Integrated circuit having programmable analog functions and computer aided techniques for programming the circuit

摘要

A number of analog circuit modules are assembled on a single integrated circuit chip with the ability of the user to program, through pins of the circuit, certain functions and operational parameters of the individual modules, and to interconnect the modules in a specified way in order to form a desired analog system on the single circuit. Support and diagnostic modules are also included. The individual modules are configured, and those forming the analog circuit interconnected together, by configuration data that is loaded into a series connection of configuration registers. Individual ones of the configuration registers are separately addressable, however. The interface characteristics of the individual signal modules are made such that they may be connected together in a number of different combinations without affecting operation of the individual modules.
