Low Power之CPF/UPF

1　　CPF　　

　　The Common Power Format is a standard promoted by the Low Power Coalition at Si2. CPF is also a TCL-based language that operates on speci?cation objects and the design objects. A design object is a module, instance, net, pin or port as they appear in the RTL.

　　The language can be used to express power design intent in terms of:
　　 - Power domains : From physical, logical and analysis point of view
　　 - Power logic : For example, level shifters and isolation logic
　　 - Power mode : State mode table and transitions

2　　UPF

　　The UPF speci?cation is in ASCII format that can be used to specify low power directives that encompass all aspects during the design ?ow. The power speci?cation provided in a UPF ?le can be used by simulation, synthesis, equivalence checking, physical design and physical veri?cation.

tensorfolw配置过程中遇到的一些问题及其解决过程的记录（配置SqueezeDet: Unified, Small, Low Power Fully Convolutional Neural Networks for Real-Time Object Detection for Autonomous Driving）

今天看到一篇关于检测的论文<SqueezeDet: Unified, Small, Low Power Fully Convolutional Neural Networks for Real-Time Object Detection for Autonomous Driving>,论文中的效果还不错,后来查了一下,有一个Tensorflow版本的实现,因此在自己的机器上配置了Tensorflow的环境,然后将其给出的demo跑通了,其中遇到了一些小问题,通过查找网络上的资料解决掉了,在这里

Network management system scheduling for low power and lossy networks

In one embodiment, a network management system (NMS) determines an intent to initialize a request-response exchange with a plurality of clients in a low power and lossy network (LLN). In response, the NMS adaptively schedules corresponding responses

问题描述 stm32f0308正常是运行在Run mode下,这种mode是在reset之后的默认模式.Low Power Mode,即低功耗模式,用于在IC空闲时可以考虑选择进入,使系统耗能降低,在必要的时候通过唤醒在进入Run mode正常工作.Low Power Mode,在嵌入式系统中考虑的很多,也很关键,因为一般都是用移动电源供电,合理使用Low Power Mode,会很好的提高设备的续航能力. Low Power Mode方式 Sleep Mode:CPU时钟关闭,所有periph

Lower Power with CPF(四)

CPF从Front-end到Back-end(RTL--GDSII)的整个流程: 1)Creating a CPF file:来在前端就建立lower power的规范. 2)检查CPF文件的正确性,用形式验证工具检查一些实现上有没有问题,比如missing isolation or level shifter. 3)做RTL verification with cpf:比如在PSO中,需要确认系统可以正确的关闭,再重新start.此时corresponding control signal并不

Lower Power with CPF(三)

常用的一些Lower Power的策略: 1)Clock tree optimization and clock gating:在正常情况下clock信号会一直toggle at the maximum rate and capacitive loads, 所以当在block level引入 clock gating 后,可以极大的减少动态功耗. 2)Operand Isolation:同样,在数据通道(datapath)引入使能信号,在disable的时候,将数据通道的输入force为一个co
