Intel's Core 2 Processors
Intel's Core 2 processors, released in July of 2006, are based on the Core microarchitecture, a dual core design using a 65nm manufacturing process to put 291 million transistors on a 143 square mm die. Each core has its own 64KB L1 cache. The two cores share an L2 cache that can be either 2MB or 4MB. More ...
Monolithic Kernel vs Microkernel vs Hybrid Kernel
An operating system consists of two parts, the kernel space which operates in privileged mode, and the user space which operates in unprivileged mode. 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 ...
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 ...
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 ...
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 ...
How Computer Chips are Made
The oxygen is removed from silica by heating it with carbon. A tiny seed of silicon is then dipped into molten silicon. As the tiny crystal is slowly lifted out of the crucible silicon crystallizes around it. More ...
Load Balancing Multiple CPUs in Symmetric Multiprocessing
On Symmetric Multiprocessing (SMP) systems it is important to keep the workload balanced among all processors. There are two approaches to accomplish this, push migration and pull migration. More ...
Basic Computer Architecture
Basic computer architecture refers to the structure of a computer system and comprises its hardware, firmware, and software. Hardware consists of the physical components in computer architecture. The main hardware components of the computer architecture include the CPU, memory, and bus. 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 ...
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 ...
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 ...
