Integrity RTOS extended to multicore ARM Cortex-A9 processors Green Hills Software now offers its INTEGRITY-178 tuMP real-time operating system (RTOS) for ARM-based processors. Green Hills Software partner Richland Technologies has announced an Open Standard Reconfigurable and Certifiable Computing Architecture (ORCCA) avionics computer based on an ARM multicore processor and INTEGRITY-178 tuMP. The INTEGRITY 178 tuMP (time-variant unified multiprocessing) RTOS is intended for safety-critical and security-critical systems that are based on modern multicore processors. INTEGRITY-178 tuMP significantly improves the flexibility in how the ARM processor cores can be used. The tuMP architecture is referred to as “unified” in that a common OS controls the scheduling of all cores and the overall communications between applications. It retains all AMP and SMP scheduling capabilities while resolving their significant limitations. The introduction of tuMP for ARM-based processors follows the successful introduction in 2011 of INTEGRITY-178 tuMP for Freescale’s family of QorIQ multicore processors. The tuMP implementation is an update to Green Hills Software’s INTEGRITY-178 single-core product; INTEGRITY-178 tuMP for ARM also supports the ARINC-653 (Part 1 supplement 3 and Part 2 supplement 2) interfaces and operating system capabilities necessary to be aligned with the Future Airborne Capability Environment (FACE™) V2.0 Technical Standard. For systems requiring compliance to RTCA/ DO-178B/C, Green Hills Software provides Level A certification evidence for INTEGRITY-178 tuMP. Green Hills Software www.ghs.com Automotive-qualified motor controller combines small size and high current Microchip has developed an automotive-qualified motor driver IC that combines cost-effectiveness with a very small footprint. The MCP8063 comes in a small 8-pin, 4x4mm DFN package. Microchip claims that this is the world’s first motor driver to combine a this size with a 1.5A peak phase current for the 180° sinusoidal drive of a variety of three-phase brushless DC motor and fan applications. The high degree of integration reduces PCB area and the high sinusoidal-drive performance provides high efficiency, low mechanical vibration and, as a consequence, low acoustic noise and silent operation. The device also includes safety features such as thermal shutdown, over-current limiting and lock-up protection. Additionally, it supports the sensorless driving of BLDC motors, which eliminates the cost and space of a Hall sensor. The MCP8063 motor driver works stand-alone or in conjunction with Microchip’s portfolio of PIC microcontrollers and dsPIC digital signal controllers. This offers a high degree of flexibility for everything from simple voltage control to closed-loop motor speed control using high-performance algorithms, such as sinusoidal sensorless drive. Development with the MCP8063 motor driver is facilitated by the 12V 3-phase BLDC sensorless Fan Controller Demo Kit ADM00575. Microchip Technology www.microchip.com ARM-based kit enables Apple-compatible accessories Silicon Labs has a 32-bit hardware and firmware development kit designed to accelerate the design of Made for iPod/ iPhone/iPad (MFi) accessories and help product manufacturers get to market quickly. Based around the company’s ARM Cortex-M3-based SiM3U microcontroller (MCU), the MFI-SIM3U1XX-DK development kit supports the all-digital Lightning connector and protocol stack. The development kit targets a wide range of accessories for iOS devices including entertainment accessories, device-powered dongles, game controllers and docking stations. Silicon Labs designed the MFI-SIM3U1XX-DK kit as a turnkey solution to help developers simplify their Lightning-based accessory development projects and speed time to market while meeting the MFi program requirements. The kit provides a cost-effective and comprehensive solution for accessory developers and includes hardware development board, firmware libraries and an example iOS App, which supports Appcessory-style communication between the iOS device and development board. The SiM3U MCU features fully-specified analogue peripherals, an integrated capacitive touch sense controller, an internal 5V regulator and crystal-less USB support, which eliminates the need for discrete crystal oscillators and reduces component count, BOM and board space. Silicon Labs www.silabs.com/mcu Companion FPGA packs 85K LUTs in 10x10mm package The ECP5 FPGA Family launched by Lattice Semiconductor was specifically designed to focus on key fast growing and high-volume markets such as small-cells, microservers, broadband access, or industrial video. As a companion chip bringing the much needed design flexibility to ASICs and ASSPs, the IC comes in various options offering from 25 to 85K look-up tables (LUTs) at a cost 40% lower than alternatives according to the manufacturer, while delivering twice the functional density of competing solutions. The devices are specifically designed to closely match a number of applications, with improvements on the DSP block and support for very low cost and low power SERDES links. The ECP5 FPGAs provide the flexible connectivity required in outdoor small-cells, at extremely low-cost. They can also enable a smart SFP (small form-factor pluggable) transceiver solution for broadband access equipment, including integrated operation and maintenance. Outside of communications, ECP5 devices offer low cost, low power PCI Express side-band connectivity for microservers. For industrial video cameras, ECP5 FPGAs can implement the entire image processing functionality in a device that consumes under 2W. Enhancements leading to 30% lower total power than other FPGA solutions include stand-by mode operation of the individual blocks including SERDES, dynamic IO bank controllers and reduced operating voltage.
