DESCRIPTION:Historically\, many architectures have attempted to run ILP32 s
 oftware on 64-bit ISAs\, such as x86-X32\, mips-N32\, and arm64-ILP32. How
 ever\, only arm64ilp32 achieved commercial success on Apple Watch OS in a 
 closed-source manner.\n\nToday\, we present the commercial deployment of R
 V64-ILP32 based on Allwinner v861 AI Glasses chips (Dual-Core RISC-V XuanT
 ie C907) [1]. This demo showcases AI Glasses running the ILP32 Linux kerne
 l on RVA22S64. Compared to traditional RV32\, performance improves signifi
 cantly: iperf throughput reaches 1.5×\, and lmbench shows 1.1–1.2× gai
 ns across most tests. Furthermore\, another demo runs LP64 applications on
  an RV64-ILP32 Linux kernel within a 2GB address space for the first time\
 , highlighting this ABI's compatibility\, flexibility\, and potential. Thi
 s demo achievement marks a milestone in bringing 64-bit RISC-V architectur
 al benefits to resource-constrained embedded AI devices while maintaining 
 ILP32 memory efficiency based on an open-source software stack.\n\n[1]: ht
