A method for developing a circuit is disclosed. The method generally comprises the steps of (A) generating a solution space having a dimension for each of a plurality of parameters for the circuit, (B) evaluating a plurality of instances of the circuit in the solution space through a software simulation, (C) evaluating the instances through a hardware simulation, and (D) updating the instances in response to the software simulation and the hardware simulation to approach an optimum instance of the instances for the circuit.

Decoder using a memory for storing state metrics implementing a decoder trellis

A method for decoding an encoded signal. A first step generates a plurality of first precision state metrics for a decoder trellis in response to a plurality of first precision branch metrics. A second step generates a plurality of second precision state metrics for a selected subset of the first precision state metrics in response to a plurality of second precision branch metrics. A third step replaces the selected subset of first precision state metrics with the second precision state metrics. A fourth step stores the first precision state metrics and the second precision state metrics.

Multi-resolution Viterbi decoding technique

A method for optimizing an algorithm specified for implementation on an integrated circuit for a specified application. The algorithm is analyzed with respect to its performance, and estimates of implementation area and speed are calculated. Specifically, the degrees of freedom for the algorithm alternations under specific targeted implementation objective functions and constraints are identified. The algorithm solution space is then searched to identify the algorithm structure that is best suited for the specified design goals and constraints. Algorithm parameters which satisfy performance metrics and can be implemented with minimum silicon area are identified.
