The objective of this paper is present the voice evaluation codification using a real-time voice training system, with tactile and visual feedback based on a game, to be used by deaf people for learning of fundamental frequency. The system consist in a microcontrolled signal generator and a Matlabreg language routine. The signal generator is programmed using serial communication to activate a vibrotactile...
The man-machine interaction through speech allows, in many applications, an attractive, comfortable and effective communication. However, processing requirements still make it difficult the implementation of man-machine vocal communication systems in devices with low computational power, such as mobile phone, palmtops and home equipments. This paper describes the development of a signal preprocessing...
This work describes the development of an optimized partitioning algorithm for HW/SW codesign, which employs more realistic cost measures than previous partitioning algorithms and takes into account FPGA reconfiguration time. This algorithm is then used to find the optimal implementation of a digital RAKE receiver for DS-CDMA on an heterogeneous (hardware/software) platform. We additionally describe...
An optimized partitioning algorithm for HW/SW codesign is described and applied to the implementation of a digital RAKE receiver for DS-CDMA on an heterogeneous (hardware/software) platform. The development of this partitioning algorithm aims to gather quality features that have already proved effective when applied separately, but had not been used together yet. The partitioning algorithm is applied...
