Template:mpu The CN3005-500 CP is a 64-bit single-core MIPS communication microprocessor (CP) designed by Cavium and introduced in 2006. This processor, which incorporates a single cnMIPS core, operates at 500 MHz and dissipates 4 Watts. This processors includes a number of hardware communication accelerators including units for high-performance packet I/O processing, QoS, and TCP acceleration. This MPU supports up to 2 GiB of DDR2-533 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.
