SiFive Performance P650 RISC-V core to outperform Arm Cortex-A77 performance per mm2

SiFive Performance P650

About six months have passed since the SiFive announcement of the Performance P550 “fastest 64-bit RISC-V processor” ever, and the company has now introduced an even faster RISC-V core with the Performance P650 that’s expected to match Cortex-A77 performance. Building upon the Performance P550 design, the SiFive Performance P650 is scalable to sixteen cores using a coherent multicore complex, and delivers a 40% performance increase per clock cycle based on SiFive engineering estimated performance in SPECInt2006/GHz, thanks to an expansion of the processor’s instruction-issue width. The company compares P650 to the Arm family by saying it “maintains a significant performance-per-area advantage compared to the Arm Cortex-A77”. SiFive Performance P650 key features: 64-bit RISC-V (RV64GCB) core Sv39/Sv48 Virtual Memory Support Multi-core, multi-cluster processor configurations with up to 16 cores Performance > 11 SpecINT2006/GHz Thirteen stage, four-issue, out-of-order pipeline tuned for scalable performance Private L2 Caches and Streaming Prefetcher for improved memory […]

Tribulations with Linux on Zidoo M6 Rockchip RK3566 mini PC

Rockchip Short eMMC D0 pin

After our review of the Zidoo M6 mini PC with Android 11, we’ve installed Linux on the Rockchip device, and we did boot to a Linux Qt user interface built with buildroot. Let’s try to see what we can do with the image, and then try Ubuntu from a competing mini PC to check out if that can work. Since there’s no package manager to install a screenshooting program, I tried to use the usual method to take a framebuffer screenshot.

It generated an 8MB file which looked good, but the content was just comprised of zeros.

I asked Zidoo for a method to take screenshots in their Linux image, but I was told there weren’t any at this time… No worries, let’s try some of the applications in the Qt interface starting with the Multivideoplayer: It starts well with 9 videos of Big Buck Bunny playing simultaneously, […]

Seeed XIAO BLE – A tiny nRF52840 Bluetooth 5.0 board with (optional) IMU sensor and microphone

Seeed XIAO BLE Sense

Seeed Studio has just introduced two new members to their XIAO board family with the Seeed XIAO BLE and XIAO BLE Sense boards equipped with Nordic Semi nRF52840 Bluetooth 5.0 microcontroller, as well as an IMU sensor and microphone on the “Sense” model. Just like the earlier XIAO RP2040 board, the tiny Seed XIAO BLE board can be programmed with Arduino, MicroPython, and CircuityPython, and offers two headers with 7-pin each for GPIOs. What’s really new is the wireless connectivity, the sensors, and a battery charging circuitry. Seeed XIAO BLE specifications: Wireless MCU –  Nordic nRF52840 Arm Cortex-M4F microcontroller @ up to 64 MHz with  1 MB flash, 256 KB SRAM, Bluetooth 5.0, NFC, Zigbee connectivity Storage – 2 MB QSPI flash Expansion I/Os 2x 7-pin headers with 1x UART, 1x I2C, 1x SPI, 1x NFC, 1x SWD, 11x GPIO (PWM), 6x ADC 3.3V I/O voltage (not 5V tolerant) Sensors […]

Android 12 for TV released for ADT-3 Developer Kit

Android 12 for TV

While Android 12 images and related AOSP source code were released in October, it took a bit longer for Android 12 for TV. But the latest version of Android for larger screens has apparently been released yesterday on the developer website with Android 12 for TV now available, albeit only for the ADT-3 Developer Kit based on the Amlogic S905Y2 processor. Google says they’ve improved the user experience and compatibility on TV devices with media playback improvements, a refined user interface, enhanced privacy and security, as well as better support for HDMI and TV tuners. Highlights of the Android 12 for TV release include: User Interface Background blurs using RenderEffect and in WindowManager 4K UI support (CNXSoft: up to now most devices were using a 1920×1080 user interface (framebuffer), and play 4K video on another hardware video buffer) Accessibility settings for font sizes Media improvements Automatic refresh rate switching to […]

Rockchip RK3588 benchmarks show up on Geekbench

Rockchip RK3588 benchmarks

We’ve been talking about the Rockchip RK3588 Cortex-A76/A55 processor since it showed up in a roadmap in the Spring of 2019, and the initial plan was for a release in Q1 2020. But as most regular readers know, there have been delays after delays, and some people have even started to associate RK3588 with vaporware. But there may be light out of the tunnel with what appears to be a Rockchip RK3588 platform showing up on Geekbench website. It’s a system running Android 12 with 8GB of RAM, and the base frequency of the octa-core processor is shown to be only 1.8 GHz. We cannot draw too many conclusions about the score at this time. I would have expected a higher frequency for the Cortex-A76 cores, but maybe this is only temporary, or GeekBench only detects the frequency of the “LITTLE” Cortex-A55 cores, which appears to be the case for […]
