Last year, Rockchip had a presentation in China where they highlighted their processor roadmap for 2020, and we learn about processors such as Rockhip RK3588 Cortex-A76/A55, RK3530 Cortex-A55 SoC’s, and RV1109 camera processor, but we had limited details about the processors at the time.
CNX Software has now received a more detailed roadmap that reveals some of the specifications about the new processors, and some Rockchip products that people may not be aware of such as a 3D structured light module and a 4G module.
Rockchip RK3530 is not shown in the roadmap, but there’s a similar RK3566 processor, so I assume the company just changed the name.
Rockchip RK3566 specifications:
- CPU – Quad-core Arm Cortex-A55 @ 1.8GHz
- GPU – Arm Mali-G52 2EE
- NPU – 0.5 TOPS with support for INT8/ INT16
- 8M ISP 2.0 with 3F HDR(Line-based/Frame-based/DCG)
- Support MIPI-CSI2,4-lane
- 1080p60 H.265, H.264 encoding
- 4K H.264/H.265/VP9 60fps video decoder
- DVP interface with BT.656/BT.1120
- Memory – 32-bit DDR3L/LPDDR3/DDR4/LPDDR4/LPDDR4X
- Storage – eMMC 4.51, NAND Flash, SFC NOR flash, SATA 3.0, SD card via SDIO
- Support Dual Display
- MIPI-DSI/RGB interface
- HDMI 2.0
- Audio – 2x 8-ch I2S, 2x 2-ch I2S, PDM, TDM, SPDIF
- Networking – 2x RGMII interfaces (Gigabit Ethernet) with TSO (TCP segmentation offload ) network acceleration
- USB – USB 2.0 OTG and USB 2.0 host; USB3.0 HOST
- Other peripherals
- 3x SDIO 3.0 interface for Wi-Fi and SD card
- 6x I2C, 10x UART, 4x SPI, 8x PWM, 2xCAN interface
The processor targets Internet of Things applications and should be available in Q2 2020.
Rockchip RV1109 was unveiled last April, and we have some extra information about the processor:
- CPU – Dual-core Arm Cortex-A7 @ 1.0GHz
- NPU – 1.0TOPS with support for INT8/ INT16
- Memory – 32-bit DDR3/DDR3L/LPDDR2/LPDDR3/DDR4/LPDDR4
- Storage – eMMC 4.51, Serial NOR Flash with fast booting support, SD card via SDIO interface
- Display – MIPI-DSI/RGB interface up to 1080p @ 60 FPS
- Audio – 8-ch I2S with TDM/PCM, 2-ch I2S
- 13M ISP 2.0 with 3F HDR(Line-based/Frame-based/DCG)
- 2xMIPI CSI, LVDS, sub-LVDS
- 4K H.264/H.265 video encoder: 3840 x 2160 @ 30 fps + 720p @ 30 fps encoding
- 4K H.264/H.265 30fps video decoder
- 3840 x 2160 @ 30 fps encoding + 3840 x 2160 @ 30 fps decoding support
- DVP interface with BT.656/BT.1120
- Networking – RGMII interface with TSO network acceleration
- USB – USB 2.0 OTG and USB 2.0 host
- Other Peripherals
- Dual SDIO 3.0 interface for Wi-Fi and SD card
- I2C/UART/SPI interface
- Process/Package – 14nm FinFET, FCCSP 0.65
Rockchip RV1109 should already be available (launch in Q4 2019), and found in vision/AI applications such as IP cameras.
The new roadmap document does no provide much more info about RK3588, but the high-end processor from the company that was initially expected in Q1 2020 has apparently been delayed to Q3/Q4 2020.
Key features for RK3588:
- CPU – 4x Cortex-A76 and 4x Cortex-A55 cores in dynamIQ configuration
- GPU – Arm “Natt” GPU
- NPU 2.0 (Neural Processing Unit)
- Multimedia – 8K video decoding support, 4K encoding support
- Display – 4K video output, dual-display support
- Processor – 8nm LP
Natt is a goddess from Norse mythology, so it must be a new unannounced architecture for Arm Mali GPU. The last unknown Arm GPU architecture is Valhall found in Mali-G77 for example.
Rockchip processors also support wider temperature range from the usual consumer temperature range, to the extended “commercial grade” found in “K” variants such as RK3399K, and now there are some processors supporting automotive/industrial temperature range (-40 to 85°C) as well.
RK3358M/J processor was launched in 2019 for IoT and automotive applications and comes with four Arm Cortex-A35 cores, and an Arm Mali-G31MP2 GPU.
There are also a bunch of modules but I’m not convinced they are based on Rockchip IP, as for the 4G module at least, they probably went with either a Qualcomm, UNISOC or MediaTek solution.
Rockchip RM310 4G module supports download rate of up to 100 Mbps and upload rates of up 50 Mbps.
Rockchip RMSL201 3D structured light module should be designed for computer vision applications for face recognition, robotics, or virtual reality applications.
We highlighted some of the most interesting details in this post, but you may find more details in the roadmap (PDF).
