DMA (Direct Memory Access) allows hardware devices of different speeds to communicate freely under the underlying embedded framework protocol for CPU. DMA working mechanism: DMA copies the memory data collected by scanning from one address space to another address space. The scanning and transmission action itself is implemented and completed by the DMA controller, and DMA is legally allowed in computer embedded system algorithms. Before purchasing and preparing to use the CapDMA direct memory access device, you should have a preliminary understanding and self judgment of the DMA device, whether it can bring you convenience and entertainment needs in work. Preparation before purchase: This device requires two computers (both desktop and portable), and the recommended host configuration is CPU I5 9400F; Memory DDR4 2133M 16G; 256GB solid-state drive; Graphics card 1060 6G or above, specific configuration depends on your personal needs. Auxiliary unit: CPU I3 4130; DDR3 1333M 8G memory; Solid state 120G; The display output device of the auxiliary unit does not have qualitative requirements. Features: switch, one-click on/off. Customized scheme, high speed solution. DMA requires two computers to operate online. By inserting a DMA access device into the PCIE interface of one device (without running any software), the memory operation data of the DMA access device can be obtained on the other computer Note: The 35T version has better compatibility and the 75T version has better camouflag Some of the accessories are randomly sent from the factory and do not accept the specified, do not affect the use of Colour:Black Material:Plastic Package Contents: 1 x DMA Board 1 x KM Box Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
