The only difference between opt_calc and naive_calc is that opt_calc has two prefetch commands.
Below are the test functions in C language:
#include
In order to increase the calculation cycle, multiply by 2.
The performance of opt_calc can be increased by about 8% to 20% in Mac Mini CPU p735
Most of the parameters of the Xeon E3 1230 v2 and E3 1230 V3 are the same, such as the core, the number of threads, the main frequency, and so on, but the interface types are different, the former is LGA1150, the latter is LGA1155, which means that
If you only know the concept of CPU, then it is impossible to understand the CPU topology. In fact, in the NUMA architecture, the concept of CPU is from big to small: Node, Socket, Core, Logical Processor. With the development of multicore technology, we encapsulate multiple CPUs together, a package commonly referred to as a socket. Where the physical processor is plugged in, it looks like this: Each core
signed arithmetic operation is either too large or too small to fit into the destination?
Overflow.
9. Which flag is set when an arithmetic or logical operation generates a negative result?
Sign.
10. Which part of the CPU performs floating-point arighmetic?
Floating-point unit.
11. How many bits long are the FPU data registers? How many BITs is the length of the data register of a floating point operation unit?
80bits.
12. Which intel

Specifically, the virtual 64-bit operating system requires enabling Vt In the BIOS. Tip: This host does not support Intel VT-X, so it is impossible to virtualize a 64-bit system.
When prompted: This host supports intel VT-X, but intel VT-X is disabled, you only need to enable the VT function in the BIOS.

The Intel286 processor introduced "protection mode" to IA-32. Protected mode uses the contents of the segment register as a selector or pointer pointer to a descriptor (descriptor) table. Descriptor provides a 24-bit base address, which increases physical memory addressing to 16M bytes (16m=2^24) and supports virtual me
