Template:mpu Atom Z620 is an ultra-low power 32-bit x86 system on a chip designed by Intel and introduced in early 2010. The Z620, which is based on the Bonnell microarchitecture (Lincroft core), is fabricated on a 45 nm process. This SoC incorporates a single core operating at 900 MHz with a low frequency mode of 600 MHz and a burst frequency of 1.5 GHz. The chip has a TDP of 1.3 W and supporting up to a 2 GiB of single-channel DDR2-800 memory. Additionally, the Z620 incorporates a GMA 600 IGP operating at 400 MHz.

This chip communicates with the southbridge chipset (PCH MP30) over two buses: cDMI and cDVO. Both buses go from the SoC to the chipset. cDMI, which is used as the data interface link, operates at 100 MHz using a quad-pumped rate (i.e. 400 MT/s). That bus is composed of an 8-bit transmit and 8-bit receive. The cDVO, which is used as a unidirectional display data link is a quad-pumped 6-bit bus operating 100 MHz for a 400 MT/s effective rate. This model uses CMOS signaling for both buses.

Cache

Main article: Bonnell § 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.
