Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
For technical solutions according to the invention are described, describe below by specific embodiment.
Fig. 2 shows the system of selection realization flow of the flush bonding processor start-up mode that the embodiment of the present invention provides, and details are as follows for the method process:
S11, read in the built-in ROM of flush bonding processor flush bonding processor start-up routine to internal memory.
It should be noted that, because the membership that adds of erasable Flash causes flush bonding processor volume to become large, increase cost, and ROM takies small volume, less on the impact of embedded processing volume, so flush bonding processor start-up routine is stored in ROM, more cost-saving than start-up routine corresponding required start-up mode being burned onto to erasable Flash in prior art.
In the present embodiment, start-up routine comprises leader and start-up routine part corresponding to all patterns, leader is used for reading flush bonding processor start-up mode numerical value, decide program corresponding to that start-up mode of carrying out, start-up routine part corresponding to all patterns comprises the program that all patterns are corresponding, different program corresponding to start-up mode.
S12, in internal memory, move described flush bonding processor start-up routine.
It should be noted that, the flush bonding processor start-up routine in this step refers to the leader of start-up routine.
S13, according to non-volatile erasable memory unit address, start-up routine reads the flush bonding processor start-up mode numerical value of non-volatile erasable cell stores;
It should be noted that, non-volatile erasable unit hangs on the address bus of flush bonding processor chip internal, in the time of described chip internal design, can specify a fixed address to this non-volatile erasable unit, just can obtain the data in described unit by described fixed address; Described start-up mode numerical value mark start-up mode, different start-up mode corresponding to numerical value mark, corresponding which kind of start-up mode of concrete start-up mode numerical value, need to determine according to start-up mode numerical value and the start-up mode corresponding relation of start-up routine the inside.
In embodiments of the present invention, the non-volatile erasable storage unit using can support that single is erasable, also can support repeatedly erasable, support repeatedly erasable unit can realize the replacing of start-up mode, in the time that existing start-up mode need to be changed, can be after existing start-up mode start, add the burning step code numerical value in programming non-volatile memory cells again, processor can enter new start-up mode after re-powering startup next time.Support that the erasable unit of single can only be once erasable, be mainly used in product and confirmed to use certain start-up mode to start.
S14, according to described flush bonding processor start-up mode numerical value, start-up mode corresponding to start-up routine search flush bonding processor start-up mode numerical value;
It should be noted that, in this article, flush bonding processor start-up mode is also referred to as start-up mode; In start-up routine, there are flush bonding processor start-up mode and flush bonding processor start-up mode numerical value mapping table, described mapping table comprises start-up mode field and start-up mode numerical value attribute field, according to the described flush bonding processor start-up mode numerical value obtaining, in the start-up mode numerical value attribute field of mapping table, described numerical value is found in search, and by finding the start-up mode that described numerical value is corresponding in relation table.
S15, according to described start-up mode, start-up routine calls program corresponding to described start-up mode and starts flush bonding processor.
Another embodiment of the present invention provides flush bonding processor start-up mode and the flush bonding processor start-up mode numerical value mapping table in the start-up routine of the flush bonding processor that has 16 start-up mode, specific as follows:
As shown in table 1,16 start-up mode only need 4 bit values all to represent.In the application stage of flush bonding processor, user first writes non-volatile erasable storage unit by 4 start-up mode numerical value according to startup demand.
Non-volatile erasable storage unit only needs 4 binary storage spaces, erasable unit compared to existing technology, and the space taking is little a lot, has saved the cost that flush bonding processor is manufactured.By reading in the start-up mode numerical value in non-volatile erasable storage unit, in the start-up mode numerical value attribute field of start-up routine, search described start-up mode numerical value, and find corresponding start-up mode.In start-up mode numerical value mark, 4'b above represents 4 bit.
