PULPino Open Source RISC-V MCU is Designed for IoT and Wearables

lowRISC is not the only open source processor project based on RISC-V instructions, as researchers at ETH Zurich university and the University of Bologna have developed PULPino open-source processor based on RISC-V instructions set, optimized for low power consumption, and targeting wearables and the IoT applications. PULPino is a single core processor derived from the PULP project (Parallel Ultra-Low-Power Platform) featuring a quad core RISC-V SoC with new RI5CY Signal Processing ISA extensions designed by the universities. The core has an IPC (instructions per cycle) close to 1, full support for the base integer instruction set (RV32I), compressed instructions (RV32C) and partial support for the multiplication instruction set extension (RV32M). PULPino also features peripherals such as I2S, I2C, SPI and UART. PULPino has already been taped out as an ASIC in UMC 65nm at the beginning of the year, but the RTL code be run on Xilinx Zynq-7010 powered Zedboard, […]

OpenAMP Open Source Framework Provides the Glue between Linux, RTOS, and Bare Metal Apps in Heterogeneous SoCs

SoCs becoming more complex, and go beyond homogeneous multicore systems by mixing different type of cores such as high performance cores, low power real-time cores, or even FPGA fabric. Examples include NXP i.MX6 SoloX with an ARM Cortex A9 core for Linux apps, and an ARM Cortex M4 core for real-time tasks, or Xilinx Zynq UltraScale+ MPSoC with Cortex A53 core for higher level apps, Cortex R5 cores for real-time processing, and Ultrascale FPGA logic. All these different cores are running their own Linux based OS, real-time operating system or bare metal application, and all this makes software development an even greater difficult tasks. In order to reduce the complexity, and address some of the issues, the Multicore Association has launched a new working group targeting the management, expansion, and standardization of OpenAMP (Open Asymmetric Multi Processing), an open source framework that allows operating systems to interact within a broad […]

GoWarrior Tiger Development Board with ALi M3733 SoC To Support Android, Debian and FreeRTOS

There was a time when development boards were really hard to get for individuals with companies not wanting to waste their time with hobbyists, but the maker revolution changed all that, and now many companies want to get involved in “open source” board for the developer’s community. The latest board trying to emulate the Raspberry Pi is GoWarrior Tiger powered by ALi M3733 dual core cortex A9 processor with 1GB RAM, 4GB Flash, Ethernet and WiFi, HDMI and AV output, and two 40-pin expansion headers. Tiger board specifications: SoC – ALi M3733-AFAAA dual Cortex A9 processor @ 1.0 GHz with ARM Mali-400 MP2 GPU System Memory – 1GB DDR3; dual channel 1600 MT/s, 800MHz Storage – 4GB on-board NAND Flash + micro SD slot Video & Audio Output – HDMI 1.4 port up to 1080p, with support for HDCP and CEC, 3.5 mm AV jack Connectivity – 10/100M Ethernet, 802.11 […]
