Imsys has developed a dual-core, runtime-reconfigurable processor that can run at 350 MHz with an active power consumption of 19.7 µW/MHz using one core. Intended for low-power applications, 97% of the processor’s transistors are used in memory blocks. The cores share memories and a five-port grid network router (NoC). Memory management is handled by microcode, and memory is closely integrated with the processor without the need for an ordinary cache controller. The active consumption of each core—executing from RAM, including its consumption there—is 6.9 mW at 350 MHz.
Imsys’s processor is suitable for sensor nodes powered by energy harvesting in the Internet of Things (IoT), as well as in many-core chips for microservers and robotics. Microcode, as opposed to logic gates, is compact and energy efficient. Imsys uses extensive microprogramming to accomplish a rich set of instructions, thereby reducing the number of cycles needed without energy inefficient speculative activity and duplicated hardware logic. Each core has two instruction sets, one of which executes Java and Python directly from the dense JVM bytecode representation. C code is compiled to the other set with unparalleled density. Internal microcode is used for computationally intensive standard routines, such as crypto algorithms, which would otherwise be assembly coded library routines or even special hardware blocks. Optimizing CPU intensive tasks by microcode can reduce execution time and energy consumption of by more than an order of magnitude compared to C code.
The rich instruction set optimized for the compiler reduces the memory needed for software. And just like the microcoded algorithms, it reduces the number of clock cycles needed for execution. This platform has a certified JVM and uses an RTOS kernel certified to ISO 26262 safety standard for automotive applications. The development tools will be enhanced with the support enabled by the LLVM infrastructure. A new instruction set optimized for an LLVM backend has been developed and is being implemented in the coming hardware generation.

Linx Technologies recently introduced new pre-certified remote control and sensor transceiver modules. Built on the Hummingbird platform, the HumRC Series transceiver is a frequency hopping spread spectrum (FHSS) transceiver designed for reliable bidirectional remote control and sensor applications. Available in 900 MHz, the HumRC outputs up to 10 dBm, which results in a line-of-sight range of up to 1 mile.
The HumRC Series module is a completely integrated RF transceiver and processor designed for bidirectional remote control. It employs a fast-locking FHSS system for noise immunity and higher transmitter output power as allowed by government regulations.
The remote control transceiver has eight status lines that can be individually configured as inputs to register button presses or as outputs to drive application circuitry. A selectable acknowledgement indicates that the transmission was successfully received. Primary settings are hardware-selectable, which eliminates the need for an external microcontroller or other digital interface.
The transceiver also has two analog-to-digital (ADC) inputs for sensors or circuits that output an analog voltage. The module can automatically respond to a command with these values, so a sensor node does not need an additional microprocessor.
To aid rapid development, the HumRC Series low-cost RF modules are available as part of a newly conceived type of Master Development System. This development kit is intended to assist in the rapid evaluation and integration of the HumRC Series data transceiver modules. It features several preassembled evaluation boards that include everything needed to quickly test the operation of the transceiver modules.

Some people like to remotely start their cars when it’s cold outside. Dan Beadle took this idea one step further by Internet-enabling his mountainside retreat’s hydronics system. The innovative design enables him to warm the house well in advance of his arrival.
Serving up the current temperature involves several computers, a Wi-Fi access point, and a DPAC Airborne module.
In “Wireless Water Heater” (Circuit Cellar 163), Beadle writes:
My mountain home, where I have vacationed for years, is well insulated, making it a snap for the heater system to keep warm. I have a small, efficient heater; however, it takes forever to warm the house from a 50°F standby to a livable 68°F. Typically, I arrive late and shiver in my jacket for three or four hours until the house warms up—and that does not warm the entire house, just the portion needed to get through the night.
I had been thinking for a while about Internet-enabling the system. The idea was to turn on the heater before we start up the mountain. I have DSL at the house with a fixed IP. So, it seemed like it would be a simple task to enable a thermostat. I considered using an X10 thermostat, but, after a few of our X10-enabled lights found a mind of their own, I decided that I wanted better reliability. My next thought was to use simple copper to do the hook-up. I started planning a cable from my office/DSL entry up to the logical thermostat location. Then I procrastinated. I could not bring myself to run the wires along the surface of my redwood paneling. (And it was not at all feasible to remove the paneling.) Wireless makes the problem a lot simpler: there are no wires to run, and the applications processor and digital I/O on the module make the hardware design trivial.
