JPEG2000 image compression system consists of two main algorithms namely, discrete wavelet transform (DWT) and embedded block coding with optimized truncation (EBCOT). These algorithms are compute intensive and require efficient VLSI implementation for real time applications. Bit plane coder (BPC) and MQ coder are the two cores of the EBCOT algorithm. All processes to be executed by the MQ coder are...
This paper presents a design technique for multiple bit error correctable (fault tolerant) polynomial basis (PB) multipliers over GF(2m). These multipliers are the building blocks in certain types of cryptographic hardware, e.g. the Elliptic Curve Crypto systems (ECC). One of the drawbacks in the existing techniques is their inability to correct multiple bit errors at the outputs. Also, much attention...
This paper presents design of an 8-bit 1.8 V segmented current steering (CS) digital-to-analog converter (DAC) using 0.18 mum double poly five metal CMOS technology. The DAC has been segmented as 6+2 to achieve optimum performance for minimum area. The simulation result shows a maximum DNL of 0.30 LSB and an INL of 0.33 LSB. The midcode glitch is 0.27 pV s. The simulated SNDR and SFDR of the segmented...
This paper presents an 8 bit 1.8 V 500 MSPS digital- to analog converter using 0.18mum double poly five metal CMOS technology for frequency domain applications. The proposed DAC is composed of four unit cell matrix. A novel decoding logic is used to remove the inter block code transition (IBT) glitch. The proposed DAC shows less number of switching for a monotonic input and the product of number of...
We suggest a feature based facial image reconstruction technique. The encoding technique utilizes the affine structure of the face to capture the global facial motion. The structure information is transmitted only once at the bootstrapping stage. After that only the motion information for each frame is used to reconstruct the image at the decoder. An attempt is made to perform local reconstruction...
