|20150256170||CIRCUITS WITH FLOATING BIAS - Apparatus and methods to increase the range of a signal processing circuit. A system uses floating bias circuits coupled to a signal processing circuit to increase the range of power supplies that can be used with the signal processing circuit, while maintaining the components of the signal processing circuit within a breakdown voltage threshold. As the voltage level of the data signal varies, the voltage level of the floating bias circuits varies as well.||09-10-2015|
|20150256169||APPARATUS AND METHODS FOR INPUT BIAS CURRENT REDUCTION - Apparatus and methods for reducing input bias current of electronic circuits are provided herein. In certain implementations, an electronic circuit includes a first input terminal, a second input terminal, an input circuit, and a plurality of input switches including at least a first input switch and a second input switch. The first input switch is electrically connected between the first input terminal and a first input of the input circuit, the second input switch is electrically connected between the second input terminal and a second input of the input circuit, and the first and second input switches can be opened and closed using a clock signal. The electronic circuit further includes a charge compensation circuit for compensating for charge injection through the first and second input switches during transitions of the clock signal.||09-10-2015|
|20150254078||PRE-FETCH UNIT FOR MICROPROCESSORS USING WIDE, SLOW MEMORY - In an example embodiment, a circuit is provided that includes a pre-fetch unit configured to pre-fetch instructions and data from a flash used by a microprocessor and decode the instructions and data without storing and accessing an address history, wherein the pre-fetcher is aware of the microprocessor's instruction set and performs parallel direct decode of each instruction accessed from the flash. In an example embodiment, method for pre-fetching instructions from a flash to a microprocessor is provided that includes reading a line of program code from the flash, assigning the instructions or data in the line to a thread in a hopper maintained in a cache, decoding the instructions to detect branches, and initiating a fetch from the flash if the target instruction is not found in one of the hoppers in the cache, building and maintaining predicted threads of instructions most likely to be executed by the microprocessor.||09-10-2015|
