容易实现:不需要修改RTL代码,可以通过EDA工具自动插入clock gating。 Clock Gating Efficienccy:有多少时钟周期在通过Clock Gating之后被suppressed。Clock Gating Efficiency = 1 - (TRout/TRin) Register Q-to-CLK ratio:寄存器Q端的toggle与寄存器clk pin的toggle比值。Toggle Q-to-CLK ratio = TRQ/TRclk Clusterin...
While power should be optimized at all stages of the design flow, many times it is only addressed after initial register transfer level (RTL) synthesis runs uncover inefficiencies.Mitch DaleEetimes Com

Several techniques are used for clock gating[1]. The first,combinational clock gating, is a relatively straightforward way of disabling the clock to registers when their output does not change. It involves identifying combinational logic conditions that cause a register to hold its previous value and...
backed up by a few slower cores. A rendering computer will typically benefit from as many cores as possible, and while faster is better, more cores are even better. In mobile environments performance is important but power efficiency is paramount, especially when peak performance is not required...
In this paper, we focus on achieving lower power for existing IPs and the importance of architecture level clock gating and EDA Tool inserted clock gating. Keywords—Low Power, Internet of Things, EDA, Clock Gating I. INTRODUCTION Internet of Things (IoT) is a new era of computing which...
Semiconductor design innovators like AMD want to improve on previous generation designs in terms of faster performance in a given power envelope, higher frequency at a given voltage, and improved power efficiency through clock gating and unit redesign....
This scheme conditionally disables the inverter chain when the input data are kept unchanged, so redundant transitions of delayed clock signals and internal nodes of the latch are all eliminated, leading to low power efficiency. Based on SMIC 65 nm technology, extensive post-layout simulation ...
There is disclosed a method, and associated apparatus, for optimizing a gating expression for controlling the clock gating to a set of clocked state holding elements, said gating expression comprising at least one variable, the method comprising the step of maximizing the conjunctive form of said ...
The clock gating checks often do not get the attention that they deserve early in the design cycle. Most of the EDA tools employed for CTS building deploy the clock gating cells as much close to the root as possible to save on dynamic power. This increases the amount of negative skew and...
