All the advanced features of the most powerful computers, such as mulicore and parallel processing are done with digital logic. In this article I explain the fundamental concept of digital logic in simple and clear language so that anyone can understand it. More ...
Operating System Memory Paging Hardware Support
Paging is a memory management scheme that involves breaking physical memory into fixed-sized blocks and breaking logical memory into blocks of the same size called pages. When a process is to be executed, its pages are loaded into any available memory blocks. 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 ...
Intel's Sandy Bridge Micro-Architecture
"Sandy Bridge" is Intel's code name for a new cpu core microarchitecture. It introduces a few new or improved features. The memory controller, the PCI Express controller, and video circuitry are all located within the processor die and the new ring architecture uses a Last Level Cache between the CPU and graphics cores. More ...
Shortest-Job-First 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 shortest-job-first scheduling. More ...
Expanding the Resources of Microcontrollers
In some cases it is possible that the internal resources of a microcontroller are insufficient. The solution to these situations is to add external components by creating an expanded microcontroller structure. More ...
Pentium P5 Processor
The Pentium P5 processor was introduced in 1993 was the first superscalar processor. It featured two integer pipelines and a pipelined floating-point unit. This article describes other innovations introduced in the P5. More ...
Intel Celeron D Processor
The Celeron processor is a budget processor offering moderate performance at an affordable price. The Celeron processor is suitable for use in notebook and desktop computers running home-office applications and providing access to the Internet. More ...
Operating System Processes
An Operating System Process is a program in execution. It includes the value in the program counter and in the processors registers. A process also includes a stack, data section, and a heap. More ...
The Microcontroller Memory Map
a microcontroller is a set of resources. Each resource is identified by one or more addresses in an address space. The memory map is a graphic representation of how the resources are associated with addresses. More ...
