UMOV

Unsigned Move vector element to general-purpose register. This instruction reads the unsigned integer from the source SIMD&FP register, zero-extends it to form a 32-bit or 64-bit value, and writes the result to the destination general-purpose register.

Depending on the settings in the CPACR_EL1, CPTR_EL2, and CPTR_EL3 registers, and the current Security state and Exception level, an attempt to execute the instruction might be trapped.

This instruction is used by the alias MOV (to general).

integer d = UInt(Rd); integer n = UInt(Rn); integer size; case Q:imm5 of when '0xxxx1' size = 0; // UMOV Wd, Vn.B when '0xxx10' size = 1; // UMOV Wd, Vn.H when '0xx100' size = 2; // UMOV Wd, Vn.S when '1x1000' size = 3; // UMOV Xd, Vn.D otherwise UNDEFINED; integer idxdsize = if imm5<4> == '1' then 128 else 64; integer index = UInt(imm5<4:size+1>); integer esize = 8 << size; integer datasize = if Q == '1' then 64 else 32;
