It contains 57 instruction set, eight entries 64 bit vector registers (same MM0~MM7 register naming as used on the x86, the only difference being that i750 has dedicated registers while the x86 MMX CPU does not. However, the i750 lacks general purpose integer registers unlike its x86 counterpart), a 64-bit ALU, a 512×48-bit instruction RAM, a 512×16-bit data RAM, two internal 16-bit buses, a wide instruction word processor, a variable length sequence decoder, a pixel interpolator and an interface supporting a 4 GB linear address space.
