君正X1830芯片性能和处理器介绍
简介：
君正X1830是一款针对物联网市场的处理器，面向诸如智能音箱，智能网关，语音面板等智能家居领域，以及人脸识别，专业安防，视频会议等行业领域。使用了创新的XBurst架构，可以满足高性能运算以及高质量的图像和视频编码需求。
该CPU采用了32KB+32KB的L1高速缓存以及128KB的L2高速缓存，主频1.5GHz，全功能MMU功能执行与OS相关的TASKs。CPU内核的核心部分是XBurst®处理器引擎。XBurst®是行业领先的微处理器内核，可提供高性能和极低功耗。还包括一个与IEEE754兼容的硬件浮点单元。MXU2.0(SIMD128) 指令集已由XBurst®引擎实现，成为CPU的其中一部分。
凭借功能强大的CPU，X1830支持各种计算机视觉应用，例如人脸检测，人形检测，手势识别等等。你也可以开发新的计算机视觉应用程序，并利用MXU2.0并对其进行加速。
VPU（视频处理单元）内核由另一个XBurst®处理器引擎控制。 结合片上视频加速引擎和后处理单元，X1830提供了出色的视频性能。 编码支持H.264格式的最大分辨率1560x1600，码率达到最高50Mbit / s，1080P @ 80fps。
ISP（图像信号处理）内核对来自图像传感器的图像，进行出色的图像处理。它支持DVP，MIPI，CSI-2和LVDS接口。 借助3A，2D和3D去噪，WDR / HDR，镜头暗影等功能，它可支持查看/编码最大分辨率为2699x2048的图像，并进行存储和传输。
同时为了让工程师能更快更容易地上手X1830，我们给它内置了1024Mbits 的DDR2内存。我们也为工程师提供了一套较为经济的视频应用外设，比如音频编解码器，多通道SAR-ADC控制器和摄像头接口。通过高速SPI和MMC / SD / SDIO主机控制器支持包括WLAN，蓝牙和扩展选项。 USB OTG，UART和SPI等其他外设以及通用系统资源为许多应用程序提供了运算和拓展能力。
