TSK3000A - Comparison Instructions
These instructions compare two registers and, based on the result, set a third register to either true or false (1 or 0).
Table 1. Comparison Instructions.| Mnemonic | Instruction | Description |
|---|---|---|
SLT rC, rA, rB | Set On Less Than | Compares the contents of GPRs rB and rA as 32-bit signed integers. If rA is less than rB, a '1' is placed into GPR rC, otherwise GPR rC is loaded with '0' |
SLTI rB, rA, IMM16 | Set On Less Than Immediate | Sign-extends the 16-bit immediate value, IMM16 and compares the result with the contents of GPR rA, treating both values as 32-bit signed integers. If rA is less than the sign extended IMM16 value, a '1' is placed into GPR rB, otherwise GPR rB is loaded with '0' |
SLTIU rB, rA, IMM16 | Set On Less Than Immediate Unsigned | Sign-extends the 16-bit immediate value, IMM16 and compares the result with the contents of GPR rA, treating both values as 32-bit unsigned integers. If rA is less than the sign extended IMM16 value, a '1' is placed into GPR rB, otherwise GPR rB is loaded with '0' |
SLTU rC, rA, rB | Set On Less Than Unsigned | Compares the contents of GPRs rB and rA as 32-bit unsigned integers. If rA is less than rB, a '1' is placed into GPR rC, otherwise GPR rC is loaded with '0' |
