Patent ID: 7530004

Claim:
A threshold logic unit (TLU) for performing detection on a serial stream of multi-valued data, the TLU having: a decision function having: a plurality p of registers for storing a succession of input values, each said register having an output and an input coupled to an adjacent said register; a plurality p of multipliers, each said multiplier forming the product between a unique said register input or output and a weight value W; a summer having an output equal to the sum of said multiplier products; a threshold for converting the output of said summer to a single-valued output by comparing the output of said summer to a decision history value; a decision history function having: a shift register having a plurality m of registers, each said register output coupled to an adjacent said register input; a look-up table coupled to each of said m registers, said look-up table converting the address formed by said shift registers into an output value; said decision history function look-up table output value generating said decision history value.
