Godson-2H (龙芯2H) is a 64-bit MIPS performance processor developed by ICT and later Loongson for desktop computers. Introduced in late-2010, the Godson-2H operates at up to 1 GHz consuming up to 10 W. This chip was manufactured on STMicroelectronics' 65 nm process.

The Godson-2H is actually a complete system on a chip incorporating the northbridge along with the southbridge on-die. Additionally the Godson-2H also incorporates a low-power Vivante GC800 IGP operating at 400 MHz.

In addition to a standalone SoC, the Godson-2H can also operate in slave-mode serving as a cooperative southbridge to the more powerful Godson 3 multi-core processor family.

[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.
