The '''CN3120-550 NSP''' is a {{arch|64}} [[dual-core]] [[MIPS]] network service [[microprocessor]] (NSP) designed by [[Cavium]] and introduced in [[2006]]. This processor, which incorporates a two {{cavium|cnMIPS|l=arch}} cores, operates at 555 MHz and dissipates 7 Watts. This processor includes a number of hardware accelerators for network services such as [[encryption]], [[compression]] & decompression, [[RegEx]] engine, [[TCP]], and [[QoS]]. This MPU supports up to 4 GiB of 64-bit DDR2-667 ECC memory.
