describes the first arm assembler I wrote. It deserves to be a difficult problem. I think this code can be viewed as a new handwriting. The Line "Stop B Stop". However, even such a line of code is hard to produce.In the first arm assembly code, I did not a

Recently encountered in the project requires nested directives, instructions in the nested sub-instructions must obtain the data in the parent instruction to judge, but in the writing of the parameters encountered a pit, so record, to prevent later forgotten, personal superficial understanding, welcome message to discussFirst of all, the scope binding scope of Directive on the network already has a lot of, nothing is the scope of the three kinds of bi

The previous "Angularjs Primer 3--html's hands-on instruction" introduced the concept and function of the directive. Already and instructions have played a face-to-face, it will not be so strange, today is mainly introduced is a troubled me for a long time finally figured out the problem, this problem with scope , can be regarded as the "Angularjs Introductory experience Directive and controller how to communicate "in the scope of the supplement and e
, no need to find Icache. Read directly from memory and, conversely, assume that the value of Icqmem_ci_o is 0, and first find it in Icache.(3) The interface name between Icache and Wb_biu is in the form of icbiu_xxx_x, and the interface name between Icache and Qmem is in the form of icqmem_xxx_x, so the location of the interface can be known by name.12.3.2 Data section of IcacheThe data portion of the Icache contains Ic_tag, Ic_ram, and its main body is a one-port RAM.The two together make up t
B or BL instruction causes the processor to transfer to the "subroutine name" to begin execution. The difference between the two is that the BL instruction copies the address of the next instruction to the R14 (LR, link register) before it is transferred to the sub-program execution. Since the BL instruction saves t
maintained within the JVM thread, meaning that the order of execution of the instructions may not be consistent with the order of the Code as long as the final result of the program equals the result of its strict sequential environment. This process is done by reordering called directives. The meaning of command reordering is that the JVM is able to properly reorder machine instructions based on the characteristics of the processor (multi-level cache system, multi-core processor, etc.), so tha
"AngularJS" 5 examples of detailed directive (instruction) mechanismThis article has organized and expanded the contents of the sixth chapter of the book "AngularJS", which will be published by the electronic industry press recently, please expect password: Angular1.

Machine Word Length: The number of bits that the CPU can process data at a time, usually related to the number of registers of the CPU.Storage Word Length: The number of bits of binary code stored by a storage unit (storage address) in memory, that is, the number of MDR in memory.Instruction word Length: The number of bits of the computer instruction character.Data word Length: The number of bits occupied by the computer data store.Note: von Neumann m

The transfer-fill Command sends the source operation with a short number of digits to the destination operand with a long number of digits. The command format is as follows: Movsx/movzx REG/MEM, Reg/MEM/Imm; 80386 + Among them: 80386 + indicates the CPU of 80386 and later. Other Similar symbols have similar meanings and are not described. The main functions and restrictions of commands are similar to those of mov commands. The difference is that the high level of the destination operand is
