In this report, the DSP, and in general, digital and reconfigurable implementation of selected signal processing algorithms is described and analyzed in properly set up test beds. These laboratory prototypes allows to test the behavior of the signal processing algorithms when they are implemented on hardware platforms (DSPs and FPGAs), in the presence of data and metrics quantization, limited m...

This article presents PAPRICA-3, a VLSI-oriented architecture for real-time processing of images and its implementation on HACRE, a high-speed, cascadable, 32-processors VLSI slice. The architecture is based on an array of programmable processing elements with the instruction set tailored to image processing, mathematical morphology, and neural networks emulation. Dedicated hardware features al...

This paper describes a new paradigm of programming education using a large electronic whiteboard that combines the merits of classroom lectures using a black/white board and those of computer processing. Using this system, a teacher can write a program on the board, explain it, make the system recognize it and run the program in front of the class while keeping the attention of the students foc...

as milk is a liquid compound, it needs containers at every stages of movement. the first significant development in milk packaging created at the end of nineteenth century. the flavor changes and shelf life of pasteurized milk and ultra pasteurized milk are affected by processing conditions, packaging materials and microbial growth. off-flavor is an effective factor on reduction of milk quality...

Each CCD is a square 4 megapixel device, with 2048 pixels on each side. Photons impinging on the CCD first pass through an image intensifier. The aperture on the intensifier does not quite cover the entire CCD, instead covering only an “Active Region” that is 1388 x 1516 pixels in size. The CIPS instrument will be capable of telemetering to the spacecraft bus the data from the entire CCD or any...

PROJECT GOALS SRI and U.C.Berkeley are developing hardware for a real-time implementation of spoken language systems (SLS). Our goal is to develop fast speech recognition algorithms and supporting hardware capable of recognizing continuous speech from a bigram or trigram based 10,000 word vocabulary or a 1,000 to 5,000 word SLS system. RECENT RESULTS The special-purpose system achieves its high...

Different techniques have been developed for reading out microcalorimeter sensor arrays: individual outputs for small arrays, and time-division or frequency-division or codedivision multiplexing for large arrays. Typically, raw waveform data are first read out from the arrays using one of these techniques and then stored on computer hard drives for offline optimum filtering, leading not only to...

Owing to the rich processing, multi-modal sensing, and versatile networking capabilities, smartphones are increasingly used to build data-intensive embedded sensing applications. However, various challenges must be systematically addressed before smartphones can be used as a generic embedded sensing platform, including high power consumption, lack of real-time functionality and embedded program...

For over a half century, the United States space program has been a leading contributor to the health and growth of our nation from the perspectives of science, technology, economy, and defense. Given the nature and purpose of past, present, and future spacecraft, from earth science to space science and exploration to defense surveillance, one of the most critical needs and daunting challenges ...
