Abstract: A field programmable gate array (FPGA) with an automatic error detection and correction function for programmable logic modules includes an error checking and correction device. A check code generation circuit in the error checking and correction device performs error correcting code (ECC) encoding according to input data of corresponding programmable logic registers to generate a check code, and refreshes and writes the check code into a check code register according to a clock signal. A check circuit checks outputs of the programmable logic registers and check code registers to generate syndromes for implementing checking. A decoding circuit generates upset signals corresponding to the syndromes according to a trigger enable pulse of a trigger circuit to control a fault register to directly and asynchronously upset content to correct the error. A circuit area is greatly reduced by using the FPGA, thereby improving a degree of integration of the circuit.

Abstract: The present disclosure discloses an FPGA device for implementing a network-on-chip transmission bandwidth expansion function, and relates to the technical field of FPGAs. When a predefined functional module with built-in hardcore IP nodes is integrated in an FPGA bare die, soft-core IP nodes are configured and formed by using logical resource modules in the FPGA bare die and are connected to the hardcore IP nodes to form an NOC network structure, so as to increase nodes and expand the transmission bandwidth of the predefined functional module. On the other hand, the soft-core IP nodes can be additionally connected to input and output signals in the predefined functional module and also can expand the transmission bandwidth of the predefined functional module.
