undoubtedly a good solution in Multi-Service routers. In addition, all users put QoS first in terms of support for PoE, QoS, MPLS and IPv6. Indeed, the core of multiple businesses is to differentiate the types of businesses, and then provide corresponding policies based on different businesses to allocate different service quality. As said Wu Jianxin, Cisco ISR product manager, "QoS is critical and quality of service must be allocated to each applica

Interrupts are an important part of an embedded system, but no interrupts are included in standard C. Many compiler developers have added support for interrupts on standard C, providing new keywords for marking interrupt service programs (ISR), similar to __interrupt, #program interrupt, and so on. When a function is defined as an ISR, the compiler automatically increments the interrupt field into the stack

system analysisUCOS-II Interrupt Service Program (ISR) is generally written in assembly language. The following are the steps for interrupting a service program. Save all CPU registers, call Osintenter () or osintnesting (global variable) directly plus 1; Execute user code to do interrupt service; Call Osintexit (); Recover all CPU registers; Executes an interrupt return instruction. The UCOS-II provides two

. You can also initialize data transmission from another device to another device.Devices that rely on the IO manager to queue Device Requests. Io manager serializes IRPs to ensure that the driver processes only one IRP at a time. most drivers process multiple IRPs at the same time, but serialization is reasonable for some drivers, such as keyboard drivers. An interrupt service routine (ISR)-When a device is interrupted, the kernel interrupt distribu

) structures. An add-on device routine:This function is named adddevice and is called by the I/O manager, whenever a new device, for which the driver is responsible, is detected. it is used by the driver to initialize the device object (I. e. the internalStructure) that corresponds to the newly-found device. A set of dispatch routines:These are the functions that are called by an application (or another driver) to communicate with the device. they include functions like read, write, open, clos

service is not available, because no specific interrupt handler is executed. The real interrupt service will only occur after the discontinuing handler ISR is attached to an interrupt request queue by the initialization program of a specific device. 3. The IDT must be properly initialized before interruption is permitted. 7. Activation interruption or exception (the following content is automatically completed by the hardware) 1.

any time, after a period of time can be run, the corresponding data will not be lost; reentrant functions use only local variables, which are stored in the CPU registers or stacks, and are protected with global variables; Non-reentrant features: Using the Malloc/free function, the malloc function manages the stack with a global list; Calling standard I/O library functions, many implementations of standard I/O libraries use global data structures in a non-reentrant manner;

an integer variable with an absolute address of 0x67a9. The compiler is a purely ANSI compiler. Write the code to complete the task.This question tests whether you know that in order to access an absolute address it is legal to cast an integral number (typecast) as a pointer. The way this problem is implemented varies with individual style. A typical similar code looks like this:int *ptr;PTR = (int *) 0x67a9;*ptr = 0xaa55;A more obscure approach is:One of the more obscure methods is:* (int * co
