Nomadik is a family of microprocessors for multimedia applications from STMicroelectronics, and later ST-NXP Wireless. It was originally based on the ARM9 ARM architecture(s), and was designed specifically for use in mobile devices.
The i.MX range is a family of Freescale Semiconductor proprietary microcontrollers for multimedia applications based on the ARM architecture and focused on low-power consumption. The i.MX application processors are SoCs (System-on-Chip) that integrate many processing units into one die, like the main CPU, a video processing unit, and a graphics processing unit for instance. The i.MX products are qualified for automotive, industrial, and consumer markets. Most of them are guaranteed for a production lifetime of 10 to 15 years.
Devices that use i.MX processors include Ford Sync, the Amazon Kindle and Kobo eReader series of e-readers until 2021, Zune, Sony Reader, Onyx Boox readers/tablets, SolidRun SOM's, Purism's Librem 5, some Logitech Harmony remote controls and Squeezebox radio and some Toshiba Gigabeat MP4 players. The i.MX range was previously known as the "DragonBall MX" family, the fifth generation of DragonBall microcontrollers. i.MX originally stood for "innovative Multimedia eXtension".
LDMOS is a planar double-diffused MOSFET used in amplifiers, including microwave power amplifiers, RF power amplifiers and audio power amplifiers. These transistors are often fabricated on p/p+ silicon epitaxial layers. The fabrication of LDMOS devices mostly involves various ion-implantation and subsequent annealing cycles. As an example, the drift region of this power MOSFET is fabricated using up to three ion implantation sequences in order to achieve the appropriate doping profile needed to withstand high electric fields.
TriMedia is a family of very long instruction word media processors from NXP Semiconductors. TriMedia is a Harvard architecture CPU that features many DSP and SIMD operations to efficiently process audio and video data streams. For TriMedia processor optimal performance can be achieved by only programming in C/C++ as opposed to most other VLIW/DSP processors which require assembly language programming to achieve optimal performance. High-level programmability of TriMedia relies on the large uniform register file and the orthogonal instruction set, in which RISC-like operations can be scheduled independently of each other in the VLIW issue slots. Furthermore, TriMedia processors boast advanced caches supporting unaligned accesses without performance penalty, hardware and software data/instruction prefetch, allocate-on-write-miss, as well as collapsed load operations combining a traditional load with a 2-taps filter function. TriMedia development has been supported by various research studies on hardware cache coherency, multithreading and diverse accelerators to build scalable shared memory multiprocessor systems.
The ARM Cortex-A9 MPCore is a 32-bit multi-core processor that provides up to 4 cache-coherent cores, each implementing the ARM v7 architecture instruction set. It was introduced in 2007.

RF CMOS is a metal–oxide–semiconductor (MOS) integrated circuit (IC) technology that integrates radio-frequency (RF), analog and digital electronics on a mixed-signal CMOS RF circuit chip. It is widely used in modern wireless telecommunications, such as cellular networks, Bluetooth, Wi-Fi, GPS receivers, broadcasting, vehicular communication systems, and the radio transceivers in all modern mobile phones and wireless networking devices. RF CMOS technology was pioneered by Pakistani engineer Asad Ali Abidi at UCLA during the late 1980s to early 1990s, and helped bring about the wireless revolution with the introduction of digital signal processing in wireless communications. The development and design of RF CMOS devices was enabled by van der Ziel's FET RF noise model, which was published in the early 1960s and remained largely forgotten until the 1990s.
