The Athlon 64 X2 is the first native dual-core desktop central processing unit (CPU) designed by Advanced Micro Devices (AMD). It was designed from scratch as native dual-core by using an already multi-CPU enabled Athlon 64, joining it with another functional core on one die, and connecting both via a shared dual-channel memory controller/north bridge and additional control logic.
It must be noted that not all systems using 16-bit color depth employ the 16-bit, 32-64-32 level RGB palette. Platforms like the Sharp X68000 home computer or the Neo Geo video game console employs the 15-bit RGB palette (5 bits are used for red, green, and blue), but the last bit specifies a less significant intensity or luminance.
Separately, there is a free space map to track free blocks, commonly implemented as a bitmap. [105] Although any free block can be used to store a new file, many operating systems try to group together files in the same directory to maximize performance, or periodically reorganize files to reduce fragmentation .
Version 1.3 was published in February 2011; it includes a new optional Panel Self-Refresh (PSR) feature developed to save system power and further extend battery life in portable PC systems. [88] PSR mode allows the GPU to enter a power saving state in between frame updates by including framebuffer memory in the display panel controller. [ 12 ]
A personal computer, often referred to as a PC, is a computer designed for individual use. [1] It is typically used for tasks such as word processing, internet browsing, email, multimedia playback, and gaming.

Android (all supported versions, as far back as version 4.4 of the Android Open Source Project) has the option to provide a verified boot chain with dm-verity. This is a feature in the Linux kernel that allows for transparent integrity checking of block devices. [306] [307] This feature is designed to mitigate persistent rootkits.
