Block Diagram of RZ-G2L

Renesas Electronics Corporation announced RZ/G2L MPUs, allowing enhanced processing for an extensive variety of AI applications. The RZ/G2L group of 64-bit MPUs includes three new MPU models featuring Arm Cortex-A55, and an optional Cortex-M33 core. These are RZ/G2L, RZ/G2LC, and RZ/G2UL MPUs. The Cortex-A55 CPU core typically delivers approximately 20 percent improved processing performance compared with the previous Cortex-A53 core, and according to Renesas, is around six times faster in “essential processing for AI applications”. The company already has four mid to high-end design level MPUs including RZ/G2E, RZ/G2N, RZ/G2M, and RZ/G2H, with combinations of Cortex-A53 and Cortex-A57 cores. The new RZ/G2L group of three MPUs forms the entry-level design with Cortex-A55. Hence, the seven MPU models together provide scalability from entry-level to high-end design.

Qt for MCUs – Qt Announces support for Microcontrollers

QT_TitleImage1

[Update August 24, 2019: Added information about expected release date and license] About Qt for MCUs Qt- The well known opensource toolkit for creating graphical interface announced their new release: Qt for MCUs, targeting MCU’s. The new graphical toolkit will be capable of running on devices without operating system. This may be a game changer in the entire MCU world, since Qt for MCUs allows developers to create fluid user interfaces on cost-effective micro controllers. This means we will be able to see smartphone like GUI’s which are running on low-end  MCU’s with limited resources. With reference to their press release, assuring that Qt-GUI will consume less power to save the battery life. Qt for MCUs Software Stack While developing any applications for MCU,  developers still can use their powerful declarative UI language QML and rich set of ready-made Qt Quick controls.  And the C++ APIs, helps the user interface […]

Renesas R-Car M3 Starter Kit is Designed for ADAS Applications

Most boards targeting the automotive market are impossible to purchase by individual, so last year I was pleasantly surprised when I discovered Renesas R-Car M2 Porter Linux automotive infotainment development board was available for sale on Digikey, and had good documentation on eLinux.org. The company has now introduced another automotive board, namely R-Car V3M starter kit, that’s not designed for infotainment, but instead for ADAS (Advanced Driver Assistance Systems) or even AD (Automated Driving) applications. Specifically, the board is supposed to “accelerate the development of New Car Assessment program (NCAP), front camera applications, surround view systems, and lidars” leveraging the company’s R-Car V3M image recognition SoC. Renesas R-Car V3M starter kit (V3MSK) specifications: SoC – Renesas R-Car V3M processor with two Cortex A53 64-bit cores @ up to 800 MHz, a dual lockstep Cortex-R7 32-bit core @ up to 800 MHz, IMP-X5-V3M image recognition engine System Memory – 448KB RAM on-chip; […]

Octo SPI / HyperBus Interface is Designed for High Speed Serial Flash, RAM, and MCP

So far, if you needed high speed storage with low pin count in your MCU based board, you could use QSPI (Quad SPI) NOR flash, but earlier this month I wrote about STM32L4+ MCU family, which added two Octo SPI interfaces. I had never heard about Octo SPI previously. Those two interfaces can be used with single, dual, quad, or octal SPI compatible serial flash or RAM, and  support a frequency of up to 86 MHz for Octal SPI memories in STM32L4+ MCU. STMicro OctoSPI interface also supports Cypress/Spansion Hyperbus mode to connect to HyperFlash or HyperRAM chip, or even HyperFlash + HyperRAM Multi-Chip packages (MCP), and variable or fixed external memory latency as defined by the Hyperbus protocol specification. The latter reveals Hyperbus supports performance up to 400 MB/s (provided the controller support 200 MHz), and relies on either 11 bus signals using 3.0V I/O (Single-ended clock CK), or […]
