Abstract
As a component in a vital processing system, the vital driver includes hardware and software elements that enable it to produce a time sensitive output in response to receipt, on a batch basis, of check words. The number, content and rate of the check words are checked and used by the vital driver to produce a time sensitive output which can have parameters such as carrier frequency, modulation rate and duty cycle which are determined in part by the number, content and rate of receipt of the check words, and in part by the flawless execution of its own software. The vital driver software includes a number of significant elements including a vital starting delay, as well as modular components for producing different portions of the time sensitive output. Because of its modular nature, the software allows the production of an identical time sensitive output from groups of check words which are different in number and content, enabling the same vital driver to perform a checking function on primary processors which are running significantly different software.
