I will to use the DMA to transfer data from DDR Controller directly to the LCDC Controller with the DMA engine. For the first calculation i need the Peak transfer rate for this transfer. In the user manual from K70 i find only the transfer rate for SRAM to Peripherial Device, not for Peripheral- to Peripheral-Device.
Is the DMA to be apple to solve this transfer? And what's about the max. Transfer Rate?
Hi Kai, the DMA can perform the transfer from the DDR controller to the LCDC, it counts as a 32b internal bus to internal SRAM memory transfer so you can use the following transfer rate table:
66.7 MHz, 32b 66.7
83.3 MHz, 32b 83.3
100.0 MHz, 32b 100.0
133.3 MHz, 32b 133.3
150.0 MHz, 32b 150.0
Hi Pedro,
many thanks for the answer.
