HIGH-THROUGHPUT MULTI STANDARD TRANSFORM

CORE SUPPORTING MPEG/H.264/VC-1 USING COMMON

SHARING DISTRIBUTED ARITHMETIC

ABSTRACT:

This paper proposes a low-cost high-throughput multi standard transform (MST) core,

which can support MPEG- 1/2/4 (8 × 8), H.264 (8 × 8, 4 × 4), and VC-1 (8 × 8, 8 × 4, 4×8, 4×4)

transforms. Common sharing distributed arithmetic (CSDA) combines factor sharing and

distributed arithmetic sharing techniques, efficiently reducing the number of adders for high

hardware-sharing capability. This achieves a reduction in adders in the proposed MST, compared

with the direct implementation method. With eight parallel computation paths, the proposed

MST core has an eightfold operation frequency throughput rate. The CSDA-MST core thus

achieves a high-throughput rate supporting multi standard transformations at low cost.

EXISTING SYSTEM:

Numerous researchers have worked on transform core designs, including discrete cosine

transform (DCT) and integer transform, using distributed arithmetic (DA), factor sharing (FS),

and matrix decomposition methods to reduce hardware cost. The inner product can be

implemented using ROMs and accumulators instead of multipliers to increase the area cost.

EXISTING SYSTEM TECHNIQUE:

Factor sharing (FS) and matrix Decomposition

EXISTING SYSTEM DRAWBACKS:

Low throughput

High cost

PROPOSED SYSTEM:

The proposed CSDA algorithm combines the FS and DA methods. By expanding the

coefficients matrix at the bit level, the FS method first shares the same factor in each coefficient;

the DA method is then applied to share the same combination of the input among each

coefficient position. The main strategy aims to reduce the nonzero elements using CSDA

algorithm.
