The '''Parallel Peripheral Interface''' ('''PPI''') is a peripheral found on the [[Blackfin]] embedded processor. The PPI is a [[half-duplex]], [[Two-way communication|bi-directional]] port that is designed to connect directly to [[LCD]]s, [[CMOS sensor]]s, [[Charge-coupled device|CCD]]s, video encoders (video [[Digital-to-analog converter|DAC]]s), video decoders (video [[Analog-to-digital converter|ADC]]s) or any generic high speed, parallel device.<ref>{{Cite web|title=PPI: Parallel Peripheral Interface [Analog Devices Wiki]|url=https://wiki.analog.com/resources/eval/sdp/sdp-b/peripherals/ppi|access-date=2021-10-01|website=wiki.analog.com}}</ref>
The width of the PPI is programmable and can be set between 8 and 16 bits in 1-bit increments. The latest Blackfin family (BF54x) also features an 18/24-bit PPI for direct connection to [[RGB]] LCD panels.
