The '''CN3860-500 EXP''' is a {{arch|64}} [[hexadeca-core]] [[MIPS]] communication [[microprocessor]] designed by [[Cavium]] and introduced in [[2005]]. This processor, which incorporates sixteen {{cavium|cnMIPS|l=arch}} cores, operates at 500 MHz. This processor includes a number of hardware networking accelerators including units for high-performance packet I/O processing, QoS, TCP, and RegEx. This MPU supports up to 16 GiB of DDR2-800 ECC memory.
