ARM Unveils Ultra-efficient Cortex-A32 32-bit Processor Based on ARMv8 Architecture

So far you could safely equate 64-bit ARM processors with ARMv8 architecture. Not anymore. A few months after introducing Cortex A35 low power ARMv8 64-bit processor, ARM has now announced Cortex-A32 processor, even more power efficient, support ARMv8-A architecture, and designed for 32-bit embedded and IoT applications. Key features of Cortex-A32 cores: Architecture – ARMv8-A (AArch32) Multicore – 1-4x SMP within a single processor cluster, and multiple coherent SMP processor clusters through ARM AMBA 4 ACE, AXI 4 or AMBA 5 CHI technology ISA Support A32+T32 with full backward compatibility with ARMv7-A ARM TrustZone security technology ARM NEON Advanced SIMD DSP & SIMD extensions VFPv4 Floating point Hardware virtualization support Debug & Trace – ARM CoreSight DK-A32 So they’ve got rid of AArch64 instruction set out of ARMv8 architecture in order to improve power efficiency, while keeping the 100 new instructions part of Aarch32 to improve performance, and keeping ARMv7-A compatibility. ARM also claims the performance will be the same …

Toshiba Resistive Multi-touch Screen

Toshiba developed a proprietary algorithm for multi-touch resistive touchscreen and they exhibited a demo at Embedded World 2011. The hardware is based around Toshiba TMPA900 (ARM926EJ-S core running at 200 Mhz) and runs embedded Linux. This type of system is aimed at home appliances (washing machine, refrigerator…), industrial and medical applications and can be used with a pen, stylus or gloved hand. For example, a doctor wearing gloves would be able to use multi-touch gestures on such screens whereas it would not be possible on capacitive touchscreens or standard resistive touchscreens. It was not specified but I suppose that technology would only support 2 points since they only showed two fingers gesture in the demo. This should not be a problem for the type of application. An another advantage of this solutions is that it brings multi-touch technology to cost sensitive industrial applications. The technology is still under development and will be introduced to the market later this year. You …

Tablet Reference Design based on Samsung Exymos 4210

HardKernel, a Korean company, announced the ODROID-A, a tablet reference design based on Samsung Exymos 4210 (codename Orion), dual-core ARM Cortex-A9, Mali-400 GPU, 1GB Low Power DDR2, 10.1 inch 1366 x 768 TFT with capacitive multi-touch, Dual Camera, HSPA evolution, 9-axis sensor and running Android 2.3 Gingerbread. They will update it to Android 3.0 later on. This development kit will be available at the end of March 2011 for 749 USD (800,000 Won) for developers only. This should offer similar performance as the Motorola Xoom (except 3D maybe), and cost less which is a bit surprising for a development platform. They have an online community to support development on this hardware and they’ll provide the full source code and schematics free of charge. ODROID-A Specifications: Processor Samsung Exynos4210 Cortex-A9 Dualcore 1Ghz with 1MB L2 cache Memory 1024MB LP DDR2 800Mega data rate 3D Accelerator Mali-400 MP Core Micro-Sd slot 8GB bundle Display 10.1inch 1366 x 768 LVDS interface with capacitive …

Cypress Semiconductors PSoC Development Kits

Cypress Semiconductors was at Embedded World 2011 exhibiting their PSoC 5 development kits based on ARM Cortex M3 and analog & digital programmable modules. They had different development boards and demos based on PSoC 5: A simple board with PSoC 5, capacitive sensing, radio and accelerometer where they lit up a LED when the board moves  (CY8CKIT-014 kit – see below for details). A similar board with a dot-matrix LCD and a potentiometer, where they display the voltage at the Analog input on the LCD. (CY8KIT-010 kit – see below for details). A full development kit with PSoC 5, PSoC 3 and PSoc 5. (CY8KIT-001 kit – see below for details). Several demo of multi-touch and motion sensors capabilities etc.. The development kits are already available (engineering samples), but PSoC 5 will only be mass-produced in Q3 2011 since they are currently qualifying the chip. You can see the development kits and demos in the video below with the head …
