功耗估算工具 (PET)
POWEREST
概述
Power Estimation Tool (PET) provides users the ability to gain insight in to the power consumption of select TI processors. The tool includes the ability for the user to choose multiple application scenarios and understand the power consumption as well as how advanced power saving techniques can be applied to further reduce overall power consumption.
PET for AM57x and AM437x Processors:
This downloadable spreadsheet is the mechanism in which users input device parameters needed for their application. Parameters include IP activities/loadings, desired power states, and power management usages. Multiple operating conditions can be applied along with time slots for each state. The power estimation data is embedded in the spreadsheet and generated automatically within the spreadsheet (no upload is required).
PET for AM57x:
PET for AM437x/AMIC120:
PET for OMAP35x, AM35x, AM335x & AMIC110 Processors
The following PET modules are comprised of three steps:
- Download input spreadsheet - This downloadable spreadsheet is the mechanism in which users input device parameters needed for their application. Parameters include IP activities/loadings, desired power states, and power management usages. Multiple operating conditions can be applied along with time slots for each state.
- Upload spreadsheet - Upon completion of the input spreadsheet, users can then upload the spreadsheet to TI for the power consumption analysis. Registration and legal agreement acceptance is required for the upload.
- Power estimation report - This report is emailed to you and contains the information on power consumption based on the spreadsheet that you previously uploaded. The report includes information on leakage, active and total average power, as well as power management voltages, if Smart Reflex is utilized.
Step 1.Download an input spreadsheet and fill it out.

步骤 1.下载并填写输入电子表格。 对于 OMAP35x 处理器: 下载 OMAP35x 的简化电子表格下载 OMAP35x 的高级电子表格 对于 AM35x ARM Cortex™-A8 微处理器: 下载 AM35x 的简化电子表格下载 AM35x 的高级电子表格 对于 AM335x ARM Cortex™-A8 微处理器: 下载 AM335x 的简化电子表格下载 AM335x 的高级电子表格 | 步骤 2.上传电子表格。 | 步骤 3.通过电子邮件向您发送功耗估算报告。 |
PET 使用户能够深入了解所选 Sitara 和 OMAP 处理器的功耗。该工具能让用户选择多种应用方案,并让他们了解功耗以及如何应用高级节能技术以进一步降低整体功耗。
PET 包括三个模块:
- 下载输入电子表格 - 这种可下载的电子表格是一种能够让用户输入其应用所需的器件参数的机制。参数包括 IP 活动/加载、所需电源状态以及电源管理使用。多种操作条件可随时隙一起应用于各种状态。
- 上传电子表格 - 完成输入电子表格之后,用户便可以向 TI 上传电子表格,以便进行功耗分析。上传需要注册和接受法律协议。
- 功耗估算报告 - 包含根据上传的电子表格生成的功耗信息。报告包括信息泄漏、活动功耗、总体平均功耗以及电源管理电压;如果使用了 Smart Reflex,则将通过电子邮件向用户报告。
