Low-complexity bit-parallel systolic architecture for computing AB/sup 2/+C in a class of finite field GF(2/sup m/)

“…; m [3]. It has been shown that an AOP is irreducible if and only if m + 1 is a prime and 2 is a generator of field GF (m + 1) [9]. For m 100, the possible m for an AOP of degree m to be irreducible are 2, 4, 10, 12, 18, 28, 36, 52, 58, 60, 66, 82, and 100.…”

“…. ; m01 g is called a canonical basis of GF (2 m ) [9]. Notably, the element A can also be represented as A = A0 + A1 + A2 2 + .…”

“…In MPEG-4 [3], wavelet transform is applied to encode the static texture. In wavelet-based video codec [9]- [11], motion estimation and motion compensation remove the temporal redundancy among adjacent frames; the spatial redundancy is reduced by wavelet transform. The block matching and discrete wavelet transform require intensive computation.…”

A novel current-mode multiplier/divider employing only single Dual-Output Current Controlled CDTA

“…Realizations of the current-mode multipliers and dividers can be separated into 2 main techniques, which are continuous-time signal and sampled-time signal based on switched-capacitor or switched-current technique [9][10]. The later method needs to inevitably employ clock signal to activate the circuit.…”
