Figure 29. DSP, MCU, and Memory Interfaces
The Delay Memory Interface (DMIF) is the interface block between the DSP core and the delay memory. The
DMIF blocks primary purpose is to keep track of twenty four sets of delay memory pointers that are initially set up
by the micro controller through an I2C command(s). Eight of the pointers are used to write/retrieve 48-bit data
(full-precision intermediate) and the other sixteen for 24-bit data (post quantized). Thus to support 48-bit word
reverb delay, two RAM locations must be used.
