Figure 5. Data Memory Map
Data Memory
Data Memory (Full Memory Mode) is a 16-bit-wide space
used for the storage of data variables and for memory-mapped
control registers. The ADSP-2188M has 56K words on Data
Memory RAM on-chip. Part of this space is used by 32 memory-
mapped registers. Support also exists for up to two 8K external
memory overlay spaces through the external data bus. All internal
accesses complete in one cycle. Accesses to external memory are
timed using the wait states specified by the DWAIT register and
the wait state mode bit.
Data Memory (Host Mode) allows access to all internal memory.
External overlay access is limited by a single external address
line (A0).
Memory Mapped Registers (New to the ADSP-2188M)
The ADSP-2188M has three memory mapped registers that differ
from other ADSP-21xx Family DSPs. The slight modifications
to these registers (Wait State Control, Programmable Flag and
Composite Select Control, and System Control) provide the
ADSP-2188M’s wait state and
BMS control features. Default
bit values at reset are shown; if no value is shown, the bit is unde-
fined at reset. Reserved bits are shown on a grey field. These bits
should always be written with zeros.
