ARM Introduces Mali-470 GPU for Wearables, IoT and Embedded Applications

Mali-400 was announced in 2008, and since then has been used in various SoCs for smartphone, but now it’s mostly replaced by Mali-450 GPU in low cost mobile and STB SoCs, although Mali-400 is still being implemented in new SoCs such as Rockchip RK3128 processor. ARM has been working on a lower power version of the GPU, and just unveiled Mali-470 GPU targeting wearables, as well as embedded and IoT applications. Mali-470 GPU is said to use the same memory and AMBA interfaces as Mali-400, while keeping some of the improvements brought to Mali-450 GPU, and further lowering power consumption to just half of that Mali-400 in terms of mW per frames per second. Just like its predecessors, Mali-470 supports OpenGL ES 2.0, and like Mali-400 it will scale from 1 to 4 fragment processor, always combined with one single vertex processor. Mali-470MP1 is likely to be used in wearables […]

Rockchip RK6321 Dual Core Cortex A5 SoC Targets Wearables with WiFi, Bluetooth, 3G and GPS

Rockchip and Intel started to work on a platform called XMM6321 last year. It featured a dual Core Cortex A5 processor, 3G connectivity, WiFi, and GPS, which was aimed at entry level 3G smartphones and tablets. Fast forward to 2015, Rockchip showcased their RK6321 processor at the Hong Kong Electronics Fair, with very similar specifications compared to XMM6321, but instead it targets wearables such as smartwatches, or children and elderly tracker. So I’ m not quite sure whether Intel XMM6321 and Rockchip RK6321 are the same processor with a different name, or Rochchip tweaked RK6321 specifically for wearables. Key features of Rockchip RK6321 processor: CPU – Two Cortex A5 cores up to 1GHz with 32KB L1 D-cache, 32KB L1 I-cache, and 512KB L2 cache GPU – Supports OpenGL ES 2.0 Memory and Storage I/F – 16-bit LP-DDR2 SDRAM, 8-bit eMMC, 16-bit NAND Display I/F – MIPI DSI up to FWVGA […]

AMS AS7000 Biosensor is Designed for Strapless Optical Heart Rate Monitors

Heart rate monitors (HRM) with chest straps are now being replaced by more comfortable strapless HRM, such as UWatch UX. These products are enabled by photoelectric sensors that sample light modulated by blood vessels, which expand and contract as blood pulses through them. One of such solutions is the recently introduced AMS AS7000 including a Cortex M0 core, and a DSP implementing algorithm to process raw photoplethysmography (PPG) readings from the sensors to convert them into digital HRM and HRV (Heart Rate Variability) values. Highlights of AS7000 Biosensor: MCU – ARM Cortex M0 with 4KB RAM, 32 KB EEPROM I/Os – 9 GPIOs, UART, SPI, I2C Analog electrical and optical Frontends Hardware sequencer Synchronous detector Integrated LEd driver with current control Optical filters Supply Voltage – 2.6 – 3.6V Temperature Range –30 to 70°C Package – 18 pins AS7000 can deliver greater accuracy when it is paired with an external […]

Atmel Introduces SAMA5D2 Cortex A5 SoC with Extended Temperature Range, Lower Power Consumption

Today, the news broke out that Atmel will be bought by Dialog Semiconductor for about $4.6 billion. The Anglo-German company is little known as their main products are PMIC, audio and connectivity chips, but they’ve still managed to get the financing to purchase Atmel. But that’s not the purpose of the post today, and instead I’ll cover a new SAMA5 Cortex A5 SoC recently announced by the company, targeting industrial Internet of Things, wearables and point of sale applications. SAMA5D2 key features and benefits: ARM Cortex-A5 core running at 500MHz (785DMIPS). Floating point unit (FPU) for high-precision computing and accelerated data processing. 128KB of L2 cache for system performance Low power consumption Less than 150mW in active mode at 500MHz with all peripherals activated Less than 0.5mW in low power mode with SRAM and registers retention Sub 200µA in retention mode with context preserved New backup mode with DDR in […]

$55 UWatch UX Strapless Heart Rate Monitor Watch Syncs with iOS and Android Devices

Last time I checked about heart rate monitor, they required a chest strap to monitor ones heart rate, which I found cumbersome. It’s been while though, and I’ve now been informed that a low cost Bluetooth strapless heart rate monitor watch was available for $59.99 on GeekBuying. This type of product should provide a much more accurate evaluation of your daily calories burn rate than typical fitness bands based on an accelerometer and gyro sensor, but I’m not quite sure how they compare to the old models with a chest strap. Uwatch UX specifications and features: SoC – Mediatek Aster MT2501 ARM7 processor @ 108 MHz (A lower end version of MT2502 used in LinkIt One Devkit) System Memory – 32MB RAM Storage – 24MB NOR flash Heart rate monitor – Built-in photoelectric heart rate sensor Other sensors – magnetometer, 3-axis gravity and acceleration sensor Connectivity – Bluetooth 4.0 and […]
