Vector unit-stride operations access elements stored contiguously in memory starting from the base effective address. It can been seen as a special case of strided operations.

The only way to use vector extension is 1. use cpu rv32 or rv64 2. turn on it by command line "-cpu rv64,x-v=true,vlen=128,elen=64,vext_spec=v0.7.1". vlen is the vector register length, default value is 128 bit. elen is the max operator size in bits, default value is 64 bit. vext_spec is the vector specification version, default value is v0.7.1. These properties can be specified with other values.
