Template:mpu The CN3120-400 SCP is a 64-bit dual-core MIPS secure communication microprocessor (SCP) designed by Cavium and introduced in 2006. This processor, which incorporates two cnMIPS cores, operates at 400 MHz. 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.

Cache Organization
Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory. The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC. Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies. Note: All units are in kibibytes and mebibytes. |
