1:06 PM | 0.1KB/s expert.chegg.com/qr + Practice Question C c [10] 54 Solved: 3 Question 7 (10 points) In the DMA block diagram below, when all 7 of the DMA channels are configured and set with an equal priority, and all copies take equal time, select which of the following statements are true (select all that apply). 0000 System Cortex-MO FLITF Flash SRAM DMA Ch.2 DMA Reset & clock CRC GPIOA GPIOB control (RCC) Bridge Arbiter Ch.7 APB GPIOC GPIOD GPIOE GPIOF AHB Slave DMA request ADC DAC SPI1/1251 SP12/1252 USART1 TIM USART2 TIM2 12C2 TIM3 12C1 TIME TIM7 TIM15 USART3 USART4 TIME TIM17 MS19218V5 In any given AHB bus cycle, there will be 7x the DMA traffic versus having only one channel active. The DMA engine will demand the AHB bus 7x more than if just one of these channels is active. The Cortext-MO must have a higher priority than the DMA engine to avoid interference. The DMA controller will be unable to communicate with elements on the APB (Advanced Peripheral Bus). The DMA controller can only service 2 channels at a time and the rest will be pending.
