METHOD AND APPARATUS FOR A REDUNDANCY APPROACH IN A PROCESSOR BASED CONTROLLER DESIGN

摘要

A system (20) for handling data of a process with a primary controller (30) and a redundant controller (40). The primary controller (30) includes a primary processor that is operable to perform tracking data tasks by using a low speed bus to cooperate with a tracker controller (32) for storage of tracking data in a tracker memory. The primary processor is further operable to perform other tasks by using a high speed bus in cooperation with a primary memory (32). The second bus (37) has an operating rate considerably higher (for example, a factor of two or more) than that of the first bus (38).
