Logarithmic arithmetic for real data types and support for Matlab/Simulink based rapid-FPGA-prototyping

The paper is focused on the rapid prototyping for FPGA using the high-level environment of MATLAB/Simulink. An approach using the Xilinx system generator (XSG) is reviewed on an example of the high-speed logarithmic arithmetic (HSLA) unit. An alternative approach using the combination of the real time workshop (RTW) with the Handle-C compiler for automatized generation of the HDL code is presented. Finally, the possibilities to extend this solution in order to support the run-time reconfigurations are outlined.
