Matlab (.m) to VHDL


I have seen this question many times in the newsgroups but I did not see a clear answer. I have to perform various operations on arrays of data (such as multiplication, addition, finding mean, etc.). I have code written in Matlab and would like to translate it to vhdl. I understand that such subroutines as imagesc, imwrite, etc. might not be possible to translate to vhdl and will need to be written (or similar functions might be already implemented in vhdl). Is there anyway of directly translating Matlab code directly to vhdl? Can this be done using Simulink (Xilinx System Generator)? I don't have System Generator at home and Xilinx doesn't seem to have evaluation version (asking for Product Serial Number). Or maybe my question should be: can this be done in Simulink to start with? I have Xilinx FPGA/ISE. And if this can not be done using System Generator, is there anything else that can be used?

Please let me know if my requirements are not very clear.

Thanks, Vitaliy

At the moment there is no such thing. There are several Simulink based tools out there which help you get to hardware. You have to pay for these though, and you will really have no "golden" code if you go this route.

I have written VHDL packages:

Which follows the rules in Matlab, so creating this program should be possible.

Please look at the AccelDSP tool from Xilinx.. It is based on Matlab language to HDL conversion for Xilinx devices.

System Generator is based on Simulink based design environment to HDL conversion for Xilinx devices.

Vitaliy, There was a paper presented at MAPLD bridging Matlab using the library David talked about. The abstract of the paper is posted at:

I expected to see the paper there too, but did not see it. You can contact the conference organizer and see if or when it will be available.
