What in the world is this?!

Ingenic have been hard at work by the looks of it, their website shows details of a new SoC released on Jun 4th – the JZ4770. This is at least 3 generations from the JZ4750 found in our beloved Dingoo A320, and this time promises OpenGL ES1.0 and 2.0 3D acceleration, coupled with an Xburst 1Ghz CPU, support for DDR2 memory and a bunch of other stuff that makes not a jot of sense to me. Read on to see what they have to say about it:

    JZ4770 is a mobile application processor targeting for multimedia rich and mobile devices like smartphone, tablet computer, mobile digital TV, and GPS. This SOC introduces a kind of innovative architecture to fulfill both high performance mobile computing and high quality video decoding requirements addressed by mobile multimedia devices. JZ4770 provides high-speed CPU computing power, good 3D experience and fluent 1080p video replay.

    The CPU (Central Processing Unit) core, equipped with 16kB instruction and 16kB data level 1 cache, and 256kB level 2 cache, operating at 1000MHz, and full feature MMU function performs OS related tasks. At the heart of the CPU core is XBurst processor engine. XBurst is an industry leading microprocessor core which delivers superior high performance and best-in-class low power consumption. A hardware floating-point unit which compatible with IEEE754 is also included.
    The VPU (Video Processing Unit) core is powered with another XBurst processor engine. The SIMD instruction set implemented by XBurst engine, in together with the on chip video accelerating engine and post processing unit, delivers high video performance. The maximum resolution of 1080p in the formats of H.264, VC-1, MPEG-2, MPEC-4, RealVideo and VP8 are supported in decoding, the maximum resolution of 720p in the format of H.264 are supported in encoding.

    The GPU (Graph Processing Unit) core supports numerous 2D/3D graphics applications. It delivers hardware acceleration for 2D and 3D graphics displays, and supports screen sizes range from the smallest cell phones to full HD 1080p displays. It supports the standard APIs such as OpenGL ES2.0 and 1.1, and Open VG. The OS of Android, Linux and Windows are supported. The GPU provides high performance, high quality graphics and low power consumption.

    The memory interface supports a variety of memory types that allow flexible design requirements, including glueless connection to SLC NAND flash memory or 4-bit/8-bit/12-bit/16-bit/24-bit ECC MLC/TLC NAND flash memory for cost sensitive applications. It provides the interface to DDR2, DDR and LPDDR memory chips with lower power consumption.

    On-chip modules such as audio CODEC, multi-channel SAR-ADC, AC97/I2S controller and camera interface offer designers a rich suite of peripherals for multimedia application. GPS baseband is embedded. TV encoder unit 10-bits DAC provide composite TV signal output in PAL or NTSC format. The LCD controller support up to 1920×1080 output, LVDS as well as plain RGB output which support external HDMI transmitter. The EPD controller supports mainstream vendors’ EPD panels in market, up to 5-bit grayscale and 8-zone concurrent updating. WLAN, Bluetooth and expansion options are supported through high-speed SPI and MMC/SD/SDIO host controllers. The TS (Transport stream) interface provides enough bandwidth to connect to an external mobile digital TV demodulator. Other peripherals such as USB OTG and USB 1.1 host, Ethernet MAC with MII and RMII interface, UART and SPI as well as general system resources provide enough computing and connectivity capability for many applications.

Earth has a lot of things other folks might want... like the whole planet. And maybe these folks would like a few changes made, like more carbon dioxide in the atmosphere and room for their way of life. - William S. Burroughs
