a processor

Abstract

The invention discloses a processor. The processor includes an instruction queue storage area, a configuration information storage area, a decoding control unit, an explicit decoder and an implicit decoder. The instruction queue storage area stores a to-be-decoded instruction queue. The configuration information storage area stores decoding constraint information. The decoding control unit reads a plurality of instructions from the instruction queue storage area at the beginning of each decoding cycle to use the same as explicit instructions of the current decoding cycle, and controls the explicit decoder to decode the explicit instructions according to the decoding constraint information in the configuration information storage area; and uses the instructions, which remains in the explicit instructions after the explicit instructions are decoded by the explicit decoder, as implicit instructions of the next decoding cycle at the end of the current decoding cycle, and controls the implicit decoder to decode the implicit instructions in the next decoding cycle. According to the embodiment of the invention, multi-instruction decoding is realized through logic circuit devices, a decoding control flow which can be continuously executed is formed, a decoding design is optimized, and the efficiency of instruction decoding and execution is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a processor. Background technique [0002] Due to the rapid development of information technology, the importance of information security is increasing day by day. To keep information safe, processor security must be ensured. Security processor is a key technology in the field of information security. [0003] The current security processor mainly realizes the security processing of the processor by running encryption algorithm software. However, this kind of encryption algorithm has a high probability of being cracked, and the implementation of the encryption algorithm greatly reduces the overall performance of the processor. security has been unable to meet the actual needs. Contents of the invention [0004] In view of this, the present invention provides a processor to solve the above problems in whole or in part. [0005] A processor provided by the present inventio...
