Description
Technical field
The present invention relates to data storage technology, more particularly to one kind realize cache memory (Cache) and
The memory changing method of close coupling memory (TCM, Tightly Coupled Memory) switching at runtime and
Device.
Background technology
In processor architecture, storage system is with different levels, and the nearer memory of the freestone heart, scale is smaller,
Read or write speed is faster.It is most of outside L2 Cache except L1 Cache in existing processor system
Processor system also has L1 TCM；The speed of L1 TCM quickly, what access time was to determine, but generally
Scale is smaller, it is impossible to fully meet actual demand.When the program work or number higher to access speed requirement
According to when L1 TCM are failed to lay down, it is common practice to which being by program or corresponding data definition can Cache
Attribute, in storage to Cache.But, after the time delay disadvantage of this is that Cache by inquiry,
Access time is relatively short if hit, and access time is still very long if not hitting.
The content of the invention
In view of this, the embodiment of the present invention is expected to provide a kind of memory changing method and device, can be effective
Shorten the access time of memory, improve access performance.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：
A kind of memory changing method is the embodiment of the invention provides, including：

Specific embodiment
In the embodiment of the present invention, Cache RAM are first configured to TCM RAM；Judge that what is received asks again
The memory to be accessed is sought, it is raw when the request for the receiving memory to be accessed is Cache RAM
Into the request for accessing Cache RAM；When the request for the receiving type of memory to be accessed is TCM
RAM, generation accesses the request of TCM RAM, is then sent to the access request of generation corresponding
RAM。
Below in conjunction with the accompanying drawings and specific embodiment, the implementation to technical solution of the present invention is made further to retouch in detail
State.Fig. 1 is the memory changing method schematic flow sheet of the embodiment of the present invention one, as shown in figure 1, this implementation
Example memory changing method is comprised the following steps：
Step 101：Cache RAM are configured to TCM RAM；
It is described Cache RAM are configured to TCM RAM to include：Part Cache RAM are configured to
TCM RAM；Or, whole Cache RAM are configured to TCM RAM；In actual applications, may be used
So that according to the actual requirements, part or all of Cache RAM are configured to TCM RAM by selection, for example, working as
System is higher to the rate request of reading and writing data, and the data volume that is related to it is larger when, can be by whole Cache
RAM is configured to TCM RAM；When system is general to the rate request of reading and writing data, and the data volume being related to
When smaller, a part of Cache RAM can be configured to TCM RAM, and determination will according to the actual requirements
It is configured to the Cache address ram scopes of TCM RAM.
Specifically, being configured by the lockdown by way of the Cache RAM for changing, change Cache RAM
Allocation algorithm, the Cache RAM to that will be configured to TCM RAM are not inquired about and are distributed；Will
The Cache RAM for not inquired about and being distributed set up TCM address spaces and TCM RAM one by one
Mapping, TCM RAM are configured to by the Cache RAM.
In the embodiment of the present invention, before Cache RAM are configured into TCM RAM, methods described is also
Including：The data that will be configured in the Cache RAM of TCM RAM are transferred to internal memory.
Step 102：The request memory to be accessed that judgement is received, when the request for receiving to be visited
When the memory asked is Cache RAM, step 103 is performed；When the request for the receiving storage to be accessed
Device type is TCM RAM, performs step 104；
Step 103：Generation accesses the request of Cache RAM；
Step 104：Generation accesses the request of TCM RAM；
In the embodiment of the present invention, because TCM address spaces and TCM RAM map one by one, that is, visit
Ask that TCM RAM, equivalent to 100% hit, therefore, it can directly produce the request for accessing TCM RAM；
And access Cache RAM and then need first to inquire about and whether hit, generated if hit and access Cache RAM
Request go to access corresponding RAM；If do not hit to also need to access next stage storage organization.
Step 105：The access request of generation is sent to corresponding RAM.
In the embodiment of the present invention, after accessing Cache RAM and accessing the request generation of TCM RAM, point
Arbitration process is not carried out, the request after being arbitrated, and it is sent to corresponding RAM.In the embodiment of the present invention,
TCM RAM and Cache RAM can be accessed simultaneously, the access to TCM RAM and Cache RAM
Control process is separate, so as to improve concurrency.TCM RAM and Cache RAM are accessed at the same time
In the case of, TCM RAM and Cache RAM may simultaneously returned data when, accordingly, it would be desirable to simultaneously right
Data are processed, and complete read operation and/or the write operation of data, and returned data and response.
In the embodiment of the present invention, methods described also includes：The TCM RAM are reverted into Cache RAM,
And the data in the TCM RAM are transferred to internal memory.
In the embodiment of the present invention, according to the actual requirements, when system needs TCM RAM, by Cache RAM
When be configured to TCM RAM；When system no longer needs TCM RAM, can be by the TCM RAM
Revert to Cache RAM；When Cache RAM are configured into TCM RAM, can be by Cache RAM
In data transfer (flush) arrive internal memory；When the TCM RAM are reverted into Cache RAM,
Data in TCM RAM can be transferred to internal memory, so as to keep the uniformity of data.
Fig. 2 is the memory changing method schematic flow sheet of the embodiment of the present invention two, as shown in Fig. 2 this implementation
Example memory changing method is comprised the following steps：
Step 201：Close Cache RAM；
Step 202：Data transfer (flush) that the TCM RAM of TCM RAM will be configured to arrive interior
Deposit；
Step 203：The Cache RAM are configured to TCM RAM；
In this step, can select whole Cache RAM or part Cache RAM according to the actual requirements
It is configured to TCM RAM；
Step 204：Open Cache RAM；
In this step, if opening Cache for the first time, then also need to complete the initialization of Cache；
Step 205：Initialization TCM RAM；
In this step, TCM can be filled from internal memory carrying data by DMA；Other can also be used
Initialization mode, however it is not limited to this scope.
Step 206：The request for accessing TCM RAM and Cache RAM is received, is accessed according to the request
Correspondence TCM RAM and Cache RAM；
Specifically, according to the request for receiving, producing the access for accessing TCM RAM and Cache RAM
Request, accesses correspondence TCM RAM and Cache RAM.
Step 207：When TCM need not be used, the data in TCM are transferred to internal memory；
In this step, if also needing to preserve the data in TCM, can be by DMA by TCM
Data its move on to internal memory.
Step 208：The TCM RAM are reverted into Cache RAM.
Step 209：Access Cache RAM.
If it is desired to Cache RAM are configured into TCM RAM again, then step 201 is jumped to.
The embodiment of the present invention, is dynamically used using existing Cache RAM as TCM RAM,
Without newly-increased RAM, think in the situation for not increasing RAM costs, realize TCM RAM and Cache RAM
Between switching at runtime, while access Cache RAM portions and TCM RAM portions, Neng Gouxian
Write and improve data access speed.Because the address of TCM RAM portions is a part for whole address space,
Therefore, memory changing method can also ensure that the uniformity of data described in the embodiment of the present invention.
