Released in June 2009, revision 4.0 of the ACPI specification added various new features to the design; most notable are the USB 3.0 support, logical processor idling support, and x2APIC support. Initially ACPI is exclusive to x86 architecture; Revision 5.0 of the ACPI specification was released in December 2011, [15] which added the ARM ...
Since 1995, various versions of the ARM Architecture Reference Manual (see § External links) have been the primary source of documentation on the ARM processor architecture and instruction set, distinguishing interfaces that all ARM processors are required to support (such as instruction semantics) from implementation details that may vary ...
This is a list of products using processors (i.e. central processing units) based on the ARM architecture family, sorted by generation release and name.
Arm today announced Armv9, the next generation of its chip architecture. Its predecessor, Armv8, launched a decade ago and while it has seen its fair share of changes and updates, the new ...
Most chips support the 32-bit ARMv7-A for legacy applications. All chips of this type have a floating-point unit (FPU) that is better than the one in older ARMv7-A and NEON ( SIMD ) chips. Some of these chips have coprocessors also include cores from the older 32-bit architecture (ARMv7).
Variation between ARM-based hardware platforms has been an impediment requiring operating system adjustments for each product. The SBSA seeks to strengthen the ARM ecosystem by specifying a minimal set of standardized features so that an OS built for this standard platform should function correctly without modification on all hardware products ...
Given the correct device tree, the same compiled kernel can support different hardware configurations within a wider architecture family. The Linux kernel for the ARC, ARM, C6x, H8/300, MicroBlaze, MIPS, NDS32, Nios II, OpenRISC, PowerPC, RISC-V, SuperH, and Xtensa architectures reads device tree information; on ARM, device trees have been mandatory for all new SoCs since 2012.
