The Creonic AWGN Channel IP core is a noise generator capable of processing up to a maximum of 512 symbols in parallel. The IP core was developed with the aim of allowing the performance evaluation of a digital communication system in the presence of Additive White Gaussian Noise. The emphasis is on evaluating systems with low bit error rates. Unlike a software-based AWGN generator, which might take several hours and even days for the stated purpose, a hardware-based AWGN generator requires significantly less time. Run-time is reduced by several orders of magnitude.
