Device for the functional reproduction of a specific intergrated circuit and its usage as an emulation device

摘要

The modules include; (a) a processor (12) identical to that in the specific integrated circuit; (b) a number of peripherals (14,16,18) each of which can perform one or more numeric and/or analogue functions, each of which can be separately selected, and; (b) a function interconnection module (20) for making connections between the processing module and the selected function modules. The functions are identical to those in the specific integrated circuit. Real time modular operational reproduction system (10) for a specific integrated circuit composed of a processing unit and specific numeric and/or analogue functions under the control of a specific program. The specific integrated circuit is designed to be incorporated in a determined application card. The function interconnection module (20) is connected to the processing module by an internal bus (28) connecting the internal connections of the specific integrated between its processing unit and its peripherals. The peripheral modules include one or more integrated circuits (14,16) each specially conceived to implement a number of numeric and/or analogue functions. The peripheral modules also include one or more programmable logic networks of the Field Programmable Gate Array type (18) which have been preprogrammed so that they implement at least a pre-selected numeric function which cannot be implemented by the integrated circuits (14,16). The module (20) is configured by a programmable automaton (44) by means of a program actuated when the numeric and/or analogue functions must be implemented by the selected peripheral modules.
