Now, the field of mobile processors, we are concerned about most is Texas Instruments, Qualcomm, Spreadtrum, MTK, even including Intel, Freescale, but please do not forget, he's i.MX processors have been developed to the sixth generation.
So we have to take stock under i.MX today it past lives.
i.MX Past: DragonBall
Now I mention DragonBall, perhaps most people thought it was Dragon Ball nostalgia. But really, the time Dragon Ball appeared earlier than Motorola's DragonBall (ie MC68328). Dragon Ball began writing in 1984, while DragonBall appeared in 1995, was designed by Motorola internship was in electronic engineering students of the City Polytechnic of Hong Kong.
We can see from the name, MC68328 Motorola 68000-based core, but power consumption of this product compare with similar products, low power consumption, making it ideal for handheld devices.
And this is a the SoC, which includes a display controller (Display controller), Universal Asynchronous Receiver Transmitter (the UART), infrared data transfer (the IrDa), real-time clock (RTC) and the like, saving chip space, cost and power consumption .
DragonBall MC68328 and DragonBall EZ (MC68EZ328) processing speed of 16.58MHz, performance to 2.7 MIPS. An upgraded version of DragonBall VZ (MC68VZ328) the frequency of 33MHz, performance 5.4MIPS, and DragonBall Super VZ (MC68SZ328) performance and doubling, 66MHz clock speed, performance 10.8MIPS.
DragonBall processor called one of the most classic of the year, Palm, Handspring, Albert Henderson, Lenovo, Founder and Hanwang, have been adopted DragonBall processor.
Regime change: i.MX
Since DragonBall MX series, Motorola began to abandon 68000 ARM core and comprehensive shift, then, Intel, TI and other mobile processors based on the ARM core ARM has begun to turn, and have achieved good results.
After turning ARM, product name has officially changed its name to the i.MX family, Innovative Multimedia eXtension , which means innovative multimedia extensions experience. Including Ford, Amazon, Sony, Logitech, Toshiba, Nokia, Motorola, iRiver, and now e people e, we have adopted the i.MX family of processors.
i.MX1 series, based on the ARM920T, frequency from 100MHz to 200MHz.
i.MX2 series, based on ARM9, processing the frequency 400MHz, 454MHz, 90nm process, comprising industrial and automotive-grade product, having a video processing unit, a security control unit, a liquid crystal touch driving, power management, audio decoding, Can / Ethernet interface, support for DDR.
i.MX3 Series: ARM11,90nm based process, the processing frequency 532MHz, with video decoding, 3D graphics processing unit.
i.MX5 Series: ARM Cortex-A8,65nm based process, the processing speed is greater than 800 MHz, support 720P hard decoding, DDR2, supporting electronic ink display driver.
i.MX6 series: based on ARM Cortex A9, supports single, dual-, and quad-core, using 40nm process, support for high-definition video decoding.
