subw Subtract word This instruction is defined by: Encoding Synopsis Subtract the 32-bit values in rs2 from rs1, and store the sign-extended result in rd Access M HS U VS VU Always Always Always Always Always Decode Variables Bits<5> rs2 = $encoding[24:20]; Bits<5> rs1 = $encoding[19:15]; Bits<5> rd = $encoding[11:7]; Execution Pruned, XLEN == 64 Original Bits<32> t0 = X[rs1][31:0]; Bits<32> t1 = X[rs2][31:0]; X[rd] = sext(t0 - t1, 31); Bits<32> t0 = X[rs1][31:0]; Bits<32> t1 = X[rs2][31:0]; X[rd] = sext(t0 - t1, 31);
