ARM11
ARM11 is a product family announced in 2002, featuring the ARMv6 architectural additions including SIMD media instructions and multiprocessor support. It gained popularity for its use in smartphones from companies like Apple and Nokia. The initial ARM1136 core was released to licensees in the same year, showcasing advancements over the previous ARM9 generation.
ARM11 cores differentiate themselves by incorporating ARMv6 instructions for media support, along with microarchitecture improvements. They feature physically addressed cache, support for unaligned and mixed-endian data access, and various core options such as ARM1136, ARM1156, ARM1176, and ARM11MPcore. Each core iteration introduced enhancements like Thumb2 instructions, security extensions, and multicore support.
Notable chips utilizing ARM11 cores include the Broadcom BCM2835 in the Raspberry Pi B+, Atheros AR7400, and STMicroelectronics STA2065N2 with embedded GPS. Various other manufacturers like Ambarella, ASPEED, Broadcom, Cavium, CSR, and Freescale have also integrated ARM11 cores in their chip designs. For further information, ARM provides official documents, Architecture and Core Reference Manuals, Quick Reference Cards for instructions and opcodes, and details on ARMv8.x-A architectures and compatible processors.
