components. Modern CPUs devote a lot of semiconductor area to caches and instruction-level parallelism to increase performance and to CPU modes to support operating...

system. This is generally hardware-enforced by some CPU architectures that provide different CPU modes at the hardware or microcode level. Rings are arranged...

several CPU modes, depending on the implemented architecture features. At any moment in time, the CPU can be in only one mode, but it can switch modes due...

In computer hardware, a CPU socket or CPU slot contains one or more mechanical components providing mechanical and electrical connections between a microprocessor...

a user mode separate from kernel mode involves operating system protection rings. Protection rings, in turn, are implemented using CPU modes. Typically...

Real mode, also called real address mode, is an operating mode of all x86-compatible CPUs. The mode gets its name from the fact that addresses in real...

Common features of Ryzen 1000 desktop CPUs: Socket: AM4. All the CPUs support DDR4-2666 in dual-channel mode. All the CPUs support 24 PCIe 3.0 lanes. 4 of the...

systems in which the CPU should not be disabled for the length of time needed for burst transfer modes. In the cycle stealing mode, the DMA controller...

Addressing modes are an aspect of the instruction set architecture in most central processing unit (CPU) designs. The various addressing modes that are...

inter-process communication (IPC). If the hardware provides multiple rings or CPU modes, the microkernel may be the only software executing at the most privileged...

low-power (idle) mode. The CPU time is measured in clock ticks or seconds. Often, it is useful to measure CPU time as a percentage of the CPU's capacity, which...

computing, protected mode, also called protected virtual address mode, is an operational mode of x86-compatible central processing units (CPUs). It allows system...

run in real mode. After execution passes to an operating system kernel which supports x86-64, the kernel verifies CPU support for long mode and then executes...

A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from...

Support for hierarchical protection domains is typically implemented using CPU modes. Many kernels provide implementation of "capabilities", i.e., objects...

because the routines have different calling conventions, run in different CPU modes or address spaces, or at least one runs in a virtual machine. A compiler...
