This paper addresses a low-cost and real-time solution for the implementation of super-resolution (SR) algorithms over SOC (System-On-Chip) platforms in order to achieve high-quality image improvements. Lowcost constraints are accomplished in the sense that SR is performed without developing a specific hardware, but re-using a video encoder IP block. This encoder can be used either in compressi...

This paper presents a high performance design for ContextBased Adaptive Variable Length Coding (CAVLC) used in the H.264/ AVC standard. A two-stage encoder is proposed to make the scan and encode stage work simultaneously. The scan engine scans four coefficients at each cycle. Parallel encoder for four “levels” and parallel encoder for four “Run before” are adopted to accelerate the encode engi...

In current Deep Submicron (DSM) era, interconnects play important role in overall performance of the chip. The factors such as power dissipation and crosstalk through RC modeled interconnects substantially affect the entire working of the chip. Therefore, to enhance the performance, minimization or elimination of coupling between interconnects is essential. Bus-invert method is the best method ...

In order to achieve adaptive channel coding and adaptive modulation, the main causes of degradation to system performance are the decoder selection error and modulator estimation error. The utilization of supplementary information, in an estimation system utilizing channel estimation results, blind modulation estimation, and blind encoder estimation using several decoders information and encode...

This work advocates the formulation of digital watermarking as a communication problem. We consider watermark-ing as communication with side information available for both encoder and decoder. A generalized watermarking channel is considered that includes geometrical attacks, fading and additive non-Gaussian noise. The optimal encod-ing/decoding scenario is discussed for the generalized waterma...

We describe a simple method for high-precision rotary angle encoder calibration for longrange angular errors. By using a redesigned electronic nulling autocollimator, an opticalpolygon artifact is calibrated simultaneously with determining the encoder error function over a rotation of 2π rad. The technique is applied to the NIST vacuum double crystal spectrometer, which depends on precise measu...

Hardware implementation of the JPEG 2000 image compression standard for real-time image compression requires implementation of the adaptive arithmetic encoder among other related algorithms. In this work, a system level design for the adaptive arithmetic encoder used in the JPEG 2000 standard is proposed. This design is based on the assumption that the bit-sequence and its corresponding context...

The β-encoder, introduced as an alternative to binary encoding in A/D conversion, creates a quantization scheme robust with respect to quantizer imperfections by the use of a β-expansion, where 1 < β < 2. In this paper we introduce a more general encoder called the βα-encoder, that can offer more flexibility in design and robustness without any significant drawback on the exponential rate of co...

Due to the magnetic nonlinearities, SRM drive control is complicated and normally requires a microprocessor or a DSP. This paper presents a simple and reliable SRM drive using an innovative encoder based on optical graphical programming technology. There is no microprocessor in the drive, no A/D or D/A circuitry, with a drive system that matches the simplicity of the motor construction. It feat...

A shape-adaptive search is defined based on the BISK scheme and it is applied to sign encoding and magnitude refinement of images. It can be generalized to a complete bitplane encoder whose performance is comparable to that of other state-of-the-art encoders. Key-Words: Lossy Data Compression, BISK, Non-Regular Boundary Images, DWT, Remote Sensing, High Resolution Images, Geographic Information...
