ESP32 DevKitC V4 IoT development board ships with ESP32-WROOM-DA dual antenna module
The ESP32 DevKitC V4 is now selling with the ESP32-WROOM-DA module with two PCB antennas that was introduced last year in order to offer a longer WiFi range and better reliability. The development kit is exactly the same as the other ESP32 DevKitC V4 models, and the only difference is the dual antenna design. When running a recent version of the Arduino Core for the ESP32 (2.0.3 or greater), the ESP32 will automatically switch to the antenna with the strongest signal in order to deliver the best connectivity possible. ESP32 DevKitC V4 specifications: Wireless module – ESP32-WROOM-DA (PDF datasheet) with SoC – Espressif Systems ESP32-D0WD-V3 dual-core LX6 microprocessor with 520 KB SRAM, 2.4 GHz WiFi 4 and Bluetooth 4.1 connectivity Storage – 4MB SPI flash Two PCB antennas (ANT1 and ANT2) USB – 1x Micro USB port for power, programming, and debugging through USB-to-UART bridge up to 3 Mbps Expansion […]

3D game running on FPGA shown to be 50x more efficient than on x86 hardware
Sphery vs. shapes is an open-source 3D raytraced game written in C and translated into FPGA bitstream that runs 50 times more efficiently on FPGA hardware than on an AMD Ryzen processor. Verilog and VHDL languages typically used on FPGA are not well-suited to game development or other complex applications, so instead, Victor Suarez Rovere and Julian Kemmerer relied on Julian’s “PipelineC” C-like hardware description language (HDL) and Victor’s CflexHDL tool that include parser/generator and math types library in order to run the same code on PC with a standard compile, and on FPGA through a custom C to VHDL translator. More details about the game development and results are provided in a white paper. Some math functions were needed, including: floating point addition, subtraction, multiplication, division, reciprocals, square root, inverse square roots, vector dot products, vector normalization, etc. Fixed point counterparts were also used for performance reasons and to […]
AMD launches Ryzen Embedded V3000 Zen3 processors for storage and networking applications
AMD has just launched the Ryzen Embedded V3000 family of processors with four to eight Zen3 cores, a DDR5 memory interface, twenty PCIe Gen4 lanes, and two 10GbE interfaces that make it ideal for storage and networking applications, especially since there’s no GPU at all. The new embedded processors succeed the Ryzen Embedded V2000 Zen2 family introduced two years ago, and the Ryzen V1000 processors in 2018. For some reason, AMD decided to compare the new V3000 processors against the latter and claims up to 124% greater CPU performance, 50% improved memory transfer rate, twice the number of CPU cores, and improved I/O connectivity. There are five Ryzen Embedded V3000 SKUs at launch with the V3C48, V3C44, V3C18I, V3C16, and V3C14 whose key differences can be found in the table below. The AMD Ryzen Embedded V3C18I “industrial” processor also works in sub-zero temperatures for automotive and industrial applications. Shared specifications […]
Chromecast with Google TV (HD) features Amlogic S805X2 CPU with AV1 video support
Google has launched the new Chromecast with Google TV (HD) powered by an Amlogic S805X2 quad-core Cortex-A35 CPU that offers a cheaper alternative to the Chromecast with Google TV (4K) that is limited to 1080p60 resolution, instead of the 4Kp60 video output supported by the Amlogic S905X3 model. While the processor is slower, the system comes with less memory (1.5GB vs 2GB), and only supports 1080p60, it supports the more efficient AV1 video decoding and as well as A/B partitions for seamless updates since the firmware does not need to be downloaded to the internal storage before the Chromecast with Google TV (HD) specifications: SoC – Amlogic S805X2 quad-core Cortex-A35 processor with Mali-G31 MP2 GPU, 1080p60 H.265, H.264, VP9, AV1 video decoder System Memory – 1.5GB RAM Storage – 8GB eMMC flash with support for “virtual A/B updates with compression“ Video output – HDMI up to 1080p60 with HDR support […]
