Yashvanth Question

Dec 17, 2018 00:00

I'm currently using EVAL - ADAU1467 sigmaDSP which can be programmed through sigma studio ( I'm using Ver. 4.2 / 64 bit OS). As per my applications, I have to use complex number based calculations ( to account for spatial delays between signals in real time environment).

But, I'm not able to figure out, as to how this task can be done, as in I don't find relevant blocks in sigma studio, (to be put in the workspace), which can do the operations on complex numbers.

Kindly, someone, Help me out. Thanks in advance.

Hi Yashvanth,

You can find the blocks to do the complex number based calculations ((Splitter, Merger, Arithmetic operations, etc.,) in the Block schematic's Tools Box.

For a block domain schematic the SS framework buffers a block of samples for processing. This is typically used for FFT/IFFT processing which require buffers of complex data. As such, complex data is only supported in the block domain.
