lxsw
Load scaled indexed word
This instruction is defined by:
Synopsis
Load 32 bits of data into register xd from the effective address
X[xs2] + (X[xs1] << 2), where xs2 is the base and xs1 is the index.
On RV64, the loaded word is sign-extended to 64 bits.
Decode Variables
Bits<5> xs2 = $encoding[24:20];
Bits<5> xs1 = $encoding[19:15];
Bits<5> xd = $encoding[11:7];Execution
