as big as possible, do more to reduce the average thread overhead. However, the GPU is a lightweight thread, and the overhead of the creation and scheduling threads is relatively small. Therefore, we can completely expand the loop, and one thread processes one data. The hardware for parallel programming on GPU is generally called SIMD. Generally, after an instruction is sent, it is executed in multiple ALU units (the number of

In this way, the author interprets "delegation": to pass a method to another method, we need to use delegation. However, I have been thinking about the example of "passing methods to methods" for a long time. This question remains for a long time, and at least seriously affects my thinking and understanding. However, after reading the relevant chapters, I think of an example that I think is very good: Alu. In the R-type command (MIPs),

performed, the carry input is set to 0. When the borrow subtraction operation is performed and the data output of the carry latch is 0 o'clock, the low subtraction results in a borrow, so the accumulator needs to be 1 less, so the carry input is set to 0.The transfer instruction is equivalent to forcing the counter to change the value equal to the transfer address.0 Latch: Input all is 0 o'clock, 0 flag position is 1. The store directive does not affect the zero flag bit. The 0 flag bit can onl

1 What is a GPU1, this PC and ordinary PC is different from the 7 card requires, the lower left corner is the graphics card, in the middle is the GPU chip. The processor of the graphics card is called the Graphics Processing device (GPU), which is the "heart" of the graphics card, similar to the CPU, except that the GPU is designed to perform complex mathematical and geometric calculations.GPU computing power is very powerful, for example: the current mainstream i7 processor floating-point compu

Helloword Program C language code#include void Main () {printf ("helloword\n");}To understand the operation of a Helleword program, the first thing to know is the basic components of a computing system:1. Central Processing Unit CPUIncludes program counter (PC). register file, arithmetic/logic operator (ALU) cacheThe program counter is a word-length storage device (also called a register), and the program counter always points to a mechanical language

Intel X86 Series CPU addressing mode 1 of the history of the first microprocessor chip 4004 is made by Intel. The so-called X86 series, refers to the inte from the 16-bit microprocessor 8086 began the entire CPU chip series. In the X86 series 8086 and 8088 are 16-bit processors, and starting with 80386 are 32-bit processors.2 When we say that a CPU is a 16-bit or 32-bit, it refers to the width of the Alu in the "Arithmetic logic unit" in the processor

through the data bus, the width of the data bus determines the speed of the CPU and the outside world. 8 Data bus can transmit one byte at a time. The 8088CPU data bus width is 8,8086cpu with a data bus width of 16.For example, the CPU wants to write data 89d8 to memory.Because 80,881 times can only transmit one byte of data is 8 bits, so it is divided into two transmission, the first transmission D8, the second transmission 89. However, 8086 has 16 data bus which can transmit two bytes, so the

image above is a computer with some basic hardware components.Some of these hardware require special instructions: 1. Bus : Transfer data between individual parts. 2.I/O device : IO device is the channel that the system communicates with the outside world, such as mouse, keyboard, monitor, disk are typical IO devices. 3. main memory : for short, the processor is used to temporarily store the program and its data when executing the program. Main memory consists of a set of dynamic random memory

: 10000100 Look at the sign bit is 1, is negative, so this number is represented by the complement. First compute the source code. The results of the counter plus 1 are: 01111100 (binary) = 124 (decimal) So the decimal number of the original binary number is-124. calculating the binary complement representation of negative integers To continue with that example, if we get a decimal-124, then what is his binary complement? In fact, his complement is 124 of the binary number of the result of

inline function, then call it will use the function body to replace the function call statement, this will completely eliminate the overhead of the function call. The biggest disadvantage of using inline is that when a function is called frequently, the amount of code increases. 1.2 Processor-related optimized arm method(1) Keep the pipeline smoothAs you can tell from the previous introduction, pipelining delay or blocking will have an impact on the performance of the processor, so you should t

the cost of transmission bandwidth, but also allow the CPU and GPU, the two PCs with the fastest-running components to each other instrumental. The reason is that the processor in the CPU usually has only a few alu, while the ALU in the GPU is much more than the number of CPUs. In addition, the CPU in the cache is relatively large, and the GPU in the cache is much less than the CPU. When necessary, the CPU
