The following is a list of ARM-based System-on-Chips (SoCs) that either have been used in RISC OS machines, or are potentially suitable for RISC OS machines.


Samsung S3C24xx

Based on ARM9 cores. The only member of this family that is relevant to RISC OS is the S3C2440, based on the ARM920T core.

Used in

Compatible with

  • RISC OS Adjust32 4.4x

Ankya AK7802

Based on ARM926EJ core, clocked at 248 or 266 MHz. Used in some cheap netbooks, but not suitable for RISC OS applications due to poor performance relative to more suitable SoCs.
