Overview
Available with the PowerPC MC7448 RISC CPU with integrated L2 cache, running at
up to 1.4 GHz, the IMP2B is based around a Marvell Discovery V (MV64560)
Integrated System Controller, which combines high performance system control
with multiple communication peripherals including high speed serial and dual
Ethernet ports, all on a single chip.
