Abstract :
This paper describes a technique for reconstructing tomographic images generated by a minitomograph scanner for soil science developed by Embrapa Agricultural Instrumentation using a parallel DSP architecture with an HEPC2E board from Hunt Engineering with two TMS32OC40 processors from Texas Instruments. The software designed for visualization of bi- and tri-dimensional images uses code composer tool combined with Parallel C from 3L and Borland Builder C++. Reconstruction and interpolation tasks were distributed throughout the platform processors, using parallel algorithms in order to improve speed and processing power. The work resulted in an increase of about 15% in the system speed when compared with that reached using a classical platform at 200 MHz
