Embodiment

[0053] Below to image 3 The design of the shown FIR filter to specifically illustrate the implementation process of the entire invention patent is as follows:

[0054] image 3 is a 108-order FIR filter, where c 0 -c 107 is the coefficient of the FIR filter, x(n) is the input 16-bit data, and y(n) is the output result.

[0055] The coefficient and the data width of FIR filter are 16bits, then according to the data width requirement, select the remainder basis set, in the present embodiment, select the remainder basis of RRNS to be m 1 =15, m 2 =16,m 3 =17, m 4 =19,m 5 =23,m 6 =29, where m 5 = 23 and m 6 =29 is the redundant remainder base.

[0056] Among them, in the B2R module, the operation of x(n) for the remainder base of the selected RRNS is completed, that is The specific process is: 15 , 16 , 17 , 19 , 23 and 29 . The remainder operation is a well-known technology in this field, and will not be described in detail here.

[0057] Among them, t...

Abstract

The invention relates to a redundant-residue-number-system (RRNS)-based irradiation-resisting reinforcing method, which is characterized in that: the method is based on the reinforcing framework of an RRNS, and the redundant numbers of the RRNS can participate in operation. The method mainly comprises the following steps of: converting binary operands into the operands of the RRNS, performing a calculation and correcting errors. Due to the data route of a new RRNS-based design framework, the irradiation-resisting performance of the system is ensured, and the overhead of the system can be lowered compared with those of the conventional system.

Description

technical field [0001] The invention belongs to the field of integrated circuit design of microelectronics, such as the anti-radiation reinforcement technology in avionics, and in particular relates to a design method for aviation specific integrated circuits. Background technique [0002] In the previous process, due to the large node capacitance of integrated circuits, high operating voltage, and low operating frequency, single event transient pulse effects (Single Event Transients, SETs) lead to single event upset effects (Single Event Upsets, SEUs) The proportion is small, basically not considered, and the SEUs effect generated by the sequential logic device itself is mainly considered. However, with the advancement of technology, the improvement of integration, the reduction of operating voltage, the reduction of node capacitance and the increase of operating frequency, the proportion of SEUs caused by SETs increases, which can no longer be ignored. Many scholars at ho...
