technical field

The invention belongs to the field of semiconductors, in particular to an intelligent terminal chip.

Background technique

Smart terminal chips (such as mobile terminal chips, tablet computer chips, etc., also known as system-on-chip) have strict requirements on performance and power consumption, so in various forms of smart terminal chip products, a variety of low Power consumption power management technology, adaptive voltage scaling (AdaptiveVoltageScaling, AVS) is one of them, AVS fine-tunes the voltage of the component according to the input monitoring data, so that it is in a reasonable range, so as to reduce power consumption while to meet performance requirements. The timing sensor (TimingSensor, TS) that provides input monitoring data to AVS is the timing sensor (TimingSensor, TS). TS uses hardware to monitor certain parameters inside the System-on-Chip (SoC), and then calculates these parameters to obtain The monitoring data is then fed back to the system, which activates the Adaptive Voltage Scaling (AVS) component to adjust the operating voltage of the chip. It should be noted that the above-mentioned TS is used to monitor parameters that have an impact on timing, such as process, voltage, temperature, etc., and the above-mentioned components can specifically be: a physical module in the chip, such as a central processing unit (Central Processing Unit, CPU) or memory control Device (SDRAMController), etc.

In realizing the technical solution of the prior art, it is found that the prior art has the following technical problems:

The application mode of the TS used in the prior art is relatively single. Generally, only one TS is set for a component to monitor the parameters, resulting in insufficient comprehensive and inaccurate monitoring of the parameters, so that the AVS fails to achieve the expected purpose and the purpose of reducing power consumption. .

Contents of the invention

The purpose of the present invention is to provide an intelligent terminal chip, aiming at solving the problem that the purpose of reducing power consumption cannot be achieved in the prior art.

The present invention is realized in this way, an intelligent terminal chip, the intelligent terminal chip includes: a plurality of components, and the components include: a plurality of regions;

The chip also includes:

A plurality of first timing sensors TS are used to sample the monitoring parameters in the plurality of regions, and calculate the sampled monitoring parameters in the plurality of regions through the internal algorithm of the first TS to obtain the monitoring parameters in the plurality of regions the first monitoring data;

The multiple second TSs are used to sample the monitoring parameters of the multiple regional power sources, and calculate the sampled monitoring parameters of the multiple regional power sources through the internal algorithm of the second TS to obtain the second TS of the multiple regional power sources. Monitoring data; the monitoring parameters include: the process in the area, the voltage in the area and the temperature in the area;

An arithmetic unit, configured to perform arithmetic processing on the first monitoring data and the second monitoring data through a specific algorithm in the chip to obtain processed monitoring data;

In the technical solution of the present invention, multiple areas are set in multiple components of the smart terminal chip, and multiple first TSs and second TSs are set, wherein the first TS samples monitoring parameters in multiple areas and obtains the second TS through calculation. One monitoring data, the second TS samples the monitoring parameters of multiple regional power supplies and obtains the second monitoring data through calculation, and the operation unit applies the specific algorithm in the chip to process the first monitoring data and the second monitoring data to obtain the processed monitoring data For the power management controller, the power management controller adjusts the working voltage of the chip according to the processed monitoring data. Since the power supply in multiple areas rarely interferes, the monitoring parameters in the area will be interfered by the same power supply in the surrounding areas, so after setting the first TS and the second TS, the monitoring parameters sampled by the second TS are close to the theoretical values of the area monitoring parameters , calculate that the second monitoring data is close to the theoretical value of the area monitoring data, the monitoring parameters sampled by the first TS can reflect the influence of different area power sources to the first monitoring data, so the first monitoring data is close to the actual value of the area monitoring data, Considering the first monitoring data and the second monitoring data comprehensively, the sampling parameters and monitoring data can reflect the timing information of the current area more comprehensively and truly. Accurate timing information means precise voltage configuration, that is, it can accurately compress the voltage safety margin , compressing the safety margin of the voltage can reduce power consumption, so that the operating voltage of the chip can be adjusted more reasonably, so it has the advantage of reducing power consumption.

