| Abstract: | The host port interface (HPI) is an 8-bit parallel port used to interface a host processor or device to the Texas Instruments (TI) digital signal processor (DSP).The HPI enables the DSP to interface to host processors (typically microcontrollers) bidirectionally with minimal or no external interface logic.In this paper,the basic theory of HPI is described.Also, the hardware interface and a software protocol to communicate between the TMS320VC5402 DSP and the MSP430X33X mixed signal microcontroller are presented. |
