ARM1156T2S

The ARM1156T2S is a 32-bit RISC microprocessor core developed by ARM Holdings. It is part of the ARM11 family, which is known for its high performance and low power consumption, making it suitable for a wide range of applications. The ARM1156T2S core is based on the ARMv6 architecture and supports the ARM instruction set, as well as the Thumb instruction set for improved code density and performance.

The ARM1156T2S core features a five-stage pipeline, which includes instruction fetch, instruction decode, execution, memory access, and write-back stages. It also includes a branch prediction unit to improve performance by predicting the outcome of branch instructions. The core supports both little-endian and big-endian data formats and includes a memory management unit (MMU) for virtual memory support.

The ARM1156T2S core is designed to operate at clock speeds up to 600 MHz and can execute up to 1.2 DMIPS/MHz (Dhrystone Million Instructions Per Second per Megahertz). It also includes a hardware divider for improved performance in division operations.

The ARM1156T2S core is commonly used in embedded systems, such as smartphones, tablets, and other mobile devices, as well as in automotive and industrial applications. It is also used in some high-end consumer electronics, such as digital cameras and media players. The core is available as a soft macro, which allows it to be integrated into custom ASICs and FPGAs.
