...9;t have to be any explicit status register. You can either create separate instructions for each condition, or have the condition as an extra operand. Let's take "add" for example. You could have several versions of add: add add unconditionally addc add if carry addz add if zero addo add if overflow and similarly for more complex conditions that your target could support, such as "carry or zero". This has the disadvantage that the instruction set can get really large, but if the number of conditional instructions is small or if the possib...

Many thanks for your prompt reply. I mean, imagine you have 3 bits for condition flags in your instruction (e.g. overflow, zero, carry set, ...) for conditional executions AND there is no direct access to the Status Register, is it even possible to implement such scenario?
