Thumb-2 extends the limited 16-bit instruction set of Thumb with additional 32-bit instructions to give the instruction set more breadth, thus producing a variable-length instruction set. A stated aim for Thumb-2 was to achieve code density similar to Thumb with performance similar to the ARM instruction set on 32-bit memory.
AArch64 Instruction Set (A64): The A64 instruction [25] set in the Cortex-R82 provides 64-bit data handling and operations, which improves performance for certain computational tasks and enhances overall system efficiency. [52] Example Instruction: ADD X0, X1, X2 adds the values in 64-bit registers X1 and X2 and stores the result in X0. This 64 ...
This is a list of central processing units based on the ARM family of instruction sets designed by ARM Ltd. and third parties, sorted by version of the ARM instruction set, release and name. In 2005, ARM provided a summary of the numerous vendors who implement ARM cores in their design. [ 1 ]
ARM9 is a group of 32-bit RISC ARM processor cores licensed by ARM Holdings for microcontroller use. [1] The ARM9 core family consists of ARM9TDMI, ARM940T, ARM9E-S, ARM966E-S, ARM920T, ARM922T, ARM946E-S, ARM9EJ-S, ARM926EJ-S, ARM968E-S, ARM996HS.
The ARM Cortex-R is a family of 32-bit and 64-bit RISC ARM processor cores licensed by Arm Ltd.The cores are optimized for hard real-time and safety-critical applications. Cores in this family implement the ARM Real-time (R) profile, which is one of three architecture profiles, the other two being the Application (A) profile implemented by the Cortex-A family and the Microcontroller (M ...
This is a comparison of ARM instruction set architecture application processor cores designed by ARM Holdings (ARM Cortex-A) and 3rd parties. It does not include ARM Cortex-R , ARM Cortex-M , or legacy ARM cores.
An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.
ARM11 is a group of 32-bit RISC ARM processor cores licensed by ARM Holdings. [1] The ARM11 core family consists of ARM1136J(F)-S, ARM1156T2(F)-S, ARM1176JZ(F)-S, and ARM11MPCore. Since ARM11 cores were released from 2002 to 2005 , they are no longer recommended for new IC designs, instead ARM Cortex-A and ARM Cortex-R cores are preferred.
