pulse Intel Edison embedded/IoT development platform, now in distribution RS Components now has the complete Intel Edison development platform, which includes: the ultra-small Intel Edison compute module; the Intel Edison breakout board that helps rapid prototyping; and the Intel Edison board for Arduino. The Intel Edison module is a highly miniaturised product-ready compute module built using an advanced 22nm System-on-Chip (SoC) that includes a dual-core, dualthreaded 500 MHz Intel Atom CPU and a 100 MHz 32-bit Intel Quark microcontroller. Connectivity is provided, and built-in Wi-Fi and Bluetooth Low Energy suit this module for Internet of Things (IoT) applications. A device-to-device and device-to-cloud connectivity framework is also integrated. Programmable RF dual transceiver implements MIMO-on-a-chip Lime Microsystems is shipping its second generation Field Programmable Radio Frequency (FPRF) devices. The FPRF contains dual transceivers that cover the frequency range 0.1 to 3800 MHz. The fully programmable, low power chips cover all the cellular bands used in 2G, 3G and 4G networks, as well as many commercial and military bands. Parameters such as gain and filter bandwidth are also fully in-system programmable, making the device a highly flexible RF solution for a wide range of wireless applications. The dual transceivers are can implement Multiple-In, Multiple- Complete article, here Complete article, here Instruction smart trace on 8051-derivative cores – smart & non-intrusive Polish silicon IP company Digital Core Design has enhanced its 8051 portfolio with the functionality of an Instruction Smart Trace. Starting from the most popular DP8051, through the DP80390, to the fastest 8051-architecture core, the DQ8051 – can all efficiently reduce trace memory size and increase traced program history. Instruction Smart Trace is an inherent part of the DoCD Hardware Debugger, which provides debugging capability for System-on-Chip (SoC) designs. Unlike other on-chip debuggers, the tool provides non-intrusive debugging of a running application and saves designer’s time, thanks to the hardware trace, called Instructions Smart Trace buffer (IST). Plugging the 35.5mm x 21.0mm x 3.9mm Intel Edison module into the breakout board exposes the module’s 1.8V I/Os, and allows connection via the board’s USB Micro Type-AB connector. The board also provides a DC power-supply jack, batterycharger circuit, and USB OTG power switch. The Intel Edison expansion board for Arduino is hardware and software pin-compatible with Arduino shields designed for the Uno R3. The board provides important connections in the same locations as on the Arduino Uno R3, and also has a Micro SD card connector as well as micro and standard-size USB connectors. Out (MIMO) systems with a digital bandwidth up to 60 MHz in each channel. The LMS7002M includes user-programmable DSP that can equalise the gain and phase of a MIMO system, or enhance the analogue filtering to provide lower power consumption. The low power chip uses a 65 nm CMOS process, and consumes 550 mW in single-in single-out (SISO) mode or 800 mW when configured for MIMO operation. The device can operate using a single 1.8V supply rail, and requires a minimum of external components. The DoCD-IST captures instructions in a smart and nonintrusive way, so it doesn’t capture addresses of all executed instructions, but only these related to the start of tracing, conditional jumps and interrupts. This method not only saves time, but also allows improving the size of the IST buffer and extending the trace history. “For example, by using 256 Bytes of trace memory, we can store 128 program branches and decode much more program history, since the executed program is composed of normal opcodes (mov, add, mul, anl, etc.) and branches,” explains Tomek Krzyżak, VCEO of Digital Core Design.
