| | Great Microprocessors of the Past and Present (V 13.4.0) |
 | | Applications for coprocessors at the time were limited, but the design is still used in some modern processors, such as the National Semiconductor 320xx series, which included FPU, MMU, and other coprocessors that could just be added to the CPU's coprocessor bus in a chain. |
 | | It consisted of at least four separate chips, including the control circuitry unit, the ALU, two or four ROM chips with customisable microcode (like the old 4-bit Texas Instruments TMS 1000), and timing circuitry. |
 | | Registers were expanded to 32-bits, four 64 bit floating point registers, virtual memory, and complex instructions (including a set to skip next instruction based on operation results, a primitive type of predicated instructions) were added in the MV series (1978/79) (Originally MV/Eclipse, renamed MV/8000). |
