ARIES M100PF PolarFire FPGA System-on-Module Targets Industrial Applications, RISC-V Development


MicroSemi unveiled PolarFire RISC-V FPGA SoC at the end of last year, bringing an alternative to Xilinx Zynq (Arm Cortex-A9 + FPGA) and UltraScale+ (Cortex A53 + FPGA) SoCs. The system-on-chip is expected to be mass produced later in 2019, so development is done on HiFive Unleashed RISC-V board and its FPGA expansion board. In the meantime, MicroSemi PolarFire FPGAs (without RISC-V hard core) are available now, and ARIES Embedded planning to showcase what they claim is the first PolarFire FPGA system-on-module at Embedded World 2019 with their M100PF SoM targeting industrial applications. ARIES Embedded M100PF key features and specifications: A choice of 3 PolarFire FPGAs MPF100T – 109KLE, 336 Math Blocks (18x18MACC) MPF200T – 192KLE, 588 Math Blocks (18x18MACC) MPF300T – 300KLE, 924 Math Blocks (18x18MACC) System Memory – 512 MiB / 1 GiB / 2 GiB DDR3 RAM Storage – 256 MiB configuration device, 4 GiB eMMC flash by default (Option up to 64GB) 2x Samtec QSH-090-01-F-D-A 180-pin …

MicroSemi Introduces PolarFire FPGA & RISC-V SoC

Polaris FPGA + RISC-V SoC

In the past we’ve covered SoCs comprised of Arm cores and FPGA fabric via Xilinx Zynq-7000 series SoCs and Zynq UltraScale+ series MPSoCs, respectively featuring up to two Arm Cortex A9 cores, and up to four Cortex A53 cores. MicroSemi has now announced an alternative, not based on Arm cores, but instead based on SiFive U54-MC RISC-V cores combined with PolarFire FPGA fabric. PolarFire FPGA RISC-V SoC key features & specifications: FPGA – Microsemi PolarFire FPGA Processor Cores – Up to 4x SiFive U54-MC RISC-V cores clocked at up to 1.5GHz (performance similar to Cortex-A35 cores); 28nm process Deterministic Coherent Multi-core CPU Cluster Deterministic L2 Memory Subsystem System Memory I/F –  Integrated DDR4/LPDDR4 Controller and PHY Storage – Secure Boot, 128K Boot Flash Debug capability Rich I/Os Low Power – Low static power; power optimized transceivers, up to 50% lower power compared to SRAM based FPGAs So we don’t have the full picture just yet, and we’ll have to wait …

Particle Unveils Mesh SoMs and IoT Developer Tools

Earlier this year, Particle unveiled three IoT development boards based on nRF52840 Bluetooth 5/802.15.4 WiSoC and supporting Particle Mesh, which interestingly is not based on Bluetooth Mesh or even Bluetooth, and instead relies on Thread specification/OpenThread implementation, and the 802.15.4 radio of the chip with Bluetooth only used for the initial setup stage. Particle announced the shipping date (October 2018 or… this month) for their Mesh boards pre-ordered in February, as well as three new products in a recent blog post. One of the products is a family of system-on-modules compatible with Particle Mesh, while the other two are related IoT developer tools. Particle Mesh SOMs The Particle Mesh SOMs will have similar names and features as corresponding Particle mesh developers kits such as Boron (NB-IoT / eMTC + BLE + Mesh) and Argon (ESP32 WiFi, BLE + Mesh), but with an edge connector and designed as enterprise-grade, production-scale version of the dev boards. The modules are still in development, …

A First Look at ESP32-LyraTD-MSC Audio Mic HDK with Baidu DuerOS Assistant

Earlier this year, Espressif Systems had unveiled their ESP32-LyraTD-MSC Audio MiC HDK (Hardware Development Kit) which features an ESP32-WROOM module, a 4-mic array DSP, 3 microphones, an audio jack, and various I/Os. I received the board a couple of weeks ago, and while there’s no public information released yet, the company provided me with ESP32-LyraTD-MSC User Guide in English. Eventually, I’d expect Google Assistant and Amazon Alexa to be supported, but in the meantime I had to leverage my (lowly) Chinese language skills to get started since the kit is pre-loaded with firmware connecting to Baidu DuerOS voice assistant. ESP32-LyraTD-MSC Unboxing The kit came in a bland Espressif Systems carton box. Inside the package, I could only find one kit comprised of two boards. The bottom board read ESP32_MicrosemiDSP_Mainboard-V1, and does not show much apart from marking for connectors, headers and the power switch. While the top comes with eight buttons (Vol +, Vol -, Mode, Boot, RST, Rec, Play, …

MicroSemi ZL38063 Audio Processor is Designed for Microphone Arrays

I’ve already been experimenting with DIY smart speakers and corresponding services for example using ReSpeaker board with Microsoft Bing Speech API, or Orange Pi Zero with Google Assistant SDK. But so far all the hardware platforms I used only came with one microphone, no microphone array that help with wake word detection in noisy environments. Last week-end, I received Espressif Audio Mic HDK, an ESP32 board with a 3-microphone array which I’ll review a in a few weeks once documentation becomes available and I clear some other items in my review list. In the meantime, I checked out the hardware, and found out the mainboard also comes with Microsemi ZL38063 audio processor specifically designed for microphone array. The chip was released las year, and can be already found in the company’s AcuEdge Development Kit for Amazon AVS, but since I’m going to use a board based on ZL38063 I’d thought to have a closer look to better understand its capabilities. …
