Wi-Fi audio hub for headphones and speakers. It lets instantly share 
wireless audio with multiple simultaneous listeners using any earbuds, 
headphones or powered speakers. I need a help design this project using 
VHDL. This is going to be system on chip design. I need some help in 
designing

Get the WiFi Data from the receiver of the SoC.
Forward the data through the MAC of the SoC to the Processor of the SoC. 
Pass it through the software stack running on the processor core.
Decode data and generate audio stream.
Feed the stream to the DACs on the soC. Amplify the audio signals... 
Voila..

If you don't find a suitable SoC on the market you can easily create 
your own ASIC.
Parts of it can be described in VHDL.

A really nice project for a rainy weekend.

Hi Schlumpf

Thank you very much for your help. I wanted build my own ASIC. What sort 
of modules can I build using VHDL on the SoC.

Can you give me some idea about this.

Thank you very much

Ah, don't be afraid. I will write all the source code for you, HDL as 
well as the software. I will do the formal verification and I will also 
do the chip design. What technology do have in mind? 22nm, or even 12nm? 
No problem. This afternoon I am a bit busy, but perhaps I can do it 
later in the evening. Usually these things employ a team of experienced 
embedded designers for a couple of months or a year, but for you I will 
do this in an hour, Captain.
Just give me your email address, I will send you the final chip mask 
layout tomorrow before 10.

Btw, if you feel there is some sarcasm in this posting, you may be 
right, and you should think about the reason for that. A good starting 
point may be "I wanted build my own ASIC."

Sure..
The processor core
The MAC controller
The decoder
Parts of the DAC
Some glue logic and wrapper

But first of all you have to go to your mummy and ask her to give you a 
couple of million dollars..

Thank you for your valuable suggestions. What if  I built the processor 
with VHDL. Then the processor interface with modules like the ESP32 for 
wifi and bluetooth.

Then why the FPGA?
The ESP is able to handle the whole job...

What if you start your first VHDL design with a blinking LED?

Seems that you have no clue of VHDL/FPGA/ASIC..
