With the development of Internet and cloud computing, multimedia data, such as images and videos, has become one of the most common data types being processed. As the scale of multimedia data being still increasing, it is vitally important to efficiently extract useful information from such a huge amount of multimedia data. However, due to the complexity of the core algorithms, multimedia retrieval applications are not only data intensive but also computationally intensive. Therefore, it has been a major challenge to accelerate the processing speed of such applications to satisfy the real-time requirement. As Graphic Processing Unit (GPU) has entered the general-propose computing domain (GPGPU), it has become one of the most popular accelerators for the applications with real-time requirements. In this paper, we parallelize a widely-used image retrieval algorithm called SURF on GPGPU, which is the core algorithm for many video and image retrieval applications. We first analyze the parallelism within SURF to guarantee that there are sufficient tasks being mapped to the large-scale computation resources in GPGPU. We then exploit some inherent GPGPU characteristics, such as 2D memory, to further boost the performance. Finally, we provide some optimization to the cooperation between CPU and GPGPU, which is generally ignored in previous designs. Experimental results show that our parallelization and optimization achieve a throughput of 340.5 frames/s on a NVIDIA GTX295 GPGPU, which is 15X faster than the maximal optimized CPU version. Compared to CUDA SURF, a state-of-the-art parallelization of SURF on GPGPU, our system achieves a speedup by a factor of 2.3X. © 2012 ACM.

A novel method for SRAM cell standby leakage measurement is presented, which enables accurate testing and decoupling of sub-threshold leakage (I-sub), gate leakage (I-gate) and junction leakage (I-junc) in each SRAM cell transistor. Moreover, the array based technique can not only precisely measure small current but also compensate the impact from random variations. The front-end SRAM array layout is kept original to preserve actual physical environment. The method is verified in SMIC 65nm technology. The data of I-sub, I-gate and I-junc of pull-down (PD), pull-up (PU) and pass-gate (PG) transistor are collected for process optimization to reduce standby power. © 2012 IEEE.

This paper presents a high performance VLSI design of Context-Based Adaptive Variable Length-Coding (CAVLC) for 4096×2160p@60fps H.264/AVC encoder. A parallel architecture is proposed to make the scan and encode stage work simultaneously. Four coefficients are scanned in parallel, and four Levels and Run_before are coded in parallel. From experimental results, only 120 cycles at most are needed to process one macroblock (MB), which reduce more than 50% cycles compare to state-of-the-art designs. The hardware implementation results show that the proposed design achieves real-time encoding at 250 MHz and the hardware cost is about 32k gates.

Fast Fourier transformation (FFT) is a key operation in digital communication systems. Different communication standards require various FFT length and precision. In this paper, we present a low power Application-Specific Instruction-set Processor (ASIP) for variable length (16-point-4096-point) and bit precision (8-bit - 16-bit) to meet different requirements. We use scalable multipliers to construct the butterfly unit, which support both 8-bit and16-bit operation. The order of butterfly operation is adjusted to reduce twiddle-factorROM accesses, so as to reduce overall power consumption efficiently. Clock Gating is implemented to shut down processor's pipeline during the FFT processin terms of special low power demands. Special Instructions are tailored to make full use of the flexible hardware.
