Rendition, Inc., was a maker of 3D computer graphics chipsets in the mid to late 1990s. They were known for products such as the Vérité 1000 and Vérité 2x00 and for being one of the first 3D chipset makers to directly work with Quake developer John Carmack to make a hardware-accelerated version of the game (vQuake).
Each DMA channel has a 16-bit address register and a 16-bit count register associated with it. To initiate a data transfer the device driver sets up the DMA channel's address and count registers together with the direction of the data transfer, read or write. It then instructs the DMA hardware to begin the transfer.
In computing, busdma, bus_dma and bus_space is a set of application programming interfaces designed to help make device drivers less dependent on platform-specific code, thereby allowing the host operating system to be more easily ported to new computer hardware.
The IBM PC took a more conventional approach, their adaptor card could support up to four drives; on the PC direct memory access (DMA) to the drives was performed using DMA channel 2 and IRQ 6. The diagram below shows a conventional floppy disk controller which communicates with the CPU via an Industry Standard Architecture (ISA) bus or similar ...
I/O Acceleration Technology (I/OAT) is a DMA engine (an embedded DMA controller) by Intel bundled with high-end server motherboards, that offloads memory copies from the main processor by performing direct memory accesses (DMA). It is typically used for accelerating network traffic, but supports any kind of copy.
Dynamic Microprocessor Associates, Inc. (DMA), was a software company in the United States. Though best known for its remote administration product pcAnywhere , DMA also developed and marketed the relational database management system Formula IV, the BBS software Chairman [ 1 ] and the modem control software ASCOM.

Xeon W-2200 and Core X-Series: Discontinued after April 26, 2024 [2] Cascade Lake is an Intel codename for a 14 nm server, workstation and enthusiast processor generation, launched in April 2019. [ 3 ] [ 4 ] In Intel's process–architecture–optimization model , Cascade Lake is an optimization of Skylake .
In computing, bus mastering is a feature supported by many bus architectures that enables a device connected to the bus to initiate direct memory access (DMA) transactions. It is also referred to as first-party DMA , in contrast with third-party DMA where a system DMA controller actually does the transfer.
