Input (grade 11): While early superscalar CPUs would have two ALUs and a single FPU, a modern design such as the PowerPC 970 includes four ALUs, two FPUs, and two SIMD units.
Output (grade 10): As of 2008 all general-purpose CPUs are superscalar, a typical superscalar CPU may include up to 4 ALUs, 2 FPUs, and two SIMD units.
