Abstract

The invention discloses an FPGA unit and an FPGA wakeup method. The FPGA unit comprises a receiving unit used for receiving a wakeup signal of a user and an FPGA used for conducting wakeup according to the wakeup signal. According to the FPGA unit and the FPGA wakeup method, the user-controlled wakeup function is achieved with few logical resources, the user not only can flexibly control FPGA wakeup but also can accurately position a wakeup moment, and the flexibility of the FPGA wakeup is improved.

Description

A kind of fpga unit and fpga awakening method

Technical field

The present invention relates to field programmable gate array (field-programmable gate array, i.e. fpga) neck Domain, more particularly, to a kind of fpga unit and fpga awakening method.

Background technology

With the extensive application of fpga, the motility to fpga awakening method is put forward higher requirement.Traditional fpga Awakening method, realizes inside fpga, carries out fpga wake-up by fpga internal control.Because fpga internal control wakes up the moment Fixing and opaque to user, so user can not flexibly control fpga to wake up, nor carry out accurately determining to waking up the moment Position, constrains the motility of fpga wake-up.

Content of the invention

The present invention provides a kind of fpga unit and fpga awakening method, mainly solves existing fpga and wakes up scheme underaction Problem.

The fpga unit that the present invention provides, comprising:

Receiving unit, for the wake-up signal of receive user；

Fpga, for being waken up according to described wake-up signal.

In certain embodiments, described receiving unit includes: pin group, and described pin group includes at least one fpga pipe Foot.

In certain embodiments, described fpga includes:

User logic unit, for being transferred to wakeup unit by described wake-up signal by interconnector；

Wakeup unit, for waking up to described fpga according to described wake-up signal.

The fpga awakening method that the present invention provides, comprising:

The wake-up signal of receive user；

Fpga wake-up is carried out according to described wake-up signal.

In certain embodiments, carry out fpga wake-up according to described wake-up signal to include:

By the interconnector of the user logic unit in described fpga, described wake-up signal is transferred in described fpga Wakeup unit；

Described wakeup unit wakes up to described fpga according to described wake-up signal.

The present invention provides a kind of new fpga unit and fpga awakening method.Achieve user's control with less logical resource Arousal function processed, user can either flexibly control fpga to wake up it is also possible to be accurately positioned to waking up the moment, improves fpga The motility waking up.

Brief description

Specific embodiment

It should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.

Below by specific embodiment, the present invention is described in more detail.

First embodiment

With reference to Fig. 1, the schematic diagram of the fpga unit that Fig. 1 provides for first embodiment of the invention, this fpga unit mainly wraps Include: receiving unit 11 and fpga 12, wherein,

Receiving unit 11 is used for the wake-up signal (wakeup) of receive user；

Fpga 12 is used for being waken up according to described wake-up signal.

The concrete structure of receiving unit 11 has multiple, as long as enabling above-mentioned corresponding function.In some embodiments In, receiving unit 11 may include that pin group, and described pin group includes at least one fpga pin, the fpga in this pin group Pin can be the general pin of fpga.

Fpga 12 can include user logic unit and wakeup unit, and user logic unit is mainly used in realizing fpga 12 Basic function, the described wake-up signal being additionally operable to receive receiving unit 11 passed by the interconnector of user logic unit It is defeated by wakeup unit；Wakeup unit is mainly used according to described wake-up signal, described fpga being waken up.

The present embodiment is different from traditional fpga and wakes up scheme, wakes up not by fpga internal control, but by user Control, wake-up signal is sent by user, fpga is waken up under the triggering of the wake-up signal that user sends it is achieved that user couple The flexible control that fpga wakes up, improves the motility of fpga wake-up.

Second embodiment

With reference to Fig. 2, the schematic diagram of the fpga unit that Fig. 2 provides for second embodiment of the invention, this fpga unit mainly wraps Include: pin group 21 and fpga 22, pin group 21 includes the general pin of one group of fpga, and fpga 22 includes user logic unit 221 With wakeup unit 222, user logic unit 221 is mainly used in realizing the basic function of fpga22.After electricity on fpga unit, use The wake-up signal that family produces inputs from pin group 21, and pin group 21 connects the user logic unit 221 in fpga 22, and user patrols Pin group 21 and wakeup unit 222 are connected by the interconnector collecting unit 221, and wake-up signal passes through user logic unit 221 Interconnector reaches wakeup unit 222, and fpga is waken up.

The present embodiment make use of the interconnector of user logic unit 221 that wake-up signal is transferred to wakeup unit 222, uses Less logical resource achieves user's control arousal function, and user can either flexibly control fpga to wake up it is also possible to wake-up Moment is accurately positioned, and improves the motility of fpga wake-up.

3rd embodiment

With reference to Fig. 3, the flow chart of the fpga awakening method that Fig. 3 provides for third embodiment of the invention, this fpga wake-up side Method specifically includes that

S401, the wake-up signal of receive user；

S402, fpga wake-up is carried out according to described wake-up signal.

The wake-up signal of pin group receive user can be passed through, described pin group includes at least one fpga in step s401 Pin, the fpga pin in this pin group can be the general pin of fpga.

To can be called out described in step s401 by the interconnector of the user logic unit in fpga in step s402 Awake signal transmission gives the wakeup unit in described fpga；Described wakeup unit is called out to described fpga according to described wake-up signal Wake up.

The present embodiment is different from traditional fpga and wakes up scheme, controls not by fpga device inside and wakes up, but by User's control, sends wake-up signal by user, and fpga is waken up it is achieved that being used under the triggering of the wake-up signal that user sends The flexible control that family wakes up to fpga, improves the motility of fpga wake-up.
