Block Diagram
The PMECC Error Location Controller provides hardware acceleration for determining roots of
polynomials over two finite fields: GF(2^13) and GF(2^14). It integrates 24 fully programmable
coefficients. These coefficients belong to GF(2^13) or GF(2^14). The coefficient programmed in
the PMERRLOC_SIGMAx register is the coefficient of degree x in the polynomial.
