Estimating Power for ADSP-SC596/SC598 SHARC+ Processors
An application note providing a methodology and power calculator guide for estimating power consumption in ADSP-SC596 and ADSP-SC598 SHARC+ processors.
Overview
This technical document (EE-440) outlines the methodology for estimating total System-on-Chip (SoC) power consumption for the ADSP-SC596 and ADSP-SC598 SHARC+ processors. It describes the various power domains, including VDD_INT, VDD_EXT, VDD_REF, and VDD_DMC, and explains how to calculate power based on static leakage and dynamic switching components. The note details the use of Activity Scaling Factors (ASF) for the ARM Cortex-A55 and SHARC+ cores to adjust for different instruction execution sequences and workloads. Additionally, it covers power contributions from clock domains (CCLK, DCLK, SYSCLK, SCLK, OCLK), DMA activity, and hardware accelerators to help engineers develop accurate power supply and thermal relief solutions.
Use Cases
- Designing power supply solutions for SHARC+ dual-core DSP systems
- Developing thermal relief and heat dissipation strategies for ADSP-SC59x processors
- Estimating system-level power profiles based on specific software workloads
- Calculating battery life and power budgets for embedded audio and signal processing applications
- Analyzing power consumption across various clock domains and peripheral activity levels
