Abstract: PDT transfer of EMIF interface is a specific data transmission mode of TMS320C64xx series DSP. Firstly the EMIF interface of C64xx DSP is introduced, then the PDT transfer’s conception, basic operation and transfer sequences are given. At last some essentials are shown when using PDT mode in a DSP system.
