M82380規(guī)格書詳情
The M82380 is a multi-function support peripheral that integrates system functions necessary in an i386 processor environment. It has eight channels of high performance 32-bit DMA with the most efficient transfer rates possible on the i386 microprocessor bus. System support peripherals integrated into the M82380 provide Interrupt Control, Timers, Wait State generation, DRAM Refresh Control, and System Reset logic.
The M82380’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.
