Intel's Core i7 Processors
Core i7 is a family of Intel quad core processors, that is, they have four processors on a single silicon chip. All four processor cores and all memory caches, including a 64K L1 cache, a 256K L2 cache, and a shared L3 cache are located on one chip. The memory is also located on the same chip. More ...
The AMD Athlon 64 X2 Processor
The Athlon 64 X2 is the first dual-core CPU manufactured by AMD.
It is essentially two Athlon 64 cores on one die joined together with additional control logic. The cores share one dual-channel memory controller. The benefit of dual-core processors is their ability to process more software threads at the same time. However, many programs are written with only one thread. More ...
Computer Buses
A 16-bit bus can transfer 16 binary bits simultainiously. This requires 16 separate metal traces on a PC board. We also need traces for control signals. The whole group of traces is referred to as a bus. More ...
Microcontroller Architectures
The fundamental microcontroller architectures are Von Neumann and Harvard. More ...
The Microcontroller's Asynchronous Serial Interface
An Asynchronous Serial Interface sends data one bit at a time, as apposed to a parallel interface which send one byte or one word at a time, and asynchronous means it sends them when its ready, without reference to a clock signal. More ...
Multi-Processor Scheduling
Here, we discuss several concerns in multiprocessor scheduling in the context of Multicore, Multithreaded core, NUMA (Non-uniform memory access), and Heterogeneous multiprocessing architectures. More ...
Microcontroller Internal EEPROM (Electrically Erasable Programmable Read Only Memory) Memory
In some situations it is required that some program parameters such as configuration settings be keept after the system is powered off. This is made possible by including a EEPROM internally to the microcontroller. More ...
First-Come, First-Served CPU Scheduling Algorithm
CPU Scheduling deals with the problem of deciding which of the processes in the ready queue is to be alocated the CPU. There are many different CPU scheduling algorithms. In this article we describe first-come, first-served scheduling. More ...
Electronic Circuits Basics
This article's main target is to teach the electronics language to readers that are not familiar with electronics by using a group of rules and simple equations that describe the behavior of every electronic component and the relationship between the components in the circuit. More ...
Operating System Memory Protection in a Paged Environment
Memory protection in a paged environment is accomplished by protection bits associated with each frame. For example read-write, read-only or execute-only bit, and valid-invalid bit. Normally, these bits are kept in the page table. More ...
Windows Operating System Services, Functions, Routines, Processes, Threads, and Jobs
The Windows operating system uses many confusing terms. This article explains the meaning of the terms: Services, Functions, Routines, Processes, Threads, and Jobs. More ...
Introduction to Computer System Main Memory Operation
The CPU can be shared by a set of processes. Using CPU scheduling, we can improve the utilization of the CPU and the speed of the computer's response. To realize this increase in performance, multiple processes must be kept in memory. More ...
