1.7 We have stressed the need for an operating system to make efficient use of the computing hardware. When is it appropriate for the operating system to forsake this principle and to“waste” resources? Why is such a system not really wasteful?答:单用户系统,它应该最大化地为用户使用,一...
The 'kernel' is the operating system's core, which allows the CPU, memory, graphic card, and other hardware and software to operate as a working computer system. When you turn on the Mac, the kernel starts first. In fact, every program launched on the computer reaches the kernel process ...
Process Control Block (PCB), which is part of the Operating System, aids in managing how processes operate. Every OS process has a Process Control Block related to it. By keeping data on different things including their state, I/O status, and CPU Scheduling, a PCB maintains track of ...
When all you have is a hammer, everything starts to look like a nail. At the end of the day all monitoring systems are data processing pipelines. Sometimes it is more convenient to appropriate part of your monitoring system for another purpose, rather than building a bespoke solution. This ...
CPU Design Historical multicore CPU design has generally used a homogenous CPU topology. That is, all cores are identical. This has the advantage of only requiring the development effort of one core architecture that can be copied and pasted as often as needed. It also makes task scheduling ea...
a cache line is the smallest block of data that can be transferred from main memory to the cpu cache. a cache line typically consists of 64 bytes on a processor with 4-byte instructions, and 128 bytes for 8-byte instructions. whenever the cpu requests data from memory, it fetches the ...
were primarily used for scientific and military purposes. Operating systems were rudimentary, primarily focusing on managing input and output operations. A notable example of this generation is the Electronic Numerical Integrator and Computer (ENIAC), one of the earliest electronic general-purpose ...
图2 Intel Haswell-ECPU 布局 1.2 EDA 是 电子设计自动化 (Electronic Design Automation) 对于怎样把一个VLSI设计塞到一个这么小的面积内,很大程度上是难以用人力实现的,因此我们需要计算机辅助设计(Computer-Aided Design, CAD),通过计算机算法,把输入的VLSI设计,塞到(映射, Map)到带有各种限制的小尺寸芯片内。
