1.1 Overview

RV1126 is a high-performance vision processor SoC for IPC/CVR, especially for AI-related applications. It is based on a 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 a 512KB unified L2 cache. The build-in NPU supports INT8/INT16 hybrid operation and computing power is up to 2.0TOPs. In addition, with its strong compatibility, network models based on a series of frameworks such as TensorFlow/MXNet/PyTorch/Caffe can be easily converted.<br>

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.

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. With the help of this feature, the video from the camera can be encoded with higher resolution and stored in local memory and transferred to another lower resolution video to cloud storage at the same time. The H.264/H.265 video decoder in RV1126 supports 4Kp30 for H.264 and H.265.

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 the whole system to improve flexibility and expansibility.

RV1126 has high-performance external DRAM (DDR3/DDR3L/DDR4/LPDDR3/LPDDR4-2133) capable of sustaining demanding memory bandwidths.

Support level trigger and edge trigger interrupt

Support configurable polarity of level trigger interrupt

Support configurable rising edge, falling edge, and both edge trigger interrupt

Support configurable pull direction (a weak pull-up and a weak pull-down)

<strong>RV1126 Datasheet Rev 1.4</strong>

Support configurable drive strength

Temperature Sensor (TS-ADC)

Support User-Defined Mode and Automatic Mode

In User-Defined Mode, start_of_conversion can be controlled completely by software, and also can be generated by hardware.

In Automatic Mode, the temperature of alarm(high/low temperature) interrupt can be configurable

In Automatic Mode, the temperature of the system reset can be configurable

Support to 2 channel TS-ADC (used for CPU and NPU respectively), the temperature criteria of each channel can be configurable

-40~125°C temperature range and 5°C temperature resolution

12-bit SAR ADC up to 732 S/s sampling rate

Successive approximation ADC (SAR ADC)

10-bit resolution

Up to 1MS/s sampling rate

6 single-ended input channels


Support 32Kbit space and higher 4k address space is a non-secure part.

Support read and program word mask in a secure model

Support program length from 1 to 32 bit

Read operation support 8bit only

Program and Read state can be read

The program fails to address the record
