82380
High Performance 32-Bit DMA Controller
The 82380 is a multi-function support peripheral that integrates system functions necessary in an
80386 environment. It has eight channels of high performance 32-bit DMA with the most efficient
transfer rates possible on the 80386 bus. System support peripherals integrated into the 82380
provide Interrupt Control, Timers, Wait State generation, DRAM Refresh Control, and System Reset
logic.
The 82380’s DMA Controller can transfer data between devices of different data path widths using a
single channel. Each DMA channel operates independently in any of several modes. Each channel
has a temporary data storage register for handling non-aligned data without the need for external
alignment logic.
