PP architecture

The parallel processor (PP) is a 32-bit integer DSP optimized for imaging and graphics applications. Each PP

can execute in parallel; a multiply, ALU operation, and two memory accesses within a single instruction. This

internal parallelism allows a single PP to achieve over 500 million operations per second for certain algorithms.

The PP has a three-input ALU that supports all 256 three input Boolean combinations and many combinations

of arithmetic and Boolean functions. Data-merging and bit-to-byte, bit-to-word, and bit-to-halfword translations

are supported by hardware in the input data path to the ALU. Typical tasks performed by a PP include:

D Pixel-intensive processing

–

Motion estimation

–

Convolution

–

PixBLTs

–

Warp

–

Histogram

–

Mean square error

D Domain transforms

–

DCT

–

FFT

–

Hough

D Core graphics functions

–

Line

–

Circle

–

Shaded fills

–

Fonts

D Image Analysis

–

Segmentation

–

Feature extraction

D Bit-stream encoding/decoding

–

Data merging

–
