Hi all
I'm absolutely new to FPGAs, in fact my work is much more related with the SW than with the HW, so I need to solve a problem that ideally I was not targeted to.
The issue is this: I have to estimate (roughly) the number of FPGAs needed to support a typical signal processing algorithm, steps are as follows, always in single-precision:
1.16k complex samples FFT- 16k complex vector multiplication
- 16k complex samples IFFT
- 16k complex vector multiplication
- 16 k complex vector sum
The idea is to know how many FPGAs will cover this kind of processing in a given time, to compare with different types of processors. Por the later, it is really easy just counting number of operations in GFLOPs, but with hardware devices I am getting a lot of trouble, since I don't have a clear understanding on what should I count.
Please, give me a hand!
