This is a technical note on using Analog Devices ADSP-BF538/BF539 Blackfin® Processors, which discusses the methodology for estimating total average power consumption.
This document provides a methodology for estimating the total average power consumption of ADSP-BF538 and ADSP-BF539 Blackfin embedded processors. It is intended to assist board designers in creating power budgets for power supply and thermal relief designs. The analysis covers processors equipped with on-chip flash memory.
ADSP-BF539 includes additional states for the MXVR peripheral, denoted with a trailing '-MXVR' suffix in Table 1.
The value is derived using the IDD-TYP dynamic activity level versus core frequency graph (Figure 1).
It represents peak activity where the core executes 100% dual-MAC instructions fetched from internal memory.
