Debug for Cortex-M gains power: probe gives full instruction trace in real time I-jet Trace from IAR Systems is a probe providing extensive debugging and trace functionality, delivering large trace memory capacities and high-speed communication via USB 3. The probe supports all ARM Cortex-M cores, including the ARM Cortex-M7 core, that have Embedded Trace Macrocell (ETM) capabilities. Tracing every single executed instruction, ETM provides developers with unmatched insight into the microcontroller’s activities and enables them to find critical bugs that are difficult or even impossible to find any other way. I-jet Trace has a memory capacity of 32 Msamples and is designed to take full advantage of the speed and current delivery of the SuperSpeed USB 3 communication port, enabling high-speed debugging. The probe allows real-time trace clocking at up to 150 MHz and Serial Wire Output (SWO) using Manchester and UART, clocking at up to 200 Mbps. The trace data is collected by the C-SPY Debugger in IAR Embedded Workbench and can be visualised and analysed in various windows. I-jet Trace is a new addition to IAR Systems’ lineup of in-circuit debugging probes. The product portfolio covers different needs from initial to more advanced development and is targeted for simplified, seamless and more flexible development workflows. All products are integrated with IAR Embedded Workbench. The complete debugging solution provided by I-jet Trace and C-SPY also includes Power Debugging. This technology provides developers with information about how the software implementation of an embedded system affects the system’s power consumption. IAR Systems www.iar.com GaN driver amplifier serves X-band RFMW has announced design and sales support for the TGA2627-SM. This 32 dBm Psat GaN driver comes packaged as a 5- x 5-mm, air-cavity ceramic QFN providing an SMT advantage over DIE based competitors. The push-pull internal configuration provides low harmonic content of <40 dBc over the 6 to 12 GHz frequency span. Small signal gain is rated at >27 dB. Target markets for the TriQuint TGA2627-SM include radar, EW and communication systems. Using a 25V bias and drawing only 200mA, the TGA2627-SM is compatible with TriQuint’s high power amplifiers, easing the burden of multiple bias supplies. RFMW www.rfmw.com Renesas processors for industrial automation have built-in networking Renesas’ RZ/T1 Real-Time Processor comprises a real-time CPU with up to 600 MHz operation and the R-IN engine, offering both real-time control and deterministic network connectivity for industrial equipment The RZ/T1 Group is a factory automation solution with built-in industrial network functionality for use in many industrial applications such as AC servo drives, motion controllers, inverter control and general industrial equipment that require high speed, responsiveness, and excellent real-time performance. Demand for improvements in performance and network connectivity are addressed by combining high-performance, real-time control and multi-protocol industrial Ethernet communication functions on a single chip. The RZ/T1 group of devices is built around the ARM Cortex-R4F core operating at up to 600 MHz and is configured with two regions of tightly coupled memory, which is linked directly to the CPU core, removing the need for cache memory. TCMs support critical routines, such as interrupt handling routines or real-time tasks, ensuring the highest level of responsiveness with no cache latency. The RZ/T1 also integrates the R-IN Engine industrial Ethernet communication accelerator. It provides the same multi-protocol features as the Renesas R-IN Series, with support for multiple industrial Ethernet communication standards, including EtherCAT. Renesas says that traditional solutions such as high-frequency microprocessors (MPUs) with cache memory are unsuited for real-time control because of the unpredictability characteristics of cache memory. And, while microcontrollers (MCUs) with on-chip flash memory are likewise marketed for real-time control, the increasing performance requirements are driving them to hit their performance ceiling. Deterministic, open standard networks such as Ether- CAT, Ethernet/IP, and PROFINET are becoming mainstream in all types of industrial equipment. Supporting such standards typically requires the use of a separate ASIC with dedicated communication functionality, which leads to increased system cost and circuit board footprint. Renesas www.renesas.eu BeagleBone Black, Raspberry Pi run Pico scope… in beta Pico Technology has released beta drivers for its oscilloscope and data logging devices to run on the popular ARM-based BeagleBone Black and Raspberry Pi development boards. The drivers give programmers access to a great variety of compact, economical USB oscilloscopes and data loggers, ranging from very basic configurations to high-speed oscilloscopes with bandwidths up to 500 MHz, high-resolution 12-bit and 16-bit oscilloscopes, and deep-memory oscilloscopes with buffer sizes up to 512 MS. Most PicoScope oscilloscopes also offer advanced digital triggering, fast block-mode and streaming-mode data capture, and a built-in signal generator or arbitrary waveform generator. The data logger range includes multichannel voltage loggers, 8-channel thermocouple loggers and the educational DrDAQ multifunction logger. Separate driver packages and snippets of C code are available for Raspbian and Debian systems. Similar code could be developed in C-compatible programming languages such as C++, Java and JavaScript. As beta products, these drivers are explained and supported on our forum at: Pico Technology www.picotech.com 42 Electronic Engineering Times Europe December 2014 www.electronics-eetimes.com
