16-bit host-port interface (HPI16)  
The HPI16 is an enhanced 16-bit version of the C54x 8-bit host-port interface (HPI). The HPI16 is designed to  
allow a 16-bit host to access the DSP on-chip memory, with the host acting as the master of the interface.  
Figure 6 illustrates the available memory accessible by the HPI. It should be noted that neither the CPU nor DMA  
I/O spaces can be accessed using the host-port interface.
