This disclosure describes a method and system that may enable fast, hardware-assisted, producer-consumer style communication of values between threads. The pulper includes a container that is open at the top and has a cylindrical side wall and a driven rotor, which is arranged eccentrically with respect to the center of the container. The servo bursts are first sensed and an upper and a lower threshold values, based on the values of servo bursts, are generated. The entropy data is collected from multiple sources within a computer system and may include data related to a processor in the computer system and an operating system executing on the computer system.
