<h1>一、芯片参数</h1>
<h3>RV1109</h3>
<p>RV1109 is a high-performance AI vision processor SoC for IPC, or for other intelligent vision applications.</p>
<p>It is based on Dual-core ARM Cortex-A7 32-bit core which integrates NEON and FPU. There is a 32KB I-cache and 32KB D-cache for each core and 512KB unified L2 cache.</p>
<p><font color=red size=3>The build-in NPU supports INT8/INT16 hybrid operation and computing power is up to 1.2TOPs.</font> In addition, with its strong compatibility, network models based on a series of frameworks such as TensorFlow/MXNet/PyTorch/Caffe can be easily converted.</p>
<p>RV1109 also introduces a new generation totally hardware-based 5-megapixel ISP (image signal processor) and post processor. It implements a lot of algorithm accelerators usually used in IPC and CVR, such as HDR, 3A functions (AE, AF, AWB), LSC, 3DNR, 2DNR, sharpening, dehaze, fisheye correction, gamma correction, feature points detection and so on. All of them are real-time processing. Cooperating with two MIPI CSI (or LVDS/SubLVDS) and one DVP (BT.601/BT.656/BT.1120) interface, users can build a system that receives video data from 3 camera sensors simultaneous.</p>
<p><font color=red size=3>The video encoder embedded in RV1109 supports 5M H.265/H.264 encoding. </font>It also supports multi-stream encoding, up to one 5M30FPS and one 720P30 simultaneous. With the help of this feature, the video from camera can be encoded with higher resolution and stored in local memory and transferred another lower resolution video to cloud storage at the same time.</p>
<p>The H.264/H.265 video decoder in RV1109 supports 5M for H.264 and H.265.</p>
<p>RV1109 has high-performance external DRAM (DDR3/DDR3L/DDR4/LPDDR3/LPDDR4) capable of sustaining demanding memory bandwidths.</p>
<h3>RV1126</h3>
<p>RV1126 is a high-performance vision processor SoC for IPC/CVR, especially for AI related application.</p>
<p>It is based on quad-core ARM Cortex-A7 32-bit core which integrates NEON and FPU. There is a 32KB I-cache and 32KB D-cache for each core and 512KB unified L2 cache.
<font color=red size=3>The build-in NPU supports INT8/INT16 hybrid operation and computing power is up to 2.0TOPs.</font> In addition, with its strong compatibility, network models based on a series of frameworks such as TensorFlow/MXNet/PyTorch/Caffe can be easily converted.</p>
<p>RV1126 also introduces a new generation totally hardware-based 14-megapixel ISP (image signal processor) and post processor. It implements a lot of algorithm accelerators usually used in IPC and CVR, such as HDR, 3A functions (AE, AF, AWB), LSC, 3DNR, 2DNR, sharpening, dehaze, fisheye correction, gamma correction, feature points detection and so on. All of them are real-time processing. Cooperating with two MIPI CSI (or LVDS/SubLVDS) and one DVP (BT.601/BT.656/BT.1120) interface, users can build a system that receives video data from 3 camera sensors simultaneous.</p>
<p><font color=red size=3>The video encoder embedded in RV1126 supports UHD H.265/H.264 encoding. It also supports multi-stream encoding, up to one 4Kp30 and one 1080p30 simultaneous. </font>With the help of this feature, the video from camera can be encoded with higher resolution and stored in local memory and transferred another lower resolution video to cloud storage at the same time.</p>
<p><font color=red size=3>The H.264/H.265 video decoder in RV1126 supports 4Kp30 for H.264 and H.265.</font>
In addition to the previous high-performance multimedia block, RV1126 also contains rich audio, memory and other peripheral interfaces such as I2C, SPI, PWM and so on. These can help users add more sensors or other peripherals into whole system to improve flexibility and expansibility.</p>
<p>RV1126 has high-performance external DRAM (DDR3/DDR3L/DDR4/LPDDR3/LPDDR4) capable of sustaining demanding memory bandwidths.</p>
