Abstract
A data processor (10) having an instruction fetch unit (12), a decode and control unit (14), and an execution unit 16 performs conditionally executed instructions in hardware. A conditional break instruction, BRKcc, is inserted within a looping instruction to conditionally terminate the looping instruction with a minimum number of instruction cycles. A conditional do-loop instruction, DO#0, prevents the data processor (10) from executing a do-loop with a loop count within a loop counter (24) of zero upon entry. A conditional repeat instruction, REP#0, prevents a repeat instruction from being executed if a loop count is zero upon entry. A conditional repeat instruction, REPcc, allows a subsequent instruction to be conditionally terminated during execution.
