Abstract: A method of programming a programmable analog device that introduces on a single chip a set of tailored analog blocks and elements that can be configured and reconfigured in different ways to implement a variety of different analog functions. The analog blocks can be electrically coupled to each other in different combinations to perform different analog functions. Each analog block includes analog elements that have changeable characteristics that can be specified according to the function to be performed. Configuration registers define the type of function to be performed, the way in which the analog blocks are to be coupled, the inputs and outputs of the analog blocks, and the characteristics of the analog elements. The configuration registers can be dynamically programmed. Thus, the device can be used to realize a large number of different analog functions and applications.

Abstract: A dynamically and independently reconfigurable multi-mode device, and a method thereof. The device can include a controller for selecting a mode of operation. The device is configured according to the mode of operation. The configuration information corresponding to the mode of operation resides on the device such that the configuring is accomplished independent of a host device. The device also can include interface circuitry for simulating disconnection of the device from, and reconnection of the device to, the host device. The selected mode of operation is implemented between the simulated disconnection and reconnection.
