sentences:  The internal pipeline of the V80 seemed buffered asynchronous, but that of i486 was synchronous.In other words, the internal microarchitecture of V80 was CISC, but that of i486 was RISC.Both of their ISAs allowed long non-uniform CISC instructions, but the i486 had a wider, 128-bit internal cache memory bus, while that of V80 had a 32-bit width.
