A 1080 p high profile H.264 encoder is designed by the robust reusable silicon IP methodology and fabricated in a 0.13 mum CMOS technology with an area of 10 mm<sup>2</sup> and 242 mW at 145 MHz. Compared to the state-of-the-art design targeted at 720 p baseline, this design reduces 53.4% power and 46.7% area through parallelism enhanced throughput and(More)
Previously we have demonstrated that a Rhodiola crenulata extract (RCE), containing a potent antioxidant salidroside, promotes neurogenesis in the hippocampus of depressive rats. The current study was designed to further investigate the protective effect of the RCE on neurogenesis in a rat model of Alzheimer's disease (AD) induced by an(More)
This paper presents a fast block type decision algorithm for 4/spl times/4, 8/spl times/8 and 16/spl times/16 intra prediction in H.264/AVC FRExt (fidelity range extension). With additional 8/spl times/8 intra prediction size, the complexity of intra prediction is increased by almost 50%. Thus, the proposed algorithm uses the smoothness of the macroblock to(More)
—Motion estimation (ME) in high-definition H.264 video coding presents a significant design challenge for memory bandwidth, latency, and cost because of its large search range and various modes. To conquer this problem, this paper presents a low-latency and hardware-efficient ME design with three design techniques. The first technique on integer-pel ME(More)
The aim of this study was to investigate if preadministration with Ganoderma lucidum spore (GLS) could (1) alleviate oxidative stress and mitochondrial dysfunction in rat hippocampus of intracerebroventricular (ICV) injection of streptozotocin (STZ), (2) protect neurons from apoptosis, and (3) improve cognitive dysfunction. Three groups of Sprague-Dawley(More)
—This paper presents a HD1080p 30-frames/s H.264 intra encoder operated at 140 MHz with just 94 K gate count and 0.72-mm 2 core area for digital video recorder or digital still camera applications. To achieve high throughput and low area cost for high-definition video, we apply the modified three-step fast intra prediction technique to reduce the cycle(More)
The paper presents a hardware-efficient fast algorithm and its architecture for large search range motion estimation (ME) used in HDTV sized H.264 video coding. To solve the high cost and latency in large search range cases, the proposed algorithm processes ME in parallel multi-resolution levels instead of serial processing in the previous approach. This(More)
This paper presents a set of fast algorithm and VLSI architecture for HDTV-sized H.264 fractional motion estimation. To solve the long computational latency in HD-sized application, we propose to use the single iteration algorithm with only six search points. This single iteration method halves the cycle count of two iteration methods in previous(More)
We have developed a new pel subsampling-based search hardware for motion estimation called quartet-pel motion estimation (QME). The memory access of search range memory can be reduced to 25%. The computational complexity can also be reduced to 25% with respect to full-search block matching algorithm (FBMA). On the other hand, flexible and efficient hardware(More)
