Windows CE supported the Hitachi SuperH-3 and SuperH-4 processors. These were commonly abbreviated SH-3 and SH-4, or just SH3 and SH4, and the architecture series was known as SHx.
I’ll cover the SH-3 processor in this series, with some nods to the SH-4 as they arise. But the only binaries I have available for reverse-engineering are SH-3 binaries, so that’s where my focus will be.
Another architecture series by Raymond Chen, diving into some deep details about the SHx architecture.
