AMD's Microarchitectures
A microarchitecture describes the physical features, functions, and the technology level of the processes used to manufacture the core of a microprocessor. This article describes the microarchitectures used by AMD. More ...
Operating System Memory Paging
Paging is a memory management scheme that permits a process's physical address space to be noncontiguous. 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 ...
Learn Assembly Language Programming on Raspberry Pi 400
One of the easiest ways to learn assembly language programming is on the Raspberry Pi 400. The Raspberry Pi 400 is a complete personal computer built into a compact keyboard. More ...
The Motherboard Chipset
Because the chipset dictates the bus speed, type and amount of memory, and the type and number of I/O ports, much of a computer's performance is determined by its chipset. 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 ...
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 ...
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 ...
The Android Operating System
Android os is similar to Apple ios in that it is a layered stack of software that provides a rich set of frameworks for developing mobile applications. At the bottom of this software stack is the Linux kernal. More ...
Operating System Process Control Block
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. Although two processes may be associated with the same program, they are considered two separate execution sequences. More ...
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 ...
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 ...
