Unavailability of frame based processing in HDL coder

Hi,

I am working on a Simulink model and I want to generate code for corresponding model using HDL coder.My model has blocks like Convolutional coder of rate 0.5 as well as puncturing to 3/4 code rate.This is input to rectangular qam modulator block.So frame based processing is inevitable as far as I have understood from studying this system.But the HDL coder do not support frame based processing.Please suggest me some methodology to solve this issue.

You will have to convert your model to a sample based version. Even in the sample based version, you can have access to more than the current sample by using RAMs or registers. For example, if you always want to have access to 4 samples, a tap delay will allow you to access these samples.

There are a few examples for HDL Code generation in Communications System Toolbox that illustrate how to go about implementing a Communications system.
