Abstract

The invention discloses an instruction set compatible method and terminal of a CPU, and solves the technical problem of poor user experience caused by unable run of numerous applications due to the fact that existing partial AMD CPUs cannot be compatible with an application of an SSSE3 instruction set. The instruction set compatible method of the CPU comprises the steps of obtaining a command of running an SSSE3 instruction application by an AMD CPU, and capturing an abnormal signal after the SSSE3 instruction application runs; and calling a preset abnormal handler function, judging whether the abnormal signal is the SSSE3 instruction or not, and if yes, simulating the SSSE3 instruction through a preset SSE1 instruction and a preset SSE2 instruction to enable the SSSE3 instruction application to run successfully.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a CPU instruction set compatibility method and a terminal thereof. Background technique [0002] AMD CPU is the only CPU manufacturer that can compete with Intel and has a wide range of applications. Intel uses x86, EM64T, MMX, SSE, SSE2, SSE3, SSSE3 (Super SSE3), SSE4.1, SSE4.2, AVX instruction set. AMD is mainly x86, x86-64, SSE, 3D-Now! Instruction Set. [0003] SSE (Streaming SIMD Extensions) is an instruction set introduced by Intel in its computer chip Pentium III and is a superset of MMX. AMD later added support for this instruction set in Athlon XP. This instruction set adds support for eight 128-bit registers XMM0-XMM7. SSE2 was introduced by Intel in the original version of P4, but AMD later added support for it in Opteron and Athlon64. This instruction set adds support for 64-bit double-precision floating-point numbers. SSSE3 is an extension of the SSE3 instru...
