Merged Access; Broadcast Transfer - Analog Devices ADSP-TS101 TigerSHARC Hardware Reference Manual

Merged Access

One type of access to both X and Y register files is the merged access.
Merged access provides efficient data load and store for SIMD applica-
tions, accessing both compute blocks in one cycle.
Merged access splits the data between the two compute blocks. If the data
transfer is specified as a quad-word, two words are transferred to
two are transferred to
, and another is transferred to
CBX
!
The transaction of a normal word to a merged group is illegal.

Broadcast Transfer

For broadcast transfer, the same data is written to
neously. Broadcast duplicates the data from memory to both compute
blocks and can only be used for write-to-compute registers. For more
information refer to the ADSP-TS101 TigerSHARC Processor Programming
Reference.
