What is "rhppc"

The RHPPC is a radiation hardened processor based on PowerPC 603e technology licensed from Motorola (now Freescale) and manufactured by Honeywell. The RHPPC is equivalent to the commercial PowerPC 603e processor with the minor exceptions of the phase locked loop (PLL) and the processor version register (PVR). The RHPPC processor is compatible with the PowerPC architecture (Book I-III), the PowerPC 603e programmers interface and is also supported by common PowerPC software tools and embedded operating systems, like VxWorks.
