The CN3630-600 NSP is a 64-bit quad-core MIPS network service microprocessor (NSP) designed by Cavium and introduced in 2005. This processor, which incorporates four cnMIPS cores, operates at 600 MHz. This processor includes a number of hardware networking accelerators including units for high-performance packet I/O processing, QoS, TCP, encryption, and RegEx. This MPU supports up to 16 GiB of DDR2-800 ECC memory.

Cache

Main article: cnMIPS § Cache

[Edit/Modify Cache Info]

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.
