Use a pair of NexLink Input and Output blocks to accomplish this Message Too many resources required in the unit _ Too many resources required the units ZZ Explanation The design requires more DSP resources than are available from the Nexia device s specified in the Equipment Table Message Due to insufficient DSP resources all disjoint blocks have been ignored Explanation There are not enough DSP resources available in any Nexia unit in the 153 Nexia Manual LTR system The compiler chose to ignore all blocks which are isolated from any I O blocks and therefore do not affect the rest of the system in any way Message Total maximal duration of delays exceeded in the unit _ Explanation The number of delay blocks and their combined delay ranges exceeds the maximum capability of this unit Currently any single NEXIA unit can provide a maximum of 15 seconds of delay blocks Matrix Mixers with Delay also contribute to this total consuming 1 second per input channel Allocation of DSP blocks to DSPs Message Allocating blocks to DSPs failed to set up a feasible DSP task schedule in the unit Z Explanation Although the total DSP power in the NEXIA unit is sufficient compile was not able to distribute the component objects among the available DSPs When the DSP load approaches 100 it becomes crucial that the objects be distributed more uniformly Try moving certain objects to another unit or replace
