In this paper a general model for array-based approximate arithmetic computing (AAAC) is proposed to guide the minimization of processing error. In this model the key building block of AAAC circuits is the Error Compensation Unit (ECU). While designing the ECU, the two most critical problems are identified viz., determination of optimal error compensation values and identification of optimal er...

This paper presents a discrete-time robust control for electrically driven robot manipulators in the task space. A novel discrete-time model-free control law is proposed by employing an adaptive fuzzy estimator for the compensation of the uncertainty including model uncertainty, external disturbances and discretization error. Parameters of the fuzzy estimator are adapted to minimize the estimat...

This study aims at finding an efficient compensation method of transmission errors in low bitrate mobile communications using the H.263 video codec. For this aim, we suggest a novel error compensation method in the encoder (or transmitter), that can remove visual quality degradation due to spatio-temporal error propagation by utilizing a feedback channel. Most of all, our proposed method can re...

In many high speed Digital Signal Processing (DSP) and multimedia applications, the multiplier plays a very important role because it dominates the chip power consumption and operation speed. In DSP applications, in order to avoid infinite growth of multiplication bit width, it is necessary to reduce the number of multiplication products. Cutting off n-bit Less Significant Bit (LSB) output can ...

Overlapped block motion compensation or B-frames are examples of multihypothesis motion compensation where several motion-compensated signals are superimposed to reduce the bit-rate of a video codec. This paper extends the wide-sense stationary theory of motion-compensated prediction (MCP) for hybrid video codecs to multihypothesis motion compensation. The power spectrum of the prediction error...
