Integrated Circuit Design Flow
The process of integrated circuit design can be divided into stages: system design, logic design, circuit design, layout design, fabrication and testing. More ...
Operating System Process Management
A program is not a process. A program is a file containing a list of instructions stored on disk. A process is an active entity with a program counter specifying the next instruction to execute and a set of resources. A program becomes a process when an executable file is loaded into memory. 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 ...
Basic Electronics for Computer Architecture
To understand computer architecture, it is necessary for you to have a basic understanding of electronics. This article explains how all the amazing things that can be done with electronics are the result of one simple thing - electric charge. More ...
Digital Logic Transfer Characteristics
In the real world, gates don't transfer logic levels instantaneously. The time it takes for electrons and holes to move through the semiconductor material (called propagation delay) in CMOS are less than 100 ps (pico seconds), but there are other delays caused by resistance, capacitance, and inductance. More ...
CPU Process Scheduling
CPU scheduling is the basis of multiprogrammed operating systems. By switching the CPU among processes, the operating system can make the computer more productive. More ...
Microprocessor Registers
To a large extent the operation of a microprocessor involves loading, transferring, and manipulating the contents of registers. In this article you learn about the functions, and purposes of the register set of the Intel 8086 microprocessor. More ...
Microprocessor Counter, Clock, Timer Circuits
All the circuitry in the microprocessor, in fact all the circuitry on the motherboard require a clock signal for operation. The clock signal is the heartbeat of the system. Without a clock signal, the microprocessor and the computer are dead. More ...
Microcontroller Registers
Registers are special small memory locations where the microcontroller can write data to or read data from. Special function registers help point to main memory locations, indicate the result of a mathematical operation, hold parts of an instruction or indicate the status of some operation or hardware feature. Some registers are general purpose and may be used by the programmer at their own discretion. More ...
Operating System Memory Allocation Methods
Operating System Memory Allocation is the process of assigning blocks of main memory to various running processes and to move processes back and forward between the main memory and disk. More ...
The AMD Athlon 64 Processor
AMD's Athlon 64 processor, released in September 2003, was their first 64-bit processor targeted for the workstation market to compete with Intel's Pentium 4. AMD's first 64-bit processor was the Opteron, released earlier in April that same year, targeted for the server market to compete with Intel's Xeon processor. More ...
Intoduction to Digital Electronics
The entire field of computer technology relies on transistors. This article describes how transistors are constructed and how modern MOSFETs are combined to make digital logic circuits. More ...
