32 × 128-bit registers [1] for scalar 32- and 64-bit FP or SIMD FP or integer; or cryptography AArch64 or ARM64 is the 64-bit Execution state of the ARM architecture family . It was first introduced with the Armv8-A architecture, and has had many extension updates.
The processor state can change on an Exception level change; this allows 32-bit applications to be executed in AArch32 state under a 64-bit OS whose kernel executes in AArch64 state, and allows a 32-bit OS to run in AArch32 state under the control of a 64-bit hypervisor running in AArch64 state.

This is a table of 64/32-bit central processing units that implement the ARMv8-A instruction set architecture and mandatory or optional extensions of it. Most chips support the 32-bit ARMv7-A for legacy applications.
Computer architectures are often described as n-bit architectures. In the first 3 ⁄ 4 of the 20th century, n is often 12, 18, 24, 30, 36, 48 or 60.In the last 1 ⁄ 3 of the 20th century, n is often 8, 16, or 32, and in the 21st century, n is often 16, 32 or 64, but other sizes have been used (including 6, 39, 128).
Over time, the PE format has grown with the Windows platform. Notable extensions include the .NET PE format for managed code, PE32+ for 64-bit address space support, and a specialized version for Windows CE. To determine whether a PE file is intended for 32-bit or 64-bit architectures, one can examine the Machine field in the IMAGE_FILE_HEADER. [6]

The second generation Tegra SoC has a dual-core ARM Cortex-A9 CPU, an ultra low power (ULP) GeForce GPU, [17] a 32-bit memory controller with either LPDDR2-600 or DDR2-667 memory, a 32 KB/32 KB L1 cache per core and a shared 1 MB L2 cache. [18] Tegra 2's Cortex A9 implementation does not include ARM's SIMD extension, NEON. There is a version of ...
The ARM Cortex-A is a group of 32-bit and 64-bit RISC ARM processor cores licensed by Arm Holdings.The cores are intended for application use.
