一、芯片参数

RV1109

RV1109 is a high-performance AI vision processor SoC for IPC, or for other intelligent vision applications.

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.

The build-in NPU supports INT8/INT16 hybrid operation and computing power is up to 1.2TOPs. In addition, with its strong compatibility, network models based on a series of frameworks such as TensorFlow/MXNet/PyTorch/Caffe can be easily converted.

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.

The video encoder embedded in RV1109 supports 5M H.265/H.264 encoding. 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.

The H.264/H.265 video decoder in RV1109 supports 5M for H.264 and H.265.

RV1109 has high-performance external DRAM (DDR3/DDR3L/DDR4/LPDDR3/LPDDR4) capable of sustaining demanding memory bandwidths.
