Samsung Electronics president Young Sohn was at the Internet of Things World conference yesterday in San Francisco to introduce a new family of low-power chips designed for the next generation of IoT devices.
One of the new chips presented on stage is called ARTIK 1 and features a MIPS32-based, dual-core application processor, flash storage, a crypto engine and Bluetooth Smart radios for communication.
Delving into the underlying architecture of the CPU cluster, we find two MIPS microAptiv processors: one configured for high-performance workloads and clocked at 250 MHz, and a low-power variant at 80 MHz. The modified diagram below highlights the two MIPS microAptiv CPUs at the heart of the ARTIK 1 chip:
Here is what the official page from Samsung says about the ARTIK 1 processor:
ARTIK 1 has the world’s smallest form factor (12mm x 12mm) in its class. Aimed especially at power-sensitive devices, ARTIK 1 provides weeks of use on a single charge. Its hardware includes a 9-axis motion sensor with gyroscope, accelerometer and magnetometer, as well as Bluetooth low energy connectivity. With a feature set tailored for wearables and IoT end nodes, ARTIK 1 is a mobile workhorse.
MIPS microAptiv quick facts
Ticking inside the ARTIK 1 chip, microAptiv is part of the award-winning Aptiv family and implements a five-stage pipeline architecture; here is how the two flavors above differentiate:
- microAptiv UP features a cache controller and a Memory Management Unit (MMU) for embedded systems that run rich operating systems.
- microAptiv UC includes a Memory Protection Unit (MPU) for fast execution of real-time operating systems
Samsung also presented plans for a complete datacenter-to-device software infrastructure designed around security. microAptiv features a secure debug interface which ensures a high level of security, and can provide added hardware-assisted safety for the main application processor.
MIPS microAptiv CPUs are based on an elegant RISC architecture which achieves better performance at lower frequencies and in a smaller area compared to competing solutions. For embedded and microcontroller-type applications, MIPS microAptiv offers class-leading performance: 1.7 DMIPS/MHz and 3.6 CoreMark/MHz.
Application developers will also benefit from a significant boost in DSP operations too (e.g. voice processing) since microAptiv offers up to 2.56x higher DSP performance versus the competition.
Finally, microAptiv CPUs support microMIPS, a code compression ISA designed to reduce memory requirements for embedded systems.
