    摘要： A method for switching between instruction contexts within a time interval in a multi-mode wireless broadband processing system. The method can include executing critical task operations that complete execution within a time interval, a critical task including a plurality of critical task operations, executing non-critical task operations that are able to cross a time interval boundary, a non-critical task including a plurality of non-critical task operations, and entering a sleep mode in which no critical task operations or non-critical task operations are executed, if the critical task operations and the non-critical task operations begun in the time interval have been completed before a following time interval begins.

    摘要： A system and method Fast Fourier Transform (FFT) method in a multi-mode wireless processing system. The method can include loading an input vector into an input buffer, initializing a second counter and a variable N, where N=log2 (input vector size), and s is the value of the second counter, performing an FFT stage, and comparing s to N and performing additional FFT stages until s=N. Performing the FFT stage can include performing vector operations on data in the input buffer and sending results to an output buffer, the data in the input buffer comprising a plurality of segments, advancing the value of the second counter; and switching roles of the input and output buffers. The vector operations can include performing Radix-4 FFT vector operations on the four input data at a time and multiplying the resulting output vectors with a Twiddle factor.

    摘要： A system and method for performing a convolution operation in a multi-mode wireless processing system. The method can include loading an initial value and a stride value into an address generator, generating an address based on the initial value and the stride value, supplying the generated address to a series of memories, loading input data into a series of registers, multiplying the contents of each register with a value stored at the generated address in the memory associated with each register, adding up the resulting multiplication products, and generating output based on the resulting sum. The number of memories and registers are equal, each register having an associated memory.

    摘要： A method for conserving resources in a communication system includes entering an awake state from a sleep state at a first time, where the first time occurs a predetermined period prior to a communication event. The predetermined period is greater than or equal to a worst-case determination period for determining a timing offset relative to an access point. An initial timing offset relative to the access point is determined during the predetermined period. The sleep state is entered for a remainder of the predetermined period upon determination of the initial timing offset. The awake state is entered for the communication event. The timing offset relative to the access point is determined based at least in part on the initial timing offset.
