For cost reasons, the usage of conventional dynamic RAM (SDRAM) is preferred. However, accessing SDRAM is a complex task, especially if multi-stream access, different stream types and realtime capability are an issue. The paper describes a multi-stream SDRAM controller IP (intellectual property) that covers different stream types and applies memory scheduling to achieve high bandwidth utilization. Two different architectures are presented and discussed; simulation results with a realistic application configuration demonstrate up to 90% of maximum memory bandwidth utilization. The scheduler IP is suitable for FPGA implementation and is flexible enough to be used in other applications.","PeriodicalId":173186,"journal":{"name":"2003 IEEE Workshop on Signal Processing Systems (IEEE Cat.

Since the proposed technique uses a discrete cosine transform (DCT) over each frequency band data, obtained directly from the DCT domain by multiplying precalculated matrices, compatibility can be preserved easily with DCT-based image/video standards. First, we present the 1D case, followed by an extension to the 2D case. The proposed coder is observed to result in significant reduction of memory and computational complexity requirement with higher peak-signal-to-noise ratio (PSNR), when compared with traditional hierarchical image coding methods.","PeriodicalId":173186,"journal":{"name":"2003 IEEE Workshop on Signal Processing Systems (IEEE Cat.

With the increasing demand for portable, power-aware, multimedia devices, an architecture that can be flexible in both power consumption and compression quality is required. To meet the requirement, the paper presents a novel power-aware architecture, called the vario-power architecture, for motion estimation. Based on a semi-systolic array with a content-based subsample algorithm, the architecture dynamically disables some processing elements to reduce the power consumption. By performing edge extraction first, a threshold is then set as the criterion of whether to enable/disable processing elements and thus the switching activities of the system can be reduced. As a result, the architecture may operate dynamically at different power consumption modes, according to the remaining capacity of the battery pack, with little quality degradation.","PeriodicalId":173186,"journal":{"name":"2003 IEEE Workshop on Signal Processing Systems (IEEE Cat.

Most published IMDCT computing algorithms focus mainly on either the reduction of computing complexity but overlook the hardware realization issues, e.g. memory access complexity and efficient mapping of the computing kernel. By exploiting the symmetric properties in computation, we first convert an N-point IMDCT to an N/2-point DCT-II problem. A fast DCT-II computing scheme is next derived and the overall scheme is further optimized to remove redundancy. Based on the proposed fast IMDCT computing scheme, a novel design mapping is developed to minimize memory access complexity without stalling the pipelined computation. The mapping features simple address generation, small temporary storage size and low access bandwidth. Performance analyses show that, given the same hardware resource allocation, the proposed design can outperform other well known IMDCT designs in terms of memory storage size, computing latency or fixed point implementation error.","PeriodicalId":173186,"journal":{"name":"2003 IEEE Workshop on Signal Processing Systems (IEEE Cat.

Several watermarking algorithms have been proposed for image, video, audio and text in the current literature. Digital watermarking is the process that embeds data, called a watermark, into a multimedia object such that the watermark can be detected or extracted later to make an assertion about the object. The number of software implementations of the proposed algorithms is significantly large, whereas a hardware implementations is lacking. Hardware implementation has advantages over software implementation in terms of low power, high performance, and reliability. We have developed a hardware system that can insert both robust and fragile invisible watermarks in the image. The hardware module can be easily incorporated in a JPEG encoder to develop a secure JPEG encoder. The watermark module is implemented using 0.35 /spl mu/m CMOS technology. To our knowledge, this is the first watermarking chip implementing both invisible-robust and invisible-fragile watermarks.","PeriodicalId":173186,"journal":{"name":"2003 IEEE Workshop on Signal Processing Systems (IEEE Cat.

World Wireless Congress, 2003). We present the mapping of the Viterbi decoding algorithm on this architecture. Initially, algorithm analysis and vectorizing transformations are discussed. The resulting vectorized algorithm is used for defining two generic vector instructions for Viterbi decoding. These are the 'add-compare-select' (ACS) and Manhattan distance (MANH) instructions. The design of these instructions is presented and their genericity is demonstrated by discussing how various Viterbi decoder instances (such as M'ary Viterbi and Viterbi decoding for blind. transport format detection) can be implemented using CVP (co-vector processor) Viterbi instructions. Finally, the throughput estimations of two binary Viterbi decoder implementations (UMTS and GSM) are benchmarked against a number of existing processors. The results present a higher throughput than comparable architectures, demonstrating that a good tradeoff has been achieved between instruction set flexibility and decoding throughput.","PeriodicalId":173186,"journal":{"name":"2003 IEEE Workshop on Signal Processing Systems (IEEE Cat.

The method includes a render unit that animates a face based on a set of FAPs. The render unit provides feedback to the FAP generation process as guidance toward an optimal set of FAPs. Our optimization process consists of minimizing a penalty function, which includes a matching function and a few barrier functions. The matching function compares how well an animated face matches with the original face. Each barrier function indicates the level of distortion from a normal looking face for a certain part of a face, and advises the optimizer. Unnecessary FAPs are eliminated and the search is partitioned to speed up the optimization process. Three different search techniques, steepest descent method, linear search method, and cyclic coordinates method are applied to derive an optimum.","PeriodicalId":173186,"journal":{"name":"2003 IEEE Workshop on Signal Processing Systems (IEEE Cat.

The paper presents the quantized color pack extension (QCPX) ISA to improve execution performance of multimedia processing applications on programmable superscalar processors while reducing the energy consumption for these applications. QCPX exploits parallelism within the color space representation (YCbCr - luminance-chrominance) in addition to generic subword parallelism exploited by existing multimedia instruction set extensions (e.g., MMX, SSE, MDMX). We evaluate the performance (execution time in cycles) and energy consumption using QCPX on a media benchmark suite that includes vector median filter, scalar median filter, edge detection, and vector quantization. Our experimental results indicate that a 32-bit QCPX version achieves speedups ranging from 205% to 562% compared with that of a 32-bit baseline RISC version and 90% to 100% over the 32-bit MDMX-like version on identically configured, dynamically scheduled ILP superscalar processors. In addition, the QCPX version reduces the energy consumption from 69% to 83% over the baseline version and 47% to 50% over the MDMX-like version due to the significant reduction of executed instructions and cache accesses.","PeriodicalId":173186,"journal":{"name":"2003 IEEE Workshop on Signal Processing Systems (IEEE Cat.
