Generating a data path macro cell based upon a text format template comprising variables. The system provides for creating a text format template by generating a text format representation of a data path macro cell based upon data representing a graphical layout of the data path macro cell. Variables are substituted for constants. Variables are changed to values associated with a macro cell having desired characteristics to create a text format file representative of a desired macro cell. Graphical data representing the layout of a macro cell is generated based upon the text format file.

System for automated generation of data path macro cells

A hearing compensation system for the hearing impaired comprises a plurality of bandpass filters having an input connected to an input transducer and each bandpass filter having an output connected to the input of one of a plurality of multiplicative AGC circuits whose outputs are summed together and connected to the input of an output transducer. The multiplicative AGC circuits attenuate acoustic signals having a constant background level without the loss of speech intelligibility. The identification of the background noise portion of the acoustic signal is made by the constancy of the envelope of the input signal in each of the several frequency bands. The background noise that will be suppressed includes multi-talker speech babble, fan noise, feedback whistle, florescent light hum, and white noise.
