Title: Efficient interrupt return address save mechanism
Inventor: SMITH RODNEY WAYNE
IPC: G06F9/38
Filed: 2007-07-24
Abstract: A system, apparatus and method for efficiently processing interrupts using general purpose registers in a pipelined processor. In accordance with the present disclosure, a register file may be updated to efficiently save an interrupt return address. When an interrupt request is received by the system's processor, or when the request is issued in the execution of a program, a pseudo-instruction is generated. This pseudo-instruction travels down the pipeline in the same way as other instructions and updates the register file by causing the register file to be written with the return address of the last instruction for which processing has not been completed.

Patent CA-2659665-A1 (CA)
Inventor: MICHAELS ALAN J
IPC: H04B1/707
Filed: 2009-03-23
Abstract: A method is provided for improving a signal-to-noise ratio in a received signal. The method involves receiving a spread spectrum signal (SSS ) with a power level below a noise floor of a receiver. The SSS is generated by modulating a data signal using a spreading sequence (SS) comprised of a random number sequence (RNS). The SS can be generated using a chaos generator or any other deterministic means. The method also involves comparing a magnitude of each number of the RNS which was used to generate the SSS to an adaptable threshold value. The adaptable threshold value is selected based on a minimum magnitude of each number necessary to produce samples having a predetermined signal-to-noise ratio. Notably, samples of the received SSS are excluded from a receiver processing based on a result o f the comparison. Similarly, each number of a random number sequence is excluded from the receiver processing based on the comparison.

Abstract: Systems and methods are presented for transmitting additional data over preexisting differential COFDM signals by changing the amplitude of the legacy data symbols Additional bandwidth can be achieved for a COFDM signal while maintaining backward compatibility Additional information is overlaid on a legacy COFDM  signal by applying an amplitude offset to the legacy symbols Special receiver processing can be implemented to extract this additional information, which can include performing channel equalization across frequency bins to isolate the amplitude modulated overlay signal For example, at each FFT symbol time average power across neighboring active data bins can be used to determine the localized power at the corresponding FFT bins, and a channel inversion can then, be performed on the data bins to restore, as best as possible, the original transmitted symbol amplitude
