Allwinner A-Series Processors 2020-2021 Roadmap – Allwinner A33E, A100 and A200 SoCs

We previously discussed Allwinner business units where each can share the same silicon (with different a name) but maintains its own software stacks for different target applications. Allwinner A-Series is the most well-known as Allwinner A10 & A20 were very popular SoC for tablets and TV boxes many years ago. CNX Software received two slides that originated from Allwinner this morning. The first one shows the different Allwinner processor families, and the second provides a roadmap for A-Series processors for tablets with A33E, A100, and A200 coming this year and next. Let’s go through the Allwinner processor families first and their main use case: R-Series and MR-Series – Smart home applications A-Series – Tablets VR-Series – Virtual reality H-Series and F-Series- High-performance applications like multimedia (TV boxes) T-Series- Automotive, I suppose mostly infotainment V-Series – Camera SoCs XR/XIN-Series – Wireless chips like the infamous XR819 WiFi chip. AXP – PMIC (Power Management IC) accompanying the company’s Arm SoCs The second …

Allwinner R329 Smart Speaker Processor Features Arm China’s AIPU (Artificial Intelligence Processing Unit)

Allwinner R329

Allwinner R328 is a dual-core Cortex-A7 processor with 64MB or 128MB built-in RAM designed for low-cost smart speakers that was introduced last year and found into smart speaker sold in mainland China. According to a recent press release (in Chinese only), the company has now released a 64-bit update with Allwinner R329 dual-core Cortex-A53 processor equipped with dual HIFI4 DSP for audio post-processing and pre-processing, as well as Arm China’s AIPU (Artificial Intelligence Processing Unit) delivering up to 0.256 TOPS at very low power. There’s no product page for Allwinner R329 yet, so I extracted some specifications from the press release: CPU – Dual-core Cortex-A53 @ up to 1.5 GHz DSP- Dual-core HIFI4 DSP @ 400 MHz AI Accelerator – Arm China AIPU with 0.256 TOPS Built-in DDR RAM Audio Embedded second-generation VAD hardware 5x audio ADCs 2x audio DACs with 100dB SNR I2S and DMIC controller 5-1-channel and 7.1 channel support Integrated dual LDO The company will also provide …

Allwinner H616 TV Box Processor Comes with Mali G31 GPU, Supports Android 10

Allwinner H616

Allwinner H6 quad-core Cortex-A53 processor with Arm Mali-T720 GPU was launched in 2017 and made its way into various TV boxes and SBC’s. But last year, we got some news of lower-cost versions of the processor with Allwinner H603 and H6 VC200-OS SoC’s. Allwinner H616 Processor Advantages So the first time, I read about Allwinner H616, I thought it was yet another variant of little interest. But it turns out H616 is the first processor from the company with a Bitfrost GPU, namely Mali G31MP2, meaning it supports Vulkan, and down the line, it could potentially be supported by Panfrost open-source graphics driver. Another positive for the processor is support for Android 10, while AFAIK other H6 processors are stuck to Android 9.0. Another advantage is low power consumption leading to lower CPU temperature. It might be a process change or some other optimizations in the silicon, we just don’t know at this stage. The illustration also claims a lower …

Allwinner H6 VC200-OS Processor is a Cheaper Version Allwinner H6 SoC without PCIe, GbE, Camera…

Allwinner H6 CV200-OS

Allwinner H6 SoC has been around a few years, first used exclusively in Zidoo H6 Pro TV box, but then finding its way into other TV boxes, and some single board computers such as Orange Pi 3 or Pine H64 model B. There’s no a cost-down version called Allwinner H6 VC200-OS with most of the same features but without the mostly useless PCIe port (since it does not work well on H6), and other interfaces. I’ve gone through Allwinner H6 (V200) specifications and highlighted the ones missing or updated in H6 VC200-OS using stricken bold or bold text using information from the datasheet. CPU –  Quad-core ARM Cortex A53 with NEON, hardware Java acceleration, and FPU 3D GPU – Dual shader ARM Mali-T720 with support for OpenGL ES3.1/3.0/2.0/1.1, OpenCL 1.1/RenderScript, Microsoft DirectX 11 FL9_3 Memory I/F – DDR4/DDR3/DDR3L/LPDDR2/LPDDR3 interfaces Storage I/F – 1x eMMC 5.1 flash interface, 1x NAND Flash interface for SLC/MLC/TLC flash memory with up to 80-bit error-correcting …

