ARMADA 628 was a 32-bit tri-core ARM microprocessor introduced by Marvell in 2011. This processor, which is based on Marvell's Sheeva PJ4 microarchitecture, operated at 1.5 GHz for the 2 big cores with lower frequency for the third low-power core. The 628 supported up to 2 GiB of DDR3-1066 memory and integrated a Vivante GC1000 IGP.

The ARMADA 628 featured three heterogeneous cores - two identical large powerful cores operating at 1.5 GHz each with a third lower power core which operated at just 624 MHz whenever lightweight work was done which helped save power.

[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.
