BU-65572T Manual 

 

7.7.4  Monitor DMA to Host Buffer 

The 

BU-65572T

  is  fully  compliant  to  the  PCI  standards  for  both  Target 

and Master applications. As a PCI master, the 

BU-65572T

 is capable of 

performing  DMA  block  data  transfers  from  the  monitor  buffers  on  the 
card  to  a  user  buffer  in  the  host  memory.  This  will  allow  the  transfer  of 
data without interrupting the host processor, enabling it to perform other 
more important tasks. 

When  the  application  calls  the  „ddcEnableDma‟  routine,  the  size  of  the 
DMA buffer must be specified. The DMA buffer size must be greater than 
64K  words.  If  it  is  not  greater  than  this  size,  then  the  routine  will  return 
with an error. If the size of the DMA buffer is too large, than the system 
will  not  be  able  to  allocate  it  and  again  the  routine  will  fail.  Since  this 
buffer  is  dynamically  allocated  from  non-swappable  system  resources, 
the  DMA  buffer  size  should  not  be  too  large.  The  buffer  size  can  affect 
system operation if too much memory is requested. 

The  DMA  buffer  is  not  directly  accessible  to  the  application.  All 
operations  that  will  be  performed  on  the  DMA  buffer  must  be  made 
through the appropriate RLT routines.  

7.7.5  Software Control of Bus Configuration 

The 

BU-65572T

  has  the  capability  of  being  connected  to  the  bus  as 

either  Transformer  Coupled  or  Direct  Coupled.  Transformer  coupling 
enables the card to be connected to the 1553 bus with a long stub of up 
to  20  feet.  Direct  coupling  requires  that  the  card  be  connected  to  the 
1553 bus by a stub of no more than 1 foot. The coupling configuration is 
dynamically configurable via functions provided in the „C‟ library. Relays 
on  the  board  are  used  to  select  the  correct  signal  path,  direct  or 
transformer coupled for each of the installed channels. 

This card also has the capability of modifying the bus termination to one 
of  three  different  loads.  If  the  bus  termination  is  set  to  None,  then  the 
effective impedance is infinite ohms. If the bus is set to Full, then the bus 
termination will be 35 ohms. A setting of Half will cause a bus termination 
of 70 ohms. This control makes it quite simple to connect the 

BU-65572T

 

directly to another 1553 device without the need of an external load. As 
with  the  bus  coupling  mode,  the  bus  termination  mode  is  dynamically 
configurable  via  softwar

e  functions  provided  in  the  „C‟  library  which 

control relays for each installed channel.
