Abstract—This paper presents a design of low cost and high throughput multistandard transform (MST) core using combination of Factor Sharing and Distributed Arithmetic called Common Sharing Distributed Arithmetic (CSDA) method. CSDA technique reduces the number of adders efficiently compared to the direct implementation by 44.5%.This architecture shares the available hardware resources, so the hardware cost gets reduced. With eight parallel computation paths, the proposed MST core has an eightfold operation frequency throughput rate. CSDA-MST core achieves a high-throughput rate, supporting the (4928 × 2048@24 Hz) digital cinema or ultrahigh resolution format. It supports MPEG-1/2/4 (8 × 8), H.264 (8 × 8, 4 × 4), and VC-1 (8 × 8, 8 × 4, 4 × 8, 4 × 4) transforms. Reduction of gate counts from 28,606 to 23,799 can be achieved here.
