The early arm chips were named after the ' arm ' prefix, such as ARM7, ARM9, ARM11, and, presumably, from 08 onwards, renamed ' CORTEX ' as a prefix, such as CORTEX-A8, cortex-a9, such as:
With the progress of technology, the chip manufacturing process is becoming more and more sophisticated, the cost is getting lower and the power control is getting better, such as:
The introduction of CORTEX-A9 has enabled the ARM processor to achieve the unprecedented high, mature and stable multicore technology, which has led to a revolutionary improvement and user experience for embedded devices.
Samsung, Qualcomm, Nvidia, Freescale and other companies have released their own cortex-a9 chip, of which Samsung's Exynos 4412 is undoubtedly the most successful processor, the accumulation of billions of pieces of sales, making the cost greatly reduced, Exynos 4412 excellent performance, And the stability of reliability in the market has also been fully tested.
The EXYNOS4412 processor has two packages, the SCP package and the POP package, the difference between the two packages, such as:
And Schindler for the two packaging design corresponding core board, convenient for everyone to choose.
