The 68020 has a coprocessor interface supporting up to eight coprocessors. The remaining coprocessors gained instructions to move doublewords between coprocessor registers and the GPRs. UltraSPARC T2 and T3's per-core cryptographic coprocessors were replaced with in-core accelerators and instruction-based cryptography. Some of these chips have coprocessors also include cores from the older 32-bit architecture (ARMv7). The chipset bus allows the custom coprocessors and CPU to address "Chip RAM". It comes ready to emulate an ARM processor and certain ARM coprocessors. The SPUs are themselves vector coprocessors. MIPS is a modular architecture supporting up to four coprocessors (CP0/1/2/3). It is sometimes associated with a Truespeech trademark in coprocessors produced by DSP Group. Separately packaged mathematics coprocessors are now uncommon in desktop computers. Other Intel coprocessors were the 80287, 80387, and the 80187. The onboard computers were upgraded with added coprocessors, and Hubble's orbit was boosted. One of the hardware coprocessors in the Amiga personal computer is a blitter. On August 19, 2012, Adapteva posted some specifications and information about Epiphany multi-core coprocessors. User-defined coprocessors are supported through dedicated AXI4-Stream connections.
