Implementing Complex Motor Control Algorithms with a Standard ARM® Processor Core By Mike Copeland, Senior Staff Applications Engineer, Infineon Technologies
In the real-time MCU world, cost-effective complex motor control designs have been dominated by specialized cores. In many cases dual-core systems have been used, with the main core handling the control algorithm and a second “mini” core managing the real-time I/O and data manipulation.

Introducing the ARM®CortexTM-M0+ Processor: The Ultimate in Low Power By Joseph Yiu, Embedded Technology Specialist, ARM
The ARM®Cortex™-M0+ processor has just been announced. In this article we will introduce this new processor and explain how it can bring additional advantages to your embedded products. The Cortex-M0+ processor builds on the successful Cortex-M0 processor, which was released three years ago. The Cortex-M0 processor provided excellent code density and best in class energy efficiency in about the same silicon area as 8-bit and 16-bit processors. Since the release, the Cortex-M0 processor is the fastest ever licensed ARM processor core, passing 50 licensees by the end of 2011. Since then our design teams have continued to work hard and work with our Partners closely to see what can be improved. From that work the concept of the “Flycatcher” (project code name for Cortex-M0+) was formed. Download PDF Document

Two Heads are Better Than One: NXP's Dual-core LPC4300 DSP Controller Enhances a 7.1 Audio System By Gordon Cooper, Product Marketing Manager, Microcontroller Business Line, NXP Semiconductors
Designers can save time while creating efficient, DSP-enhanced audio systems by using NXP's dual-core LPC4300 series, the world's first microcontroller architecture to combine Cortex™-M4 and Cortex-M0 cores. This article looks at how a USB-based, multi-speaker system with 7.1 audio benefits from the dual-core format, by making good use of design partitioning and taking full advantage of on-chip peripherals.

Whoâs Ahead of the Rest in the High-end ARM® Module Market By Wolfgang Heinz-Fischer, Marketing Director/PR, TQ-Group
ARM generated a lot of favorable press by releasing the Cortexâ¢-A8 and Cortex-A9 processors. Thanks to the efficiency of the processors, which are now virtually on a par with low power architecture processors, while simultaneously displaying a significantly smaller chip area and much lower power consumption, the ARM®processors are suitable for a number of applications in which x86 processors previously held the monopoly. Hardly a day goes by without a new alternative to x86 solutions being presented. Apart from solutions for Mini ITX and all SBC formats, various Embedded Module solutions are now also in the race. It is no wonder that leading x86 module providers are once again setting the tone here, although the providers which once led the ARM module sector are also bringing out interesting module solutions.

A New Memory Test and Repair Solution for ARM® Processor Cores By Stephan Pateras, Product Marketing Director, Mentor Graphics
Many large systems-on-chip (SoC) designs today incorporate several third-party IP cores that cover a wide range of functionality. These cores often consist of high-performance embedded processors such as those available from ARM®. Highly optimized architectures and carefully tuned timing paths are required to achieve ever-increasing performance levels in these processors. Integrating design-for-test capabilities such as memory built-in self-test (BIST) and self-repair capabilities into these cores can affect performance levels because logic typically has to be inserted into functional paths.

How Can We Get Even Smarter about Smart Technology? By Marc Serughetti, Director of Product Marketing for Virtual Prototyping, Synopsys
mart phones are becoming very smart⦠but smart comes at a price. You need to understand your power consumption, integrate and test very large and diversified software stack, and also make sure that your hardware will support your software. For example, updates to firmware can and have reduced standby time by five times. Innocent looking RSS feeds can wake up the phone every ten minutes to pull internet data and cut standby time in half. But where there are problems, there is room for engineers to create solutions.

AMBA®4 ACEâ¢for Cache-Coherent big.LITTLE Multiprocessing By Ashley Stevens, Solutions Architect, ARM
The continual requirement for more processing performance while maintaining or improving energy consumption to increase battery life and/or reduce energy use, drives the requirement for power-efficient processing. It is well known that multiprocessing is a power-efficient way to add additional performance, rather than the converse of pushing a single processor to ever higher performance by increased use of low-Vt transistors, high-performance but leaky process technology and higher, over-drive power-supply voltages. Provided software can make use of parallel hardware itâs more power-efficient both in terms of power and area, to add additional parallel processor units. Symmetric Multiprocessing (SMP) is well known. Today most ARM®Cortexâ¢-A9 implementations are multicore, either dual or quad core. In the future, expect to see ARM processor-based SoCs with more than four cores. The move to the ARM Cortex-A15 increases the performance potential significantly, but at the cost of more transistors. Combined with the move to smaller geometry processes such as 32 or 28nm this results in increased leakage current during periods of low activity. Download PDF Document

Collaborative Verification of Third-Party IP in Early Adopter SoCs By Richard Pugh, Business Development Manager and Vijay Chobisa, Product Marketing Manager, Mentor
The presence of ARM®and other third-party IP in system-on-chip (SoC) designs has become ubiquitous, simplifying design while complicating verification. Both IP suppliers and SoC designers are hampered by unavoidable restrictions and impracticalities involved in sharing both proprietary code and large verification environments. Hence, there is a compelling need for a more effective way for IP end-users to share their test environments with IP vendors, without compromising the intellectual property of either party.
