Template:mpu The CN3005-300 CP is a 64-bit single-core MIPS communication microprocessor (CP) designed by Cavium and introduced in 2005. This processor, which incorporates a single cnMIPS core, operates at 300 MHz and dissipates 2 Watts. This processors includes a number of hardware communication accelerators including units for high-performance packet I/O processing, QoS, and TCP acceleration.
Cache
- Main article: cnMIPS § Cache

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. |
