Abstract: Systems and methods for performing a rake-finger operation on a vector processor are described herein. In one embodiment, a method for rake-finger processing comprises loading samples from a register into an execution unit, performing a rake-finger operation on the samples in the execution unit, and writing results from the rake-finger operation to the register. Performing the rake-finger operation comprises performing a finite impulse response (FIR) filter operation, and performing a despread operation, wherein filtered samples from the FIR filter operation are input to the despread operation without going through the register.

Abstract: Systems and methods for despreading a received signal are described herein. In one embodiment, a vector processor comprises a plurality of code generators, wherein each code generator is configured to generate a different code corresponding to a different code hypothesis. The vector processor also comprises a plurality of despread blocks coupled to a common input for receiving samples of a signal, wherein each despread block is configured to despread at least a portion of the samples with a different one of the codes to generate respective despreaded samples and to accumulate the respective despreaded samples over a length of the code.
