Radiation hardened PowerPC 603eTM based single board computer

Honeywell is developing a product line of standard electronics boards for on-orbit payload processing applications. This product line is based on commercial standards for instruction sets, form factors, back plane busses, I/O and software tools. This architecture is based on a data flow model. The radiation hardened, Single Board Computer (SBC) is based on PowerPC 603e^TM technology licensed from Motorola. The SBC is one building block for realizing a space computing solution. Other building blocks offered by Honeywell are a radiation hardened vector processor (RHVP), mass memory, sensor interface electronics, and I/O suite. The RHPPC SBC provides enough throughput to enable on-board payload processing or can be used for spacecraft control functions. The current generation of space computers is based on R3000 class architectures and offer 20 MIPS performance. The RHPPC SBC offers 222 MIPS performance
