PCI, CPCI, cpcieDifferences and features
CPCI bus
• As a local bus of the processor system, the PCI bus is designed to connect external devices, rather than the system bus used as the processor, to connect the cache and primary storage.
• (1) PCI bus space and processor space isolation
• (2)ScalabilityBridge
• (3)Dynamic configuration mechanism plug-and-play
• (4)Bus bandwidth
• (5)Shared bus Mechanism

Integer constants.
Pci can be changed to point to different non-Integer constants.
You can describe pci to read data.
You cannot describe pci to modify the data it points.
Note: The data type and the order of const are irrelevant and can be exchanged.
Const int * pci = int const * pciConstant pointer to a very large number
The pointer is immutable, but the data it points to is variable.
int num;int *const cpi = num;
If you initialize cpi to point to the constant limit, an error will occur b

Recently, CPCI was used in the project, and the information about PCI was collected online. CPCI is a subset of PCI. The bridge chip used is divided into two types: master and slave. As for PCI, I will describe it as follows:

First, we need to clarify several terms: const pointer and pointer to output:
A const pointer is a pointer that has a constant worth it. It does not include any hint of "whether it is a constant.Const char * PCI; // pointer to a constantChar * const CPI = 0; // constant pointerChar const * pci2; // still a pointer to a constantConst char * const CPCI = 0; // constant pointer to a constant.Char * IP; // common pointer

Now point to the variable:
int II = 2;
const INT *PCI =ⅈ
Similarly, you cannot assign values after you dereference PCI, but you can assign values directly to the II.
Here Comes the!!!.

Review: Pointers are objects, and references are not.
The const pointer means that the pointer object itself is a constant, allowing the pointer itself to be defined as an object.
Effect: The const pointer cannot change the address to the object.

The following is a Linux and socket chat program I recently studied using C. To learn epoll, epoll has a lot of socket statements, so it jumps to the C side.

In addition, I recently read "C and pointer" and read it intermittently. Record an interesting one today
For Constants
Int const;
Const int;
Both statements are normative.
Int * PI; Pi is a common pointer to an integer.
Int const * CPI; PCI is a pointer to an integer constant. You can modify the
the support capability of testing tools for Embedded operating systems, such as DOS, VxWorks, neculeus, Linux, and Windows CE; on the other hand, we also need to consider the hardware platform support capabilities of the testing tool, including whether all 64/32/16-bit CPUs and MCU are supported, and whether the PCI/VME/CPCI bus is supported.
