VHDL Mathematic function Implementation

[AdvaRes]

Hi members,
Can someone tell me how to implement this function in VHDL:
A*B

Where:
A is a signed 16 bit data
B=∑dij.(2^i)
Thanks in advance

Hi
Is dij a float value.convert to bit vector.
A is signed 16 bit data so MSB represents sign value one for negative zero for positive.
check for conditions based on this.
2^i is simple shift opeartion- left shift by i times.
I hope this helps and further discussion welcome...

regards,
Vinod

Thanks,
For your help. I forgot to say that dij can be 0, 1 or -1. These values are taken from a matrix. How to compute B ?

size of your matrix i.e., i,j range...and model it has a RAM..
