Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the invention pertains. In this embodiment, the related technical terms are as follows:
nfc (near Field communication), near Field communication technology; the wireless communication system is a wireless technology which is initiated by Philips company and is jointly promoted by famous manufacturers such as Nokia and Sony, is integrated and evolved by a non-contact radio frequency identification and interconnection technology, and can be combined with an induction card reader, an induction card and a point-to-point function on a single chip to perform identification and data exchange with compatible equipment in a short distance;
nfcc (near Field Communication controller), a short-range wireless Communication controller;
dh (device host), device host.
Referring to fig. 1, in the prior art, when an NFCC is opened, routing table information is issued under the management of a routing table, and a DH layer executes a routing table write process.
The flow of DH write routing table is as follows:
the NFCC is deactivated.
And writing the routing table information.
The NFCC activation process is performed.
The above DH write routing table flow reads and writes the NFCC.
When NFCC sets up routing table information, routing table management updates the routing table information, and DH layer executes the writing flow of routing table, i.e. the above three steps.
Referring to fig. 2, a processing method for reducing frequent operation NFCC of DH provided in an embodiment of the present invention includes:
s101, constructing a routing table buffer pool in a DH and setting the buffer size.
And S102, writing the routing table issued by the application setting into the routing table buffer pool.
Specifically, the application setting is obtained by inputting an application program loaded by the intelligent terminal through operation of the intelligent terminal, and the set information is sent to the NFCC; the NFCC comprises routing table management, when the NFCC is opened, the routing table management issues a routing table, and a DH writes the routing table into a buffer pool and records the information state of the routing table;
the setting of the buffer size is not limited; wherein the routing table information state comprises: a routing table status flag; 1: to be written, 0: the number of routing tables is the same as the number of completed writes.
Similarly, when the NFCC sets the routing table, the routing table management updates the routing table, and the DH writes the routing table into the buffer pool, and records the information status of the routing table.
S103, when the application frequently updates the routing table, the DH modifies the information in the routing table buffer pool.
Specifically, when the routing table is frequently updated, the routing table is not written into the NFCC immediately, but the routing table is written into the routing table buffer pool through the DH, so that the NFCC is prevented from being read and written each time.
S104, when the preset updating condition is reached, the DH executes the corresponding operation of setting the routing table information; wherein the operation comprises a write routing table information and a write routing table command.
Specifically, the update condition includes that the routing table buffer pool exceeds a set size, a deactivation message is received, and there is a field entry of the NFCC;
when the size of the routing table buffer pool exceeds a set size, the DH executes write routing table information, which specifically includes: deactivating the NFCC, writing a routing table and activating the NFCC; thereby reducing the number of accesses to the NFCC by the DH write routing table.
When the deactivation message is received, firstly checking whether the routing table buffer pool exists, and if so, executing a command of writing the routing table; and if the routing table buffer pool does not exist, executing the general message deactivation process without processing the buffer pool.
When there is a field entry in the NFCC, firstly checking whether the routing table buffer pool exists, and if so, executing the writing of the routing table information; by the arrangement, invalid write-in times of the DH to the NFCC routing table can be completely avoided; and if the routing table buffer pool does not exist, executing a normal flow without processing the buffer pool.
According to the scheme, the routing table buffer pool is added to the DH, so that when the routing table information is set and updated, the routing table information is not written into the NFCC immediately but added into the routing table buffer pool, if the routing table buffer is set to be over-limit, or a deactivation message is received, or when the NFCC enters in a field, the routing table information is set by the DH layer, therefore, the access frequency of the DH writing the routing table to the NFCC can be reduced, and the invalid writing frequency of the DH to the NFCC is greatly reduced when the NFCC does not enter the field.
Further, when applied, the method further comprises: defining the buffer size as n when the buffer size is set, and triggering and generating the deactivation message after the NFCC updates the routing table for n-1 times; thus, the access times of the DH write routing table to the NFCC can be greatly reduced; it should be noted that a single unit of cache size may accept one routing table update.
To facilitate a better understanding of the invention, a specific example is described. If the DH routing table buffer size is set to 10, as shown by the comparison in table 1, the total number of read-write commands for the DH operation NFCC is reduced.

When the NFCC is applied, the updating condition comprises that the routing table buffer pool exceeds the set size, a deactivation message is received, and the NFCC field entry exists;
when the size of the routing table buffer pool exceeds the set size, the DH executes write routing table information, which specifically includes: deactivating the NFCC, writing a routing table and activating the NFCC;
when the deactivation message is received, firstly checking whether the routing table buffer pool exists, and if so, executing a command of writing the routing table;
