Abstract
A multi-buffering apparatus in a random number generator. A microprocessor includes a random number generator that employs multiple buffers for buffering random data bytes generated by the generator. The apparatus maintains a first selector for selecting one of the buffers as the current buffer for filling with generated bytes. When the current fill buffer becomes full, the apparatus updates the first selector to a different buffer and continues the process until all buffers are full. The apparatus maintains a second selector for selecting one of the buffers as the current buffer for supplying random data bytes to an application. When the current supply buffer becomes empty, the apparatus updates the second selector to a different buffer and continues the process until all buffers are empty. The apparatus can concurrently fill the buffer selected by the fill selector and supply data from the buffer selected by the supply selector.
