Design verification method of special instruction processor

Abstract

The invention discloses a design verification method of a special instruction processor. The method comprises the following steps: optimizing a target algorithm; dividing the target algorithm into a plurality of basic instruction blocks; converting the basic instruction blocks into a data flow diagram, and searching optimizable instruction blocks from the basic instruction blocks according to a preset instruction design rule by adopting a method of approximate optimal solution; designing special instructions of the searched optimizable instruction blocks and extending an original instruction set; and establishing a special instruction processor model and carrying out simulation verification on the special instruction processor model. According to the design verification method of the special instruction processor, the operating speed of the target algorithm for executing the modules with relatively high complexity in the realization process is improved through an instruction set extension method, so that the execution efficiency of the algorithm is improved.

Description

technical field [0001] The invention relates to the field of embedded technology, in particular to a design verification method of a special instruction processor. Background technique [0002] Compared with other public key cryptographic algorithms, Elliptic Curve Cryptography (ECC) has the advantages of strong anti-attack ability, small amount of calculation and fast processing speed, and has become the standard of the next generation of public key cryptosystem. Compared with the widely used public key cryptographic algorithm RSA, the key strength required by ECC is only 1 / 6 of RSA under the same security strength. That is, for the ECC on the q-element finite field, when q is 160bit (the modulus is still safe), RSA needs a modulus of 1024bit to achieve the same security strength. This advantage enables ECC to obtain faster processing speed, less network bandwidth and storage space requirements, and has greater potential use value in practical applications. [0003] The p...
