At present, many EEG cartographic systems are based on first generation signal processors such as the TMS 32010. These are primarily dedicated to the analysis of a limited number of channels, usually not in excess of 20. This paper presents a faster processing system allowing acquisition and analysis of a greater number of EEG signals. The system is of the master-slave type and structured around a DSP and a PC/AT computer. The slave utilizes the ADSP-2100 signal processor and performs two tasks, that is, acquisition and spectral analysis of all input channels. The master or PC/host serves as a terminal enabling the operator to display in a cartographic form the data obtained and, wherever necessary, to rescue and print the results. The system's hardware and software architectures and an application to test its performance are described.
