Tiny Linux camcorder runs ARM-no-MMU Linux

Jan 26, 2005 — by Henry Kingman — from the LinuxDevices Archive

Samsung used uClinux and an ARM9-based SoC to build a tiny, high-quality diskless camcorder that doubles as a digital camera, mp3 player, voice recorder, data storage device, and web cam. The Miniket runs a 2.6-series “ARM-no-MMU” uClinux kernel that can boot to a shell in 80msec.

A whitepaper by the Miniket's system architect, Hyok Choi, is also available. The paper describes the rationale for using uClinux rather than Linux on ARM9 processors with MMUs (memory management units):
