can anybody suggest me a good algorithm for demodulating AM signals
that can be implemented in VHDL.

There are two incredibly complicated algorithms for lousy students:

1. Y = abs(X)
2. Y = sqrt(I^2 + Q^2)

Good is a relative term. The answer depends on the larger system context
of the demodulator.
