Abstract Digital computer selection for spacecraft applications is not as big of a problem as it used to be, because computers have increased in speed and in the size of their memories. Thus, these are no longer major factors in the selection process. However, radiation hardness, sensitivity to SEU, power consumption and I/O capabilities are still properties that influence the choice of digital processors. A list of factors that should be taken into consideration is given below: Architecture (one central or a distributed set of computers) Software Operating System Instruction Set Number of Bits Per Word I/O Capability Rad Hardness Reliability Redundancy Memory Size Speed Cost Weight Power Consumption
