purpose of using daram in dsp processors

Program memory can be ROM, Dual Access RAM (DARAM), Single Access RAM
(SARAM), or a combination of all these. The program memory can be extended
externally to 8192K words. That is, 128 pages of 64K words each.

One set of address bus and data bus is available in the
case of SARAM and two sets of address bus and data bus is available in the case of
DARAM. The DSP can thus access two memory locations simultaneously.
