The CN3830-400 EXP is a 64-bit quad-core MIPS communication microprocessor designed by Cavium and introduced in 2005. This processor, which incorporates four cnMIPS cores, operates at 400 MHz. This processor includes a number of hardware networking accelerators including units for high-performance packet I/O processing, QoS, TCP, and RegEx. This MPU supports up to 16 GiB of DDR2-800 ECC memory.
- Main article: cnMIPS § Cache
[Edit/Modify Cache Info]
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.
