Embodiment Construction

[0026] Programmable chips are different from ordinary integrated circuit chips, which include a variety of modules with different functions, such as multiplexer input and output modules, programmable modules, configuration control modules, and special-purpose modules. The programmable chip only needs to maintain the operation of the multiplexer input and output module, the configuration control module, and the necessary input and output modules to realize simple chip functions. Therefore, according to different applications of the programmable chip, some of the modules can be turned off at some time. In this case, even if some modules that are not used are turned off, the integrity and function of the chip as a whole will not be affected.

[0027] Therefore, the present invention provides a power switching device for a dedicated module inside a chip, which is used to statically or dynamically control the shutdown of non-essential chip internal modules when not in use, and the ...

Abstract

The invention relates to a power change-over switch device of a chip internal special module and a chip. The device comprises a power switch and an isolating unit. The power switch receives a control signal, and switches on or cuts off power input to a chip internal special module according to the control signal. The isolating unit, according to the control signal, outputs the output signal of the chip internal special module when the power switch switches on power input to the chip internal special module, and processes the output signal of the chip internal special module into a digital low-level signal and outputs the digital low-level signal when the power switch cuts off power input to the chip internal special module.

Description

technical field [0001] The invention relates to the technical field of microelectronics, in particular to a power switching device and a chip of a dedicated module inside a chip. Background technique [0002] Field programmable chips usually consist of the following parts, including input and output pins (IO), multiplexers, lookup table logic gates, static memory cell arrays, shift registers, digital signal processors (DSP), embedded Static memory cell array, port physical layer (DDR PHY) of double rate synchronous dynamic random access memory, control logic (DDR CONTROLLER) of double rate synchronous dynamic random access memory (DDR CONTROLLER), port physical layer and control logic (serdes&pcs) of serial converter, As well as configuration modules and specialized modules. [0003] After the field programmable chip is powered on, the above-mentioned modules are all in a power-on state regardless of whether they are working or not, thus resulting in a large static power co...
