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