An microprocessor apparatus and method are provided for executing native
instructions directly from memory. The apparatus includes instruction
translation logic and bypass logic. The instruction translation logic
retrieves macro instructions provided via an external instruction bus,
and translates each of the macro instructions into associated native
instructions for execution. If a first form of a first macro instruction
is retrieved, the instruction translation logic directs the
microprocessor to enable a native bypass mode and indicates such by
asserting a first bit within a control register. The bypass logic is
coupled to the instruction translation logic. The bypass logic accesses
the first bit within the control register to determine if the native
bypass mode has been enabled, and detects wrapper macro instructions and,
upon detection of the wrapper macro instructions, disables the
instruction translation logic, and provides the native instructions for
execution by the microprocessor, thereby bypassing the instruction
translation logic.
