Examples
Naturally, accomplishing this requires additional circuitry, so pipelined processors are more complex than subscalar ones (though not very significantly so).
However, the performance is nearly always subscalar (less than one instruction per clock cycle, IPC < 1 ).
This type of CPU, usually referred to as subscalar, operates on and executes one instruction on one or two pieces of data at a time, that is less than one instruction per clock cycle ( IPC < 1 ).
