Addeddate Call number o CameraPages: This paper describes the design and implementation of a VHDL processor meant for performing 2D-Discrete Cosine Transform (DCT) to use in image compression applications.
Thus the FPGA implementation of image compression and are presented for the computation of the two-dimensional discrete cosine transform (2D DCT).

[John P Elliott] -- CD-ROM contains: Source code and test benches for the three case studies discussed in chapt 15, and DCT is the abbreviation for Discrete Cosine Transform; it can transform the signal from time domain to cosine domain.
It can represent a given signal in term of a sum of cosine functions oscillating at different frequencies. It is a powerful tool for signal analysis and can be applied to many important applications like data compression and so on.
Signature identification and verification is considered among the most popular biometric methods in the area of personal authentication. The proposed method is based on offline veAuthor: P.
Mhatre, M. Maniroja. In the past decade the main engine of electronic design automation has been the widespread application of ASICs (Application Specific Integrated Circuits). Present technology supports complete systems on a chip, most often used as so-called embedded systems in an increasing number of applications.
Embedded systems pose new design challenges which we believe will be the driving Cited by: Most video compression standards such as HDTV, H, JPEG and MPEG use Discrete Cosine Transform (DCT) as a standard transform-coding te Cosine Transform is decomposing the signal into weighted sums of cosine harmonics; unlike DCT, Discrete Fourier Transform decomposes the signal into weighted sums.
Behavioral Synthesis: A Practical Guide to High-Level Design includes details on new material and new interpretations of old material with an emphasis on practical information.
The intended audience is the ASIC (or high-end FPGA) designer who will be using behavioral synthesis, the manager who will be working with those designers, or the.
The compression DCT IP was developed under vivado HLS, while the chaos generators were described in VHDL. (4) The reconfigurable decompression and decryption IP is the proposed IP including Inverse Discrete Cosine Transform (IDCT) and chaos according to the algorithms in Section 2.
The decompression DCT IP was developed under vivado HLS, while Cited by: Publisher Summary. Reconfigurable computing systems are built on a variety of existing technologies and techniques.
It is always difficult to pinpoint the exact moment a new area of technology comes into existence or even to pinpoint which is the first system in a new class of machines.
Fourier-based filtering techniques, such as the ideal low-pass and Butterworth filters are then introduced. The Fast Fourier Transform is also discussed.
Finally, the Discrete Cosine Transform, used later in JPEG and MPEG, is next unit discusses.

Oppenheim and Schafer, Discrete Time Signal Processing, Prentice Hall. Discrete Cosine Transform (DCT) configures the most important part of the JPEG lossy compression.
The basic operation of DCT is to transform information in one form of representation to another form. In the DCT transformation, the insignificant portions of image that have unnoticeable impact in image structure will be identified and can be Cited by: 1.
