MATLAB: 16 bit input output parameter generation using HDLCoder

Question

Hello all,

I'm using HDL Coder tool to generate Verilog modules for FPGA implementation. My design is a Adaptive Predictor for Speech Signal. I see that HDL Coder always generates a 14-bit input & output parameters. Is there a way by which I can generate 16-bit signals?

Thank you,

HDL Coder allows you to choose the default word length to suggest during fixed-point conversion. This is settable on the "Fixed-Point Conversion" tab in the Workflow Advisor, when you have selected "Propose fraction lengths". You can also choose a fixed fraction and let the tool choose the word length.
