Abstract
The present disclosure provides an improved point-to-point serial peripheral interface, a system comprising an improved point-to-point serial peripheral interface, and a method for use in a system comprising an improved point-to-point serial peripheral interface. A master comprises a SPI initiating port. Each slave comprises at least one SPI receiving port and at least one SPI forwarding port. The master provides a set of SPI signals to the SPI receiving port of the first slave in the chain, and the entire SPI signals are forwarded via the SPI forwarding port of each of the slaves until the SPI transaction reaches a target slave, which is identified by an in-band device addressing mechanism.
