1.4.1 IQEDGE Processing Lanes
In order to improve throughput, the IQEDGE provides two processing lanes. When used with
dual-channel IQ modules, each module is able to process two jobs simultaneously.
The processing lanes are independent of one another, and map directly to the processing
channels of suitable IQ processing modules; so, the IQEDGE lane 1 maps to the module’s
channel 1, and so on.
An IQEDGE processing lane is effectively an SDI daisy chain, connected in ascending slot
number order. Processing jobs requiring the use of multiple modules are handed from one
module to the next along that chain.
Daisy chains are constructed using the
Loop
function. See section 5.5.1 for more information.
Note:
Jobs may cross from one IQEDGE lane to another, but only via IP addressing; this facility
is not available via SDI.
