This technical report describes AGNI (meaning Fire in Sanskrit) – a VLSI chip to implement
error control codes. The chip was initially conceived and designed as part of a Georgia Tech
Cutting Edge Research Grant. However, this chip implementation of error control codes has
been undertaken as a part of the ECE 6130 course taught in Spring 2002 by Dr. John
Uyemura, Professor, Department of Electrical and Computer Engineering, Georgia Institute
of Technology. Two coders have been implemented: a (12, 6, 4) wavelet encoder/decoder
and a (24, 12, 8) golay encoder/decoder, where the (N, M, d) nomenclature stands for
(N=encoded length, M=message length, d=hamming distance). These codes have a
correctable limit of one bit error and three bit errors, respectively. The following section
presents the encoding/decoding functionality of the chip in more detail.
This project could potentially feed a future project to incorporate the chip into a System-ona-
Package (SoP). It is expected that the chip would function as a high-speed error
encoder/decoder for Radio Frequency (RF) applications.
