As a SIMD processor, ReSP gets data level parallel by using CB parallel, EU parallel and sub-word parallel, all of which are supported by hardware parallel.
The three-hierarchical data parallel provides high level DLP.
Hardware parallel of the second mode is lower than the first mode.
This is because that computing of Rake receiver is constrained by time which disperses operations of hardware.
In the first mode, parallel data paths and data locality of FFT are explored, which promote hardware parallel effectively.