Allwinner R328 Smart Speaker & System-on-Module Spotted in China

Allwinner R328 Smart Speaker

Earlier this year, Allwinner introduced some AIoT (AI + IoT) processors including Allwinner R328 dual-core Cortex-A7 processor for “low-cost voice interaction solutions” aka low-cost smart speakers. I did not pay too much attention at the processor at the time, but since then, the company has released a product brief with some more details about the processor. We can see it integrates 64MB to 128MB DDR3 memory which should be enough to run Linux without external memory, and truly provide a low-cost solution for smart speakers, and I was told the chip may cost around $3. I was also asked whether Allwinner R328 smart speakers were already shipping. A Google search in English did not help, so I had to switch to Chinese, and after visiting several sites, I could see some Allwinner A328 platforms including a smart speaker and a system-on-module were showcased at some event in China. We’ve got a photo, but that much more info about the speaker …

Allwinner V316 Processor is made for Low-Cost “True” 4K 30 FPS Cameras

Allwinner V316 4K Camera Board

Allwinner V-Series processors target camera applications, especially sports and action cameras, and we’ve already coverd Allwinner V3 single core Arm Cortex-A7 processor for 1080p60 / 4K15 cameras, as well as Allwinner V5 quad core Cortex-A7 processor for 4K30 cameras enhanced with artificial intelligence capabilities. Allwinner has showcased and/or unveiled more Cortex-A7 processors at CES Asia 2019 such as Allwinner R328 for voice applications, or Allwinner T7 for automotive dashboards, as well as a new camera processor called Allwinner V316 with two Arm Cortex-A7 cores, apparently the same 4K @ 30 fps H.265/H.264 encoder as in V5, but without AI engine architecture. Allwinner V316 key features and preliminary specifications: CPU – Dual core Arm Cortex-A7 processor @ 1.2 GHz ISP – HawkView 6.0 image processor with 2D/3D intelligent noise reduction, frame width dynamic synthesis, sharpening enhancement, specific color enhancement and other image pre-processing techniques Video – 4K Smart H.264/H.265 video encoder with built-in hardware distortion correction and electronic anti-share; 720p @ …

How One Line of Code Tripled Allwinner A20 SATA Write Performance

Allwinner A20 SATA Performance Patch

If you’ve been following this blog long enough, you may remember that all linux-sunxi community work aiming at improving u-boot and Linux software support on Allwinner processors started with Allwinner A10 processor found in MeLE A1000 TV box back in 2012, which at the time provided an interesting alternative to Raspberry Pi board that was in short supply at launch time and several months after. One of the most interesting feature found in Allwinner A10 single core Arm Cortex-A8 processor was its SATA interface, and Allwinner A20 was announced a few months later with a dual core Cortex-A7 processor and virtually the same peripherals as Allwinner A10, including SATA. However when I  tested CubieTruck board connected to a mechanical drive, I noticed sequential SATA performance was fine for reads (~180MB/s), but writes were fairly slow at around 36 MB/s. Other people complained about it, and some looked into it, and at one point it appeared the maximum SATA write performance …

Allwinner Tablet SoC Roadmap 2019 – 2020

Allwinner A-Series Roadmap 2019 2020

Both Rockchip and Amlogic have some pretty interesting processors coming down the pipe with for example Rockchip RK3588 Cortex A76/A55 or Amlogic S922D Cortex A73/A53 SoCs both featuring an neural processing unit (NPU) for AI workloads acceleration at low power. The companies also have updated entry-level quad Arm Cortex-A55 processors with RK3530 and S905X3 models which are planned to launch later this year. But this made me wonder what was going with Allwinner since the company got really quiet, except for the “launch” of renamed processors for a specific business unit. That’s the only company among the three to have yet to announce a Cortex-A7X 64-bit Arm processor. The good news is that the company has released a roadmap of sort for their A-Series processors for tablets. The less good news is that very few details are available for the processors except for one: Allwinner A50 – Quad core Cortex-A7 processor @ 1.8 GHz with Mali-400MP2 GPU, GMS certification. Suitable …
