Abstract: A system receives data in multiple streams from an upstream device. The system temporarily stores the data in a first buffer and asserts a forward flow control signal when a capacity of the first buffer exceeds a first threshold value. The system reads the data from the first buffer and selectively processes the data based on the forward flow control signal. The system temporarily stores the selectively processed data in a number of second buffers, generates a backward flow control signal when a capacity of one of the second buffers exceeds a second threshold value, and sends the backward flow control signal to the upstream device.

Abstract: A servomechanism controller for controlling the movement and positioning of a servomechanism (such as that of an actuator assembly for the read/write heads of a hard disk drive assembly) in accordance with an improved "bang-bang" seek technique includes at least one neural network. In one embodiment, a single neural network, connected to a plant with servomechanism, receives two input positioning signals and provides an output positioning signal. One input positioning signal represents a desired servomechanism position, while the other represents its present position. The output positioning signal represents a positioning time period within which the servomechanism will reach the desired position plus a deceleration time period within the positioning time period upon the termination of which the servomechanism will reach its desired position. In another embodiment, one neural network, connected to the plant, receives an input positioning signal and provides an output positioning signal and a status signal.
