Minnow Server is a Secure Web Server for Microcontrollers

Minnow Server Secure Websocket

Many embedded systems have a limited amount of memory, which would normally run programs with smaller footprints than on desktops or servers. For example, nginx and Apache2 are the common web servers, but on hardware with limited memory, smaller footprint web servers may be required, so that’s why I wrote a list of web servers for embedded systems running Linux/uClinux many years ago. But now, even platforms based on microcontrollers often need to run web server usually for configuration. We’ve already shown how to use Arduino to serve a simple web page and did the same in Getting Started with NodeMCU Board Powered by ESP8266 WiSoC but using Lua programming language instead. It may be more convenient to run a proper web server however, as it’s easier to change the interface, and we previously covered MicroWebSrv lightweight web server that works on platforms running MicroPython such as Pycom boards. Real Time Logic offers another open source alternative with their Minnow Server …

AMBE+2 Vocoder Promises High Voice Quality at Low (2.0 to 9.6 Kbps) Data Rates

Opus 1.2 open source audio codec was release a few months ago with the ability to deliver low power low high-quality audio bitrate for speech with bitrates as low as  12 Kbps. Digital Voice Systems (DVSI) claims to have gone even lower thanks to their AMBE+2 vocoder (Advanced MultiBand Excitation) providing high-quality speech at data rates from 2.0 to 9.6 kilobytes per second. AMBE+2 vocoder is said to outperform the company’s previous generation AMBE+ Vocoder as well as the G.729 and G.726 vocoders, while operating at only 4.0 Kbps. The vocoder is suitable for mobile radio, secure voice, satellite communication, computer telephony, digital voice and storage applications The solution can be integrated into product either using software licensing, or through Vocoder chips, and the company lists the following key benefits: Maintains speech intelligibility and speaker recognition at rates as low as 2.0 kbps Resistant to background noise and channel bit errors Customizable data from 2.0 to 9.6 kbps Uses fewer computations …

Vortex86DX3 is a New x86 SoC for Embedded Systems

Intel is already making embedded version of their processor with example with Bay Trail-I or Quark SoCs, but Taiwan based DMP Electronics has also been making x86 SoC such as Vortex86EX that can be found in $39 86duino Zero board, which must be one the cheapest, if not the cheapest, x86 board on the market. Of course, this is not designed to run Windows and Office, but rather some embedded (IoT) applications. The company has recently launched Vortex86DX3, a more powerful x86 dual core processor, suited to embedded systems and communication products such as thin clients, NAT routers, gateways, etc… DMP Vortex86DX3 specifications: Dual Core x86 Processor @ 1GHz with 6 stage pipeline, x86 instruction set Floating point – Implements ANSI/IEEE standard 754-1985 for binary Floating-Point Architecture Cache – 8-way 32K I-Cache, 8-way 32K D-Cache,  4-way 512KB L2 Cache with write through or write back policy System DDR3 Control Interface – 32-bit data bus; DDR3 size support up to 2GB (Block diagram says …

Alpha Data ADM-XRC-7Z1 XMC Mezzanine Card Powered by Xilinx Zynq SoC

Alpha Data, a company providing solutions for compute intensive applications, has announced the ADM-XRC-7Z1, an XMC board powered by Xilinx Zynq-7045 or Zynq-7100 Cortex A9 + FPGA SoC targeting application such as software-defined radio, radar and sonar processing, image processing and machine vision. If you are like me, and have never heard about XMC mezzanine cards before, here’s what Wikipedia has to say about it: XMC, or Switched Mezzanine Card, is a PCI Mezzazine Card (PMC) with high-speed serial fabric interconnect defined by the VITA 42 standard. XMC specifies a 5th connector (“P15”) that supports PCI Express (VITA 42.3) or other high speed serial formats such as Serial RapidIO (VITA 42.2) and Parallel RapidIO (VITA 42.1). VITA (VMEbus International Trade Association) is an organization developing and promoting open technology standards that you can download for a fee. Here are the specifications of the board: SoC – Xilinx Zynq-7045 or Zynq-7100 dual Cortex A9 + FPGA SoC System memory: 1 bank of …
