Template:mpu The CN3010-300 SCP is a 64-bit single-core MIPS secure communication microprocessor (SCP) designed by Cavium and introduced in early 2006. This processor, which incorporates a single cnMIPS core, operates at 300 MHz and dissipates 2 Watts. This processors includes a number of hardware security communication accelerators including units for encryption, QoS, and TCP acceleration. This MPU supports up to 2 GiB of DDR2-533 ECC memory. This model includes double as much cache as the CN3005 equivalent, double DDR2 memory access, as well as support for TDM/PCM (VoIP support).

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.
