However, the performance is nearly always subscalar (less than one instruction per clock cycle, IPC < 1 ). Source: Internet
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 ). Source: Internet
