The HPI8 functions as a slave and enables the host processor to access the on-chip memory of the 5402.A
major enhancement to the 5402 HPI over previous versions is that it allows host access to the entire on-chip
memory range of the DSP.The HPI8 memory map is identical to that of the DMA controller shown in Figure 7.
The host and the DSP both have access to the on-chip RAM at all times and host accesses are always
synchronized to the DSP clock.If the host and the DSP contend for access to the same location,the host has
priority,and the DSP waits for one HPI8 cycle.Note that since host accesses are always synchronized to the
5402 clock,an active input clock (CLKIN) is required for HPI8 accesses during IDLE states,and host accesses
are not allowed while the 5402 reset pin is asserted.
