Biometric speech signal processing in a system with digital signal processor

Dual-ALU Processor for Speech Signal Processing

This paper proposed a low-cost dual-ALU processor for speech recognition. It does not give an emphasis on sophistication but on low-cost solution. The dual-ALU architecture provides parallel calculation capability. For the consideration of chip size, the area of the second ALU is only half of the first ALU. We use hardware-software codesign method to implement the speech recognition. The featur...

Radiometry Imaging System with Digital Signal Processing

The problem of high resolution radiometry imaging is considered. An iterative method of radiometry image processing is presented in the paper. The problem of image reconstruction is considered as the inverse ill-posed problem. The method proposed makes use of the iterative technique and regularization procedure to improve image quality. Nonlinearity of the method is provided by a nonnegative co...

Digital Signal Processor Trends

During the past decade digital signal processors (DSPs) have hit critical mass for high-volume applications (Figure 1). Today, the entire digital wireless industry operates with DSP-enabled handsets and base stations. The mass-storage industry depends on DSPs to produce hard-disk drives and digital versatile disc players. Ever-increasing numbers of digital subscriber line and cable modems, line...
