The Mx4000VME is a 4-axis, DSP-based motion controller. The Mx4 is powered by a multi-DSP parallel processing architecture.

The Mx4000VME is a slave; it decodes 16 address lines and responds to data transfers at both even and odd address locations. The card also supports seven interrupt lines. The VME Mx4 card can be programmed to respond to short I/O address bus cycles, as determined by the address modifier bits AM5:0.

Its programming support includes a C-like programming language (DSPL) which utilizes the Mx4's DSP processing power, enabling the controller to perform computer, PLC, and motion controller functions in factory automation applications.
