One of the recent significant developments in ultrasound is the emergence of portable and handheld ultrasound machines and their rapid acceptance in the market place.
Because of their power efficiency and high performance, digital signal processor (DSP) based devices have been increasingly used as the main processing engine in these portable and hand carried units.
This application report discusses major requirements and key challenges of implementing highly efficient scan conversion on DSP, as well as the key features and major design considerations for achieving high efficiency. It introduces TI’s efficient scan conversion software implementation for TI C64x+™ based DSP devices. Performances are provided, in terms of cycles per pixel and total number of MHz consumed by the scan converter.
