this paper describes the system design of a portable and economical mu rhythm based brain computer interface which employs cypress semiconductors programmable system on chip (psoc). by carrying out essential processing on the psoc, the use of an extra computer is eliminated, resulting in considerable cost savings. microsoft visual studio 2005 and psoc designer 5.01 are employed in developing th...

Most computer hardware today is nondeterministic, meaning that two executions of a program will not be cycle-for-cycle identical at the microarchitectural level even if they start from the same microarchitectural state. Due to uninitialized state elements, I/O, and timing variations on high-speed buses, the microarchitectural states of the two executions will evolve differently. Such nondetermi...

This paper describes three hardware devices for integrating modular synthesizers with computers, each with a different approach to the relationship between hardware and software. The devices discussed are the USB-Octomod, an 8-channel OSC-compatible computer-controlled control-voltage generator, the tabulaRasa, a hardware table-lookup oscillator synthesis module with corresponding waveform desi...

0272-1732/00/$10.00  2000 IEEE Traditionally, undergraduates in electrical and computer engineering study the design and implementation of a simple computer and then develop their own designs. In recent years, computer design courses have for the most part taken a simulation-only approach. Rapid prototyping techniques and a new generation of large field-programmable logic devices (FPLDs) enabl...

Computer data acquisition is more and more widely used in today’s undergraduate laboratory courses. To meet this trend, it is necessary to bring computer data acquisition to old laboratory equipment, such as a Tinius Olsen machine. One solution is to go to the equipment’s original manufacturer or other vendors for a retrofitting package with computer data acquisition, that usually costs thousan...

The increased complexity in today’s state-of-the-art computer systems make them hard to analyse, test, and debug. Moreover, the advances in hardware technology give system designers enormous possibilities to explore hardware as a means to implement performance demanding functionality. We see examples of this trend in novel microprocessors, and Systems-on-Chip, that comprise reconfigurable logic...

With the price of computer hardware decreasing steadily and the scope of data processing applications ever rising, the problem of upgrading a computer system is omnipresent. The myriad of potential pitfalls includes losing an investment in purchased hardware and software, reprogramming applications, reformatting data files, retraining personnel, operating two different systems in parallel durin...

Although available (sequential) computer hardware is very powerful nowadays, the implementation of artificial neural networks on massively parallel hardware is still undoubtedly of high interest, not only under an academic point of view. This paper presents an implementation of multi-dimensional Self-Organizing Maps on a scalable SIMD structure of a CNAPS computer with up to 512 parallel proces...
