DMA priority levelEach DMA channel can be independently assigned high priority or low priority relative to each other.MultipleDMA channels that are assigned to the same priority level are handled in a round-robin manner.DMA source/destination address modificationThe DMA provides flexible address-...
The article reports that financial services firms and network providers are strengthening their direct-market access (DMA) tools to prepare for a resurgence. According to Chris Wolf, managing partner and co-chief investment officer of Cogo Wolf Asset Management, there are several attractive investment...
Hi , Thanks for reply . I want give more priority to DMA controller over CPU . Can you tell me the API's to set it.

Job PriorityTo specify the priority of a job, simply invoke the priority() method with a number, or priority name, which is mapped to a number.queue.create('email', { title: 'welcome email for tj' , to: 'tj@learnboost.com' , template: 'welcome-email' }).priority('high').save()...
A priority circuit controls the respective priorities assigned to various types of DMA to ensure that all types of DMA demands can be accommodated within an acceptable length of time.doi:US6128676 AChikatoshi OhkuboUS
