Texas Instruments (TI) is one of the world's top 10 semiconductor companies. At the same time, TI is also the world's largest manufacturer of analog circuit technology components. TI is headquartered in Texas, USA, and its history can be traced back to 1930. In 1982, TI released the world's first single-chip digital signal processor (DSP), and then became the leader in this field. Although TI was mainly engaged in arms supply at the beginning, what really made TI famous was its achievements in signal processing and analog circuits. In addition to providing analog technology, digital signal processing (DSP), and microcontroller (MCU) semiconductors, TI is also committed to the research and development and production of automotive and industrial equipment chips. At present, TI's three main DSP product series are the C2000 series (mainly used in digital control systems); the C5000 series (C54x, C55x) mainly used for low-power, portable wireless communication terminal products; and the C6000 series mainly used for high-performance and complex communication systems. The TMS320C54x series DSP chips in the C5000 series are widely used in communications and personal consumer electronics.
