Abstract
A random number is generated by periodically issuing an operating system call to retrieve values from a number of multiple input shift registers (MISRs) which are coupled to a number of microprocessor buses. The number of MISR readings are then stored in a temporary location, or a number of values based on the MISR readings are stored in a temporary location. A random number is then generated from the stored MISR readings or stored values.
