1.2.2 Main Board
1.2.2.1 CPU: Intel StrongARM SA1110-206MHz
The SA-1110 is a general-purpose, 32-bit RISC microprocessor with a 16 Kbyte instruction cache, an 8 Kbyte
write-back data cache, a minicache, a write buffer, a read buffer, and a memory management unit (MMU)
combined in a single chip. The SA-1110 is software compatible with the ARM * V4 architecture processor family
and can be used with ARM * support chips such as I/O, memory, and video.
