What is the
Resource Manager?
Every VXIbus system must have a module that provides the system’s
resource manager requirements. The resource manager function in modules
with this capability, such as the Command Module, is activated by setting
the logical address to 0.
At power-on, the resource manager function is started. The purpose of the
resource manager is to:
• identify all plug-in modules installed in the C-size mainframe
• set commander/servant hierarchies whereby one or more plug-in
modules control other plug-in modules
• perform A24/A32 address mapping so that modules requiring
additional addressing can receive it
• allocate interrupt lines to manage communication between interrupt
handler modules and interrupter modules
• start system operation
Once the power-on sequence is completed and the system is started, the
resource manager is no longer used.
What are the Slot 0
Functions?
Every VXIbus system must have a module that provides the slot 0
functionality. Modules that have slot 0 functionality include the Agilent
E1406/05 Command Module, Agilent E1482B VXI-MXI Module, Agilent
E1499A Embedded V/382 Controller, Agilent E1497A/E1498A Embedded
V743 Controllers, and the Agilent RADI-EPC7 Embedded Computer. The
module set up as the slot 0 device must then be installed in the mainframe’s
slot 0.
The slot 0 functionality is used during operation for the following purposes:
• locate where modules are installed in the mainframe.
• manage (arbitrate) data flow across the VXIbus backplane busses
• provide the system clock (SYSCLK - 16 MHz)
