11 / 44 page  SM320C32EP DIGITAL SIGNAL PROCESSOR SGUS038 − AUGUST 2002 11 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 external memory interface (continued) D For 32-bit-wide physical memory, all STRB0 and STRB1 pins function as byte-enable (chip-select) pins. See Figure 4.

C32 With 32-Bit-Wide External Memory For more detailed information and examples, see TMS320C32 Addendum to the TMS320C3x User’s Guide (literature number SPRU132B) and Interfacing Memory to the SMQ320C32 DSP Application Report (literature number SPRA040). D The IOSTRB control signal, like STRB0 and STRB1, is also mapped to a specific range of addresses but it is a single signal that can access only 32-bit data from 32-bit-wide memory. Its range of addresses appears in Figure 8, the SM320C32-EP memory map. The IOSTRB bus timing is different from the STRB0 and STRB1 bus timings to accommodate slower I/O peripherals. examples Figure 5 and Figure 6 show examples of external memory configurations that can be implemented using the SM320C32-EP external memory interface. The first example has a 32-bit-wide external memory with 8- and 16-bit data areas and a 32-bit program area. |
