    Opencores has a ARM compatible 32bit processor core called Amber. But it uses ARM v2a ISA which is pretty old. According to below slides (page 35), v2a is used on ARM2as and ARM3. According to amber intro, v2a is adopted because 1. not covered by patent 2. still supported by GNU toolchains.

    Anyone is using this core? I am concerned it may not worth the efforts. Maybe I should use CM0?
