**82258       Advanced Direct Memory Access Coprocessor(ADMA) 01/01/84
***Notes:...
***Info:
Intel's  82258, Advanced Direct  Memory Access  Coprocessor is  a high
performance, 16 bit  DMA processor optimized for the  80286, 80186 and
the  8086 families  of  CPUs and  compatible  with 80386  CPU. It  has
on-chip  bus interface for  the whole  8086 family  architecture. Four
high  speed, independently  programmable  DMA channels  can achieve  a
maximum  cumulative transfer rate  of 8  MByte/sec in  an 8  MHz 80286
system and 4  MByte/sec in 8 MHz 8086/80186 systems.  Channel 3 can be
used   as   a   Multiplexor   channel,   whereby,   it   supports   32
subchannels. This flexibility  allows one to use a  single DMA channel
to   handle  a   large   number   of  slow   and   medium  speed   I/O
devices. Advanced capabilities like  Command and Data chaining and "On
the fly" operations allow the  82258 to remove the I/O management load
from the processor. The 82258  addresses the full 80286 CPU memory (16
MB  for   80286),  thus  simplifying  the   system  design.  Automatic
assembly/disassembly  of data  allows 16  bit processors  to interface
with  common  8  bit   peripherals  and  vice-versa.  Remote  mode  of
operation, where  the 82258 has  its own resident bus,  allows modular
system   design.   The  82258   complements   the  high   performance,
multitasking capabilities of the 80286.
