Why C language (function call) need stack, but assembly language does not need to stack (reprint)

register. So, and above the scene, is a meaning. Save the value of the register, generally with the push instruction, will correspond to the value of some registers, one by one into the stack, the corresponding value into the stack inside, that is, the so-called pressure stack. Then the call to the completion of the child function, and then call the pop, the stack of values, assigned to the corresponding those you just start to press the stack used in the register, the corresponding value from

The earliest SVM was planar and limited in size. But using the kernel function (kernel functions), we can make the plane projection (mapping) into the surface, and then g

The difference between clustering (clustering) and classification (classification) _clustering

2 Classification (classification): Under the existing classification criteria, the new data are divided and classified. Common classification algorithm:Naive Bayesian (Naive Bayes, NB)Super simple, just like doing some number of work. If the conditional independent hypothesis is established, NB will converge faster than the discriminant model (such as logistic regression), so you only need a small amount of training data. Even if the conditional independent assumption is not tenable, NB still b

If the number of parameters is less than or equal to 4, the parameter is composed of r0, R1, R2, r3 registers are passed. If the number of parameters is greater than 4, the parts greater than 4 must be passed through the stack. We will first discuss the situation where the number of parameters is 4.Instance 1:Test_asm_args.asm//---------------------------Import test_c_args; decla

In fact, in the architecture is to refer to the following 10GB/S media Independent interface (Gigabit media independent interface,xgmii), can also be seen as an extension of the XGMII interface. The xgmii is an interface with 74 signal lines, of which 32 data lines are used for sending and receiving data. The xgmii can also be used as the MAC layer of Ethernet to complement PHY. Xaui can also be used to replace the Ethernet MAC layer with the PHY interconnect or as a xgmii ext
