Abstract

Multi-media equipment development must provide functions adjusted to human sensibilities. Realization of such functions depends on how the three transfer levels - perception, recognition, susceptibility-are handled. In this paper, we deal with perception by employing inverse problem to characterize the system and correctly reproduce signals. To accommodate recognition and susceptibility, we propose an optimization method in which results are compared repeatedly with a model of human recognition characteristics. With respect to system response, numerical models, filter design, playback, evaluation, estimates of cost and performance when implemented as semiconductor circuits, and generation of a netlist for semiconductor production, we propose an environment for hardware/software co-design and development based on four steps which make possible comprehensive, systematic development and design, from the conceptual stage through to production. A procedure for solving the inverse problem is incorporated in the four areas of this environment, which are interconnected and efficiently linked to the development process, so that the overall development cycle can be shortened. This proposal was applied to the development of a television receiver and audio circuitry, and its effectiveness confirmed.