It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The specific embodiment of the present invention provides an intelligent terminal chip. As shown in FIG. 1 , the intelligent terminal chip includes: a plurality of components 11, and the component 11 includes: a plurality of regions 111;

The above chips may also include:

A plurality of first timing sensors TS112 are used to sample the monitoring parameters in the multiple areas 111, and calculate the monitoring parameters through the internal algorithm of the first TS112 to obtain the first monitoring data in the multiple areas 111;

A plurality of second TS113s are used to sample monitoring parameters of power supplies in multiple regions 111, and calculate the monitoring parameters through an internal algorithm of the second TS113 to obtain second monitoring data of power supplies in multiple regions 111;

An arithmetic unit 12, configured to perform arithmetic processing on the first monitoring data and the second monitoring data through a specific algorithm in the chip to obtain processed monitoring data;

The power management controller 13 is configured to adjust the working voltage of the smart terminal chip according to the processed monitoring data.

In the technical solution provided by the present invention, after the first TS and the second TS are set, the monitoring parameters sampled by the second TS are close to the theoretical value of the area monitoring parameter, the calculated second monitoring data is close to the theoretical value of the area, and the monitoring parameters sampled by the first TS are close to the theoretical value of the area monitoring parameter. Parameters can reflect the influence of power supplies in different areas to the first monitoring data, so the first monitoring data is close to the actual value of the area monitoring parameters, comprehensively considering the first monitoring data and the second monitoring data, so that the sampling parameters can be more comprehensive and true The timing information of the current area can adjust the operating voltage of the chip more reasonably, so it has the advantage of reducing power consumption.

It should be noted that the above-mentioned monitoring parameters and monitoring data are two different values, and the monitoring parameters may specifically be: the voltage in the area, the temperature in the area, and the process in the area, monitoring data (including the first monitoring data and the second monitoring data) Monitoring data) is the TS output value obtained by TS calculating the above monitoring parameters through an internal algorithm.

It should be noted that, the specific division method of the above-mentioned multiple areas can be assigned by the manufacturer based on experience, and the specific embodiment of the present invention does not limit the specific division mode of the areas. In addition, the above-mentioned multiple areas belong to logical areas. The above-mentioned specific algorithm can be processed by a variety of existing algorithms, such as the average algorithm, the maximum value algorithm or the minimum value algorithm. Of course, it can also be processed by other algorithms. The specific specific algorithm is provided by the chip supplier. , but the manufacturer can choose the specific algorithm above. Let’s take a practical example to illustrate how to obtain the processed monitoring data. Here, the average algorithm is used as an example. Assume that there are three first monitoring data calculated by multiple first TSs, named respectively as data 1, data 2 and Data 3, there are 3 second monitoring data calculated by the second TS, respectively named as data 4, data 5 and data 6, then the processed monitoring data is: (data 1+data 2+data 3+data 4 +Data 5+Data 6)/6. In addition, the above-mentioned multiple regional power sources may specifically be: a power layer of a chip that supplies power to the region. In addition, the power management control 13 can adjust the working voltage of the smart terminal chip by adopting methods in the prior art, for example, using AVS technology to adjust the working voltage of the smart terminal chip.

Optionally, the above-mentioned multiple first TS112 are specifically used to obtain multiple monitoring parameters in multiple areas by sampling multiple times before and after the sampling time, and pass the multiple monitoring parameters in the multiple areas sampled through the first An internal algorithm of the TS calculates and obtains the first monitoring data in the plurality of areas;

The multiple second TS 113 above are specifically used to obtain multiple monitoring parameters in multiple areas by multiple sampling at multiple times before and after the sampling time, and pass the multiple monitoring parameters in multiple areas sampled through the internal of the second TS The algorithm calculates and obtains the second monitoring data in multiple areas.

The present invention uses the above method to eliminate the influence of accidental factors on the sampling monitoring data, because the problem of inaccurate monitoring parameters may occur only when sampling monitoring parameters at the sampling time, because if there is sudden interference at the sampling time, the sampling monitoring parameters will have It may be inaccurate due to sudden interference. We sample multiple monitoring parameters at multiple time points before and after the sampling time, and then use the above-mentioned specific algorithm to process multiple monitoring parameters, so that the impact of sudden interference on monitoring parameters can be reduced. , so it has the advantage of further reducing power consumption.
