I
BASIC PIPELINE OPERATION
The DSP splits the contents of processing in one cycle to increase the number of pipeline sectors for high-speed
operation. For operations using product adders such as product addition and multiplication, and for operations
using 40-bit adders such as 40-bit addition, the processing latency is two cycles.
I
PRODUCT ADDITION
For product addition and multiplication, the latency is two cycles. Because it is provided with a dual product
adder (MAC) for alternate processing every cycle, however, the DSP can process n successive product addition
(multiplication) steps in (n + 1) cycles.
