System on chip for forming complex circuit on silicon chip, has transmitter circuit with data bus connecting receiver circuit`s input port to transmitter circuit`s output port, and two links connecting terminals of circuits

摘要

The chip has a transmitter circuit (2) with a validation circuit (24) to activate a validation signal based on the availability information representative of the memory space available in an input buffer of a receiver circuit (1). The circuit (2) has a data bus (3) connecting an input port (10) of the circuit (1) to an output port (21) of the circuit (2), a link (4) connecting an input terminal (11) of the circuit (1) to an output terminal (22) of the circuit (2), and another link (5) connecting an output terminal (13) of the circuit (1) to an input terminal (23) of the circuit (2). The information is updated at every transmission of a data word and at each reception of extraction information. An independent claim is also included for a method to transfer data between two circuits comprised in an integrated electronic circuit.
