ARM Cortex-A35

Posted by Charbax – November 13, 2015

ARM announces that 50% of the Smartphones sold in 2015 are 64bit already. This is a phenomenal success for ARM's 64bit deployment. At ARM TechCon 2015, ARM announces ARM Cortex-A35, an upgrade for ARM Cortex-A7 which is currently the most popular ARM Cortex-A core shipping in most of the current low-end to mid-range Smartphones, at 10% lower power consumption, ARM Cortex-A35 brings up to 40% higher performance compared to ARM Cortex-A7! This will bring 64bit to even more Smartphones for the entry-level to mid-range markets starting before the end of 2016. ARM Mali-470 is a good power efficient GPU to use with ARM Cortex-A35, and it can be used in big.LITTLE configurations together with ARM Cortex-A72, ARM Cortex-A57 or ARM Cortex-A53.

ARM IoT Security Strategy in ARMv8-M

Posted by Charbax – November 12, 2015

Milosch Meriac, ARM IoT Security Engineer, talks about the strategy ARM is working on to make Internet of Things secure. ARM is convinced that many IoT security problems can be solved with standardised building blocks. ARM is developing the uVisor, a self-contained software hypervisor that creates independent secure domains on ARM Cortex-M3 and M4 microcontrollers (M0+ will follow). Its function is to increase resilience against malware and to protect secrets from leaking even among different modules of the same application. The uVisor is one of these basic building blocks – complementary to other important blocks like robust communication stacks, safe firmware updates and secure crypto libraries. The design philosophy of uVisor is to provide hardware-enforced compartments (sandboxes) for individual code blocks by limiting access to memories and peripherals using the existing hardware security features of the Cortex-M microcontrollers. Breaking the established flat security model of microcontrollers into compartmentalised building blocks results in high security levels, as the reach of flaws or external attacks can be limited to less sensitive function blocks. A basic example of uVisor is preventing unauthorised access to flash memory from faulty or compromised code. This not only prevents malware from getting resident on the device, but also enables protection of device secrets like cryptographic keys. Services built on top of ARM's security layer can safely depend on an unclonable trusted identity, secure access to internet services and benefit from encryption key protection.

Keynote: ARM Cortex-A35, ARMv8-M, Cryptocell, mbed connector announced by ARM CTO Mike Muller

Posted by Charbax – November 11, 2015

ARM CTO Mike Muller announces ARM Cortex-A35 to power the future of Low to Mid-range Smartphones and is also good for Wearables and Embedded, 20% higher performance and 10% lower power consumption compared to ARM Cortex-A7. ARMv8-M which is the next generation architecture for ARM Cortex-M microcontroller devices shipping into Billions of devices per year. Mike Muller talks about ARM's big work on security for IoT and to connect IoT with the Cloud, ARM launches the mbed connector service and shows mbed OS 3.0.

ARM Cordio Radio IP and ARM Subsystem for IoT

Posted by Charbax – June 2, 2015

At Computex 2015, ARM launches their new ARM Cordio Radio IP ultra low power Bluetooth LE 4.2. It has an analog RF component, a digital baseband modem component and mbed IoT subsystem running on an ARM Cortex-M3, based around the mbed OS and mbed device server allowing to build a solution around IoT devices and to connect them to the web. The ARM mbed OS runs on ARM Cortex-M devices. ARM is partnering with TSMC using their 55ULP process to dramatically lower the power consumption getting a 40% reduction in dynamic power consumption and a 25% reduction in the leakage.

ARM Instruction Set design history with Sophie Wilson (Part 3)

Posted by Charbax – May 10, 2015

The first ARM processor was designed in 1983-1985 to get more performance in Acorn Computers to enable low cost performance computing for the masses, these choices in the ARM design that Sophie Wilson made back then define most of the ARM processors on the market today.

The first ARM processor in the world with Sophie Wilson (Part 2)

Posted by Charbax – May 10, 2015

In 1986, Acorn shipped the ARM Development System, the world's first ARM development board to ever be sold with an ARM Processor in it, a Tube-linked second processor for the BBC Master which allowed developers to write programs for ARM! Sophie Wilson, original ARM designer at Acorn Computers, talks about the History of ARM, with the devices that used ARM1, ARM2, ARM3, ARM610 in the Apple Newton and talking about how ARM was spun out of Acorn, how the ARM business model made ARM such a huge worldwide success.
