Dual-core CPU Unknown three facts

Today, the hype about dual-core processors is so widespread that the understanding of the technology seems to be out of the truth. Both AMD and Intel compliment the merits of their dual-core processors on their web pages. Their campaigns are timely, as most industry watchers believe the dual-core processors will be in the pipeline in 2006. But there are some st

Server Technology Fundamentals

server has a wide range of CPUs, including RISC and CISC architectures, and PCs typically have only CISC ? servers tend to have multiple processors, while PCs usually have only 1 Memory ? The server memory slot is far more than the PC, generally more than 8, PC often less than 4 ? The server uses ECC, registered, Chipkill, hot spare, image and other technologies to ensure the reliability of the data, the PC basically does not ? server

(Multi-Core DSP QuickStart) 7. Using Sharedregion for inter-core memory sharing

the amount of time to configure Sys/bios. The examples in this article do the following tasks: (1) Core 0 creates shared memory, writes data to memory, and then sends the memory address to the slave kernel via notify. (2) receive the kernel 0 notification from the core (1 to 7 cores), open the memory address, and read the data. (3) completed.second, import sharedregion module Sharedregion module is IPC from the name can be seen, it is a shared area, especially for multiprocessor environment

factors when choosing a processor and choose a CPU that meets the above requirements.D. What interface do I need to use between the system and other external devices? Explanation: This is also a critical issue to evaluate the processor, and choosing a processor with these interface capabilities will facilitate our circuit design and software programmingE. Is it possible to make changes after the design is complete, or is the system requirements likely to change during the design process? Does o

Intel64 and IA-32 Architecture Optimization Guide Chapter 1 multi-core and hyper-Threading Technology-8th Memory Optimization

8.6 Memory Optimization Efficient Cache operations are a key aspect of memory optimization. Note the following points for Efficient Cache operations: ● Cache parts ● Shared storage Optimization ● Eliminate 64 K bytes of overlapping data access ● Prevent excessive L1 cache eviction 8.6.1 cache Partitioning technology Cyclic partitioning is useful for reducing cache failures and improving memory access performance. When the cyclic block technology is applied, it is critical to select a proper bloc

Dual-core processor

to the CPU to eliminate system architecture challenges and bottlenecks. The two processor cores are directly connected to the same kernel, and the core communicates with each other at chip speed, further reducing the latency between processors. Intel shares the frontend bus with multiple cores. Experts believe that amd architecture is more likely to achieve dual-core or multi-core, Intel architecture will encounter Bottlenecks of multiple kernels com

Intel System Programming Guide Chapter 1-11th memory type range register (mtrr)

The following sections only apply to P6 and the updated Processor family. The memory range register (Note: plural) provides a mechanism for associating the memory type (see section 11.3) with the physical address range in the system memory. They allow processors to optimize operations for Different Storage types, such as Ram, Rom, frame cache memory, and memory ing I/O devices. They also simplify system hardware design by eliminating memory control p

Basic Structure of Windows NT kernel

Windows NT, you can also write drivers that do not control the device. Even file systems are loaded as drivers.Another example of Windows NT scalability is the implementation of system call interfaces. To modify operating system behaviors, developers generally need to hook up or add system calls. The development team of Windows NT has a good system call interface to easily hook up and add system calls. However, Microsoft still does not disclose these mechanisms. Compatibility (compatibility) Fo

you have to explain the cause in the meeting. In short, never let it happen. So what about multiple processors? My mean value is 3.00, but the system is running normally! Wow, you have four processor hosts? Therefore, the average load is 3.00. In a multi-processor system, the average load is determined by the number of kernels.
