Interfacing a TMS320C31 DSP to the PC Bus

چکیده
This paper describes an 8-bit data interface circuit between the ISA bus and the digital signal microprocessor TMSC320C31 from Texas Instruments. It has firstly been part of an H.261 video encoder board and then used in other PC boards such as an ISDN, an H.261 video decoder and a QCIF video codec. The C31-ISA interface’s simplicity and functionality are the key for such usage in the Telecommunications Institute-Pole of Coimbra. The low cost interface only consists of four ICs, a 2K*8 dual-port static RAM, two 20-pin PAL and a 20-pin data transceiver circuits.

متن کاملImplementing an Adaptive Noise Cancelling System to Enhance Sonar Receiver Performance Using the TMS320C31 DSP
The performance of sonar receivers on board a ship are degraded by mechanical noise. In order to improve the detection performance of the acoustic sensors (hydrophones), we have designed a local mechanical noise cancelling system using the Adaptive Noise Cancelling (ANC) approach with a single noise reference [1]. The implementation was realized and validated on underwater acoustic signals with...

متن کاملImplementation and Critical Investigation on Modulation Schemes of Three Phase Impedance Source Inverter
New control circuits and algorithms are frequently proposed to control the impedance (Z) source inverter in efficient way with added benefits. As a result, several modified control techniques have been proposed in recent years. Although these techniques are clearly superior to the simple boost control method which was initially proposed along with the Z-source inverter (ZSI), little or conf...
متن کاملTeaching DSP concepts using MATLAB and the TMS320C31 DSK
A graphically-oriented MATLAB program written by the authors facilitates teaching real-world digital signal processing concepts such as quantization of digital filter coefficients that occur in fixed-point processors, for example the widely used TMS320C5x. While many universities have or plan to buy the inexpensive floating-point TMS320C31 DSKs for pedagogical reasons, this MATLAB program simul...
