Description
Technical field
The invention belongs to integrated circuit logic design field, and present invention relates particularly to a kind of multi bri device controller to add solution
Close dispatch control method.
Background technology
The logic of the data processing of multiple ports is different, using simply clearly switching method, can simplify complex designing
Degree, effectively improve the correctness of logical design.
But in the prior art without a kind of simple clearly switching method of offer simultaneously so that multiple ports are operated in
Under general mode or encryption mode.
The content of the invention
The technical problems to be solved by the invention are for drawbacks described above in the prior art be present, there is provided one kind is in multiport
Multiple ports can be controlled in device controller design while to be operated in general mode (bright logical pattern) or encryption mode (close to lead to
Pattern) under a kind of Curve guide impeller method.
According to the present invention, there is provided a kind of multi bri device controller encryption and decryption dispatch control method, including：Using with
First main interface and the second main interface and first from interface and second from the local bus of interface as device controller and master
Data-routing switch equipment between machine；Moreover, it is respectively configured for the general mode and encryption mode of the configuration of each port
The different bus request routes of data transfer request.
Preferably so that the data transfer request under the general mode of port is only sent out from the first main interface of local bus
Go out, and fixed route to local bus first from interface.
Preferably so that the data transfer request sent from the first main interface of local bus under the encryption mode of port
The second of local bus is routed to from interface by encryption logic；So that under the encryption mode of port from the second of local bus
The data transfer request that main interface is sent is routed to the first of local bus from interface by encryption logic.
Preferably, the transmission path of the data transfer request under the encryption mode of port is designed to so that port adds
Data transfer request under close pattern returns to local bus again after being sent to encrypting module from local bus.
Preferably, the data transfer request under the general mode of port is without encryption logic.
Preferably, the data transfer request for each port of device controller uses different requests number.
Preferably, the transmission path of the data transfer request of different port is changed by the routing policy of local bus.
By the present invention in that by the use of 2 master ports, 2 local bus from port as cross bar switch, cleanly separate
The logical process path of multiple data flows under general mode and encryption mode.Thus, different port cans is operated in simultaneously
Under different patterns.The present invention clearly managed in this way multiple ports of device controller in general mode and
Work under encryption mode.
Brief description of the drawings
With reference to accompanying drawing, and by reference to following detailed description, it will more easily have more complete understanding to the present invention
And be more easily understood its with the advantages of and feature, wherein：
The route that Fig. 1 schematically shows general mode and encryption mode data according to the preferred embodiment of the invention is shown
It is intended to.
Fig. 2 schematically shows the another way of general mode and encryption mode data according to the preferred embodiment of the invention
By schematic diagram.
It should be noted that accompanying drawing is used to illustrate the present invention, it is not intended to limit the present invention.Pay attention to, represent that the accompanying drawing of structure can
It can be not necessarily drawn to scale.Also, in accompanying drawing, same or similar element indicates same or similar label.
Embodiment
In order that present disclosure is more clear and understandable, with reference to specific embodiments and the drawings in the present invention
Appearance is described in detail.
Using with 2 main interfaces (the first main interface m1 and the second main interface m2) and 2, from interface, (first from interface
S1 and second is from interface s2) local bus as the data-routing switch equipment between device controller and main frame.In bus
In logical routing, it can be configured according to different data transfer requests (for example, request number according to data transfer request) different
Routed path.
Preferably, different requests number can be used (with this for the data transfer request of each port of device controller
Distinguishing the data transfer request of different port), and the general mode or encryption mode that are configured according to each port configure
Different bus request routes.
Wherein so that the data transfer request under the general mode of port can only be sent out from the first main interface m1 of local bus
Go out, and fixed route to local bus first from interface s1 (without encryption logic)；So that under the encryption mode of port
The data transfer request sent from the first main interface m1 of local bus be routed to the second of local bus by encryption logic
From interface s2 so that the data transfer request sent from the second main interface m2 of local bus under the encryption mode of port is passed through
Encryption logic is routed to the first of local bus from interface s1.Wherein, the data transfer request under the encryption mode of port is designed
Transmission path so that data transfer request under the encryption mode of port from local bus be sent to encrypting module after return office again
Portion's bus.
Specifically, as shown in drawings, for Fig. 1 as being in two structure chart topologys in Fig. 2, Fig. 1 is more clearly aobvious
Show that the data transfer under general mode only increases the route of a local bus, do not increased excessive logical sum and prolong
When；Fig. 2 more clearly illustrates the route that data under encryption mode have passed through local bus twice.
By the present invention in that by the use of 2 master ports, 2 local bus from port as cross bar switch, cleanly separate
The logical process path of multiple data flows under general mode and encryption mode.Thus, different port cans is operated in simultaneously
Under different patterns.The present invention clearly managed in this way multiple ports of device controller in general mode and
Work under encryption mode.
For example, using having 2 main interfaces and 2 from the AXI (Advanced eXtensible Interface) of interface
In AXI bus logics, different roads is controlled according to different data transfer request identification numbers as data-routing switch for bus
By path.The request of each port uses different identification numbers, the bright logical pattern or close logical pattern configured according to each port
Configure different AXI request routes.
In the specific implementation, the biography of the data transfer request of different port can be changed by the routing policy of local bus
Defeated path.
It should be noted that unless otherwise indicated, otherwise the term in specification " first ", " second ", " the 3rd " etc. are retouched
The each component being used only in differentiation specification, element, step etc. are stated, without being intended to indicate that each component, element, step
Between logical relation or ordinal relation etc..
It is understood that although the present invention is disclosed as above with preferred embodiment, but above-described embodiment and it is not used to
Limit the present invention.For any those skilled in the art, without departing from the scope of the technical proposal of the invention,
Many possible changes and modifications are all made to technical solution of the present invention using the technology contents of the disclosure above, or are revised as
With the equivalent embodiment of change.Therefore, every content without departing from technical solution of the present invention, the technical spirit pair according to the present invention
Any simple modifications, equivalents, and modifications made for any of the above embodiments, still fall within the scope of technical solution of the present invention protection
It is interior.
