Memory Interface
The KS8695PX has a glueless interface for SDRAM and
static memory, i.e. ROM, SRAM, and Flash. It supports up
to two banks of static memory (Figure 7), up to two banks of
SDRAM (Figure 8), and three banks of external I/O (Figure
9). The total address space for the KS8695PX is 64MB.
This includes SDRAM, static memory, external I/O, and the
KS8695PX's own 64KB of register space.
The memory interface for the SDRAM and static memory has
a special automatic address mapping feature. This allows the
designer to connect address bit 0 on the memory to ADDR[0]
ontheKS8695PXandaddressbit1onthememorytoADDR[1]
on the memory, regardless of whether the designer is trying
to achieve word, half word, or byte addressing.
The KS8695PX memory controller performs the address
mapping internally. This permits the designer to use the
maximum amount of address bits, instead of losing one
or two bits because of address mapping. For external I/O,
however, the designer still needs to take care of the address
mapping (see Figure 9).
