The memory map of the VPI Control I/F for the Scaler coefficients is shown in Figure 12-32. All coefficients can be filled up by a single VPI Control write command. The update address feature of VPI Control I/F enables individual access to a certain location of memories.
The module supports the VPI Control Read to read back the contents in the coefficient memories for debug purpose. Figure 12-33 shows the memory map of the VPI Control Read. As the VPI Control Read has only 32 bit data bus, it requires the word addressing while the write does the quad-word addressing.
