The Motorola DSP56000 is a family of digital signal processor (DSP) chips produced by Motorola Semiconductor starting in 1986 with later models are still being produced in the 2020s. The 56k series was intended mainly for embedded systems doing signal processing, but was also quite popular for a time in a number of computers, including the NeXT, Atari Falcon030 and SGI Indigo workstations all using the 56001. Upgraded 56k versions are still used today in audio equipment, radar systems, communications devices and various other embedded DSP applications. The 56000 was also used as the basis for the updated 96000, which was not commercially successful.

OpenMAX, often shortened as "OMX", is a non-proprietary and royalty-free cross-platform set of C-language programming interfaces. It provides abstractions for routines that are especially useful for processing of audio, video, and still images. It is intended for low power and embedded system devices that need to efficiently process large amounts of multimedia data in predictable ways, such as video codecs, graphics libraries, and other functions for video, image, audio, voice and speech.
Silvaco Group, Inc., develops and markets electronic design automation (EDA) and technology CAD (TCAD) software and semiconductor design IP (SIP). The company is headquartered in Santa Clara, California, and has offices in North America, Europe, and throughout Asia. Founded in 1984, Silvaco is a privately held EDA company. The company has been known by at least two other names: Silvaco International, and Silvaco Data Systems.
A mixed-signal integrated circuit is any integrated circuit that has both analog circuits and digital circuits on a single semiconductor die. Their usage has grown dramatically with the increased use of cell phones, telecommunications, portable electronics, and automobiles with electronics and digital sensors.
I²S, is an electrical serial bus interface standard used for connecting digital audio devices together. It is used to communicate PCM audio data between integrated circuits in an electronic device. The I²S bus separates clock and serial data signals, resulting in simpler receivers than those required for asynchronous communications systems that need to recover the clock from the data stream. Alternatively I²S is spelled I2S or IIS. Despite the similar name, I²S is unrelated to the bidirectional I²C (IIC) bus.
The iPod Shuffle is a discontinued digital audio player designed and formerly marketed by Apple Inc. It was the smallest model in Apple's iPod family, and was the first iPod to use flash memory. The first model was announced at the Macworld Conference & Expo on January 11, 2005; the fourth- and final-generation models were introduced on September 1, 2010. The iPod Shuffle was discontinued by Apple on July 27, 2017.
Conexant Systems, Inc. was an American-based software developer and fabless semiconductor company that developed technology for voice and audio processing, imaging and modems. The company began as a division of Rockwell International, before being spun off as a public company. Conexant itself then spun off several business units, creating independent public companies which included Skyworks Solutions and Mindspeed Technologies.
A portable media player (PMP) or digital audio player (DAP) is a portable consumer electronics device capable of storing and playing digital media such as audio, images, and video files. The data is typically stored on a compact disc (CD), Digital Versatile Disc (DVD), Blu-ray Disc (BD), flash memory, microdrive, SD cards or hard drive; most earlier PMPs used physical media, but modern players mostly use flash memory. In contrast, analogue portable audio players play music from non-digital media that use analogue media, such as cassette tapes or vinyl records.
Realtek Semiconductor Corp. is a fabless semiconductor company situated in the Hsinchu Science Park, Hsinchu, Taiwan. Realtek was founded in October 1987 and subsequently listed on the Taiwan Stock Exchange in 1998. Realtek currently manufactures and sells a variety of microchips globally and its product lines broadly fall into three categories: communications network ICs, computer peripheral ICs, and multimedia ICs. As of 2019, Realtek employs 5,000 people, of whom 78% work in research and development.
Intel High Definition Audio (IHDA) (also called HD Audio or development codename Azalia) is a specification for the audio sub-system of personal computers. It was released by Intel in 2004 as the successor to their AC'97 PC audio standard.
Integrated circuit design, semiconductor design, chip design or IC design, is a sub-field of electronics engineering, encompassing the particular logic and circuit design techniques required to design integrated circuits, or ICs. ICs consist of miniaturized electronic components built into an electrical network on a monolithic semiconductor substrate by photolithography.
The following is a list of H.264/MPEG-4 AVC products and implementations.
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".
