RODRIGUEZ SUAREZ, Juan Raúl  and  DOMINGUEZ RODRIGUEZ, Ismel. Synchronous digital processor on real time supported in a fpga circuit spartan3e. Rev. cienc. tecnol. [online]. 2011, n.15, pp.43-52. ISSN 1851-7587.

This work intends the design, implementation and testing of a synchronous real time discrete processor supported on a reconfiguration circuit FPGA of the Xilinx Spartan-3E Starter Kit type. The design of a synchronous digital processor in real time is carried out and it is implemented on a circuit FPGA using the XSG tool that settles in the Simulink of MATLAB. An auxiliary card DSP_Gidam01 was also built that together with the card Xilinx Spartan-3E contains the components of the system. However, the control circuits and the digital processors are built on the FPGA reconfigurable circuit of the card. The use of the PROTEUS as tool is introduced for a short period, to build the PCB of the auxiliary card. The synthesis and operation of the processor is evaluated with the implementation of certain digital filters and the comparison among the simulated and real answers. An application is also presented for audio prosecution with a bank of filters.

Keywords : Processor; Reconfiguration circuit; Digital filters; Audio digitalization; FPGA.
