![]() ![]() LoongArch includes a reduced 32-bit version (LA32R), a standard 32-bit version (LA32S) and a 64-bit version (LA64)". A Loongson developer described it as ".a new RISC ISA, which is a bit like MIPS or RISC-V. Loongson moved to their own processor instruction set architecture (ISA) in 2021 with the release of the Loongseries. The new instructions help a QEMU hypervisor translate instructions from x86 to MIPS with only a reported 30% performance penalty. The binary translation instructions have the specific benefit of speeding up Intel x86 CPU emulation at a cost of 5% of the total die area. The LoongISA instructions were introduced as part of the GS464E cores. MIPS SIMD Architecture (MSA), DSP, and VZ modules from MIPS Release 5.LoongSIMD, formerly LoongMMI (in Loongson 2E/F), for 128-bit SIMD, 1014 instructions. ![]()
