c.sd
Store double
This instruction is defined by:
Synopsis
Stores a 64-bit value in register rs2 to memory.
It computes an effective address by adding the zero-extended offset, scaled by 8,
to the base address in register rs1.
It expands to sd rs2, offset(rs1).
Decode Variables
Bits<8> imm = {$encoding[6:5], $encoding[12:10], 3'd0};
Bits<3> rs2 = $encoding[4:2];
Bits<3> rs1 = $encoding[9:7];Execution
