Digital signal processing (DSP) is a branch of computer science and engineering that enables the manipulation and analysis of digital signals. Digital signal processors (DSPs) are dedicated processors or application-specific integrated circuits (ASICs) that are specifically designed to process digital signals. DSPs are widely used in a variety of embedded systems to perform tasks such as digital filtering, signal modulation, image processing and speech processing.

The TMS320DM642AZDK7 (AZDK7) is a high-end DSP from Texas Instruments. It is part of the TMS320DM64x/TMS320DMC64x family and is based on the TMS320C64x+™ VLIW CPU core. The TMS320DM642AZDK7 is a single or two-chip solution. It combines a 304 MHz dual-core DSP, peripherals, and memory onto a single package. The device is designed for often timeline-critical applications such as signal and image processing, real-time video processing, and communications.

One of the main applications of the TMS320DM642AZDK7 is video processing. The device has an integrated video display controller (VDC), which is compatible with television broadcasting standards such as NTSC/PAL. In addition, the DSP also supports up to 1080p HD (high-definition) video for decoding and encoding. Additionally, the device is capable of decoding MPEG2, MPEG4, and H.264 video codecs.

Another main application of the TMS320DM642AZDK7 is real-time audio processing. The integrated audio coprocessor is capable of processing up to 8 channels of digital audio simultaneously, at sample rates of up to 48 kHz. Additionally, the device is also capable of playing back up to 32 channels of digital audio. The TMS320DM642AZDK7 also includes an array of integrated analog peripherals, making it suitable for a wide range of audio applications.

Image processing is another field of application for the TMS320DM642AZDK7. The device has support for grayscale and color image processing. The integrated video port and DMA controller is capable of transferring image data at high speeds. The device also supports a variety of image formats such as JPEG and BMP. The DSP also has an integrated enhancer that can be used to enhance and improve the quality of images.
