功能特点
•ATM7029为炬力集成电路设计有限公司最新发布的多核架构”猫头鹰系列”（OWL)的第一颗芯片。该芯片集成了自主创新的第一代Leopard CPU，源自ARM Cortex A9 Family IP授权，内置多核3D GPU , 采用独特的“LPD Gen II”（第二代低功耗设计）和”ADP”（自适应动态功耗）架构,突破“高性能=高功耗”的限制，让用户在体验四核高性能畅玩的同时获得超长续航能力。
•ATM7029芯片是炬力针对多核平板市场推出的第一款四核、高集成度、高性能、低功耗的主控芯片。这款芯片除了具有高性能多核CPU和3D GPU外，还内建了独立的VE(Video Engine)引擎和ISP(Image Signal Processing)引擎,从而具有强大的视频回放和录制能力，最大视频解码能力可达1080P 60fps，最大视频录制能力达1080P 30fps。
•基于ATM7029芯片的平板解决方案由于芯片的高集成度，为广大客户提供了非常具有竞争力的BOM(Bill of Material)成本。该芯片集成了平板产品必需的LVDS以及HDMI接口，同时集成了DDR3/DDR3L存储控制器以及支持最新世代60bit ECC以及Toggle接口nandflash存储器。ATM7029通过和自主研发的ATC2603A芯片(集成了PMU和Audio Code)的搭配使用，为平板电脑产品提供了一个高性价比和竞争力的解决方案。
