Embodiment Construction

[0051] The present invention is described in detail below in conjunction with accompanying drawing:

[0052] (1) Design floorplans with different Cache / SPM capacity ratios.

[0053] It can be seen from the formula (2) that the real-time temperature control of the corresponding components can be achieved by changing the power consumption P or the thermal resistance R of the components. Both thermal resistance and thermal capacity are related to the area of ​​the component, while the area of ​​the cache and SPM is determined by its capacity and manufacturing process. At the same time, the power consumption of the storage components cache and SPM is also mainly determined by their capacity and manufacturing process. It can be seen that, in the case of the same manufacturing process, the capacities of the storage components cache and SPM are the determining factors of their temperatures. Therefore, in the system design stage, the present invention changes the capacity ratio of S...

Abstract

The invention discloses a temperature-sensitive mixed storage framework and a data distribution strategy of the temperature-sensitive mixed storage framework. The method comprises the following steps: (1) according to a storage component cache and an area model of a (scratch pad memory) SPM, designing floorplans with different cache / SPM capacity ratios; (2) according to a temperature model of an embedded processor, working out cache / SPM usage time t1 / t2 ratios in storage system temperature changing periods aiming at different cache / SPM capacity ratios, choosing a floorplan with the maximal t1 / t2 ratio as a designing scheme; (3) according to the designing scheme obtained from the step (2), designing the data distribution strategy; and under the condition of limiting peak temperature, using a greedy algorithm to achieve the data distributed to the cache or the SPM to obtain shortest data access time.

Description

technical field [0001] The invention belongs to the field of embedded real-time systems, and in particular relates to the design of a hybrid storage architecture based on high-speed cache and SPM (Scratchpad memory), and a corresponding temperature-sensitive data distribution strategy. Background technique [0002] In recent years, with the rapid development of semiconductor technology, the performance of embedded systems has been greatly improved. However, the development of semiconductor technology has brought about high power consumption density and high temperature while improving chip integration. Statistics show that the power consumption density of processors will double about every three years. Excessive power consumption density will lead to a sharp increase in the heat generation inside the chip, and the temperature inside the chip will also rise accordingly. High temperature has negative effects on embedded systems in various aspects: high temperature will reduce...
