More Details about Rockchip RK3399Pro SoC, and RK1808 NPU

RK3399Pro Block Diagram

First announced in January 2018, Rockchip RK3399Pro was supposed to be a pin-to-pin compatible with Rockchip RK3399 processor, and adding a Neural-Network Processing Unit (NPU) capable of delivering 2.4 TOPS for acceleration A.I. workloads. Shortly after Pine64 announced they’d be offering Rockpro64-AI board in August, and later on Vamrs unveils ROCK960 PRO at a Linaro Connect event with an expected Q2 2018 launch. But none of the RK3399Pro boards are available, as there have been delays with RK3399Pro, and some commented an external NPU would be launched first with further details.   But today – courtesy of Vamrs – we have some more details about RK3399Pro features, a likely explanation for the delay, and some information about Rockchip RK1808 NPU chip. Contrary to the CES 2018 announcement, Rockchip RK3399Pro will come in a 27x27mm FCBGA1372 package instead of the 22x22mm FCBGA828 package for RK3399. So pin-to-pin compatibility is out of […]

Rockchip RK3308 & RK3326 Datasheets Released

Rockchip unveiled their first Arm Cortex-A35 processors with RK3326 “Gemini” and RK3308 SoCs last March. Both are designed for Smart AI solutions, and the company showcased two development kits for smart speakers and smart displays based on the new processors. We’ve already known the basic details for the processors for some times, with for example RK3326 featuring a Mali-G31 Dvalin GPU, but I’ve now been informed more details have surfaced since Rockchip published documentations including datasheets. Rockchip RK3308 Key features and specifications: CPU – Quad-core Arm Cortex-A35 64-bit Armv8-A CPU with NEON,  ARMv8 Cryptography Extensions, 256KB unified system L2 cache, and VFPv4  FPU, System Memory – 256KB internal SRAM, support for DDR2, DDR3/DDR3L, LPDDR2 external memory up to 512MB Storage Internal BootROM OTP – Support 4K bit Size, 3.5K bit for secure application External I/F – 8-bits Asynchronism Nand Flash, eMMC 5.1, SPI Nor/Nand Flash, SD Card all bootable; System […]

Acer Iconia One 10 is a 10.1″ Tablet Powered by Mediatek MT8167B Quad Core Cortex A35 Processor

So far, I had not seen that many devices based on Arm Cortex A35 64-bit cores which promise better performance than Cortex A7, while consuming 32% less than a Cortex A53. But Mediatek released MT8167B quad core Cortex A35 last year supporting 1080p30 video decoding, and HD+ (1280×800) displays. There’s also a Mediatek MT8167A SoC clocked at a higher 1.5 GHz, capable of handling higher resolution 1920×1200 displays, and 1080p60 videos. Acer Iconia One 10 tablet – also released last year – is powered by MT8167B SoC, and comes with 2GB RAM,  32GB storage, and a 10.1″ HD+ Display. Acer Iconia One 10 (B3-A40) specifications: SoC – MediaTek MT8167B quad core Cortex A35 processor @ 1.30 GHz with Imagination PowerVR GE8300 GPU System Memory – 2 GB DDR3L RAM Storage – 16 or 32GB storage, Micro SD Card slot up to 128 GB Display – 10.1″ IPS touch screen display; […]

Rockchip Unveils RK3308 & Gemini Cortex-A35 Processors for Smart Speakers

Rockchip has posted a tweet about smart speakers, specifically about Midea AI speaker based on Rockchip RK3229, but the second image is what caught my eyes, as it reveals two new Arm Cortex A35 processor designed for “Smart AI solutions”, namely RK3308 and “Gemini” Processor. Rockchip RK3308 “mainstream” processor specifications: CPU – Quad core Cortex A35 processor GPU – TBD (maybe none?) Audio Integrated 8-ch ADC and hardware VAD (Voice Activity Detection) module Multi-channel PDM/I2S/TDM audio interface Rockchip Gemini “high-end” processor specifications: CPU – Quad core Cortex A35 processor GPU – Mali Dvalin MP2 GPU Audio – “high-end smart audio solution”; multi-channel PDM/I2S/TDM audio interface Video I/O – LCD screen & camera support Rockchip will provide support for Android Thing and Linux for the processors, as well as integration with MIC arrays boards and popular voice services such as Amazon Alexa, Google Assistant,  Baidu DuerOS, and others. Arm Cortex A35 […]

Mediatek Helio X30 Deca-core SoC Features ARM Cortex-A73, Cortex A53, and Cortex A35 Processor Cores

Mediatek introduced Helio X20 last year with a tri-cluster architecture comprised of 2 powerful ARM Cortex A72 cores, 4 Cortex A53 cores, and 4 extra Cortex A53 cores operating at a lower frequency, and optimized for power consumption. But now that ARM has introduced ultra-low power Cortex A35 cores, and more powerful Cortex A73 cores,  the Taiwanese company has been able to improve its tri-cluster implementation for the upcoming Helio X30 deca-core processor with 2 Cortex A73 cores @ up to 2.8 GHz, 4 Cortex A53 cores @ up to 2.2 GHz, and 4 Cortex A35 cores @ up to 2.0 GHz. According to various sources on Weibo, the mobile processor also includes an Imagination PowerVR 7XT GPU, supports up to 8GB LPDDR4 RAM @ 1600 MHz (PoP – Package in Package), UFS 2.1 flash storage, up to 40MP camera sensors,  and its cellular modem will support LTE Cat.10 to […]

ARM Unveils Ultra-efficient Cortex-A32 32-bit Processor Based on ARMv8 Architecture

So far you could safely equate 64-bit ARM processors with ARMv8 architecture. Not anymore. A few months after introducing Cortex A35 low power ARMv8 64-bit processor, ARM has now announced Cortex-A32 processor, even more power efficient, support ARMv8-A architecture, and designed for 32-bit embedded and IoT applications. Key features of Cortex-A32 cores: Architecture – ARMv8-A (AArch32) Multicore – 1-4x SMP within a single processor cluster, and multiple coherent SMP processor clusters through ARM AMBA 4 ACE, AXI 4 or AMBA 5 CHI technology ISA Support A32+T32 with full backward compatibility with ARMv7-A ARM TrustZone security technology ARM NEON Advanced SIMD DSP & SIMD extensions VFPv4 Floating point Hardware virtualization support Debug & Trace – ARM CoreSight DK-A32 So they’ve got rid of AArch64 instruction set out of ARMv8 architecture in order to improve power efficiency, while keeping the 100 new instructions part of Aarch32 to improve performance, and keeping ARMv7-A […]
