Description
Technical field
The invention belongs to digital processing field, and in particular to a kind of DSP processing systems of piecemeal upgrading.
Background technology
Digital Signal Processing, English original name is digital signal processing, and it is the theory and technology being processed to signal with the mode of numerical computations；The purpose of Digital Signal Processing is that the continuous analog signal of real world is measured or filtered, needed to convert a signal into numeric field before Digital Signal Processing is carried out, generally realized by analog-digital converter, and the output of Digital Signal Processing often will also transform to analog domain, this is realized by digital analog converter.
DSP be widely used to command, control, communications, and information, Signal and Information Processing, automatically control, radar, military affairs, Aero-Space, the system such as medical treatment, these systems are required to it and use function constantly perfect, abundant and upgrade, or make renewal according to the demand of user, most of program maintenance to this kind of terminal device is carried using developer and becomes instrument to by the way of live operation, not only workload is very big, waste time and energy, also it is unfavorable for the unified management and maintenance to whole system simultaneously, there is a problem of certain.
DSP processing systems are typically used for complex signal transacting computing, are solidificated in plate in Flash its program image more, and program is moved in DSP internal memories by Flash and run after upper electricity, data processing and other functions that completion is specified.But, traditional system upgrade is that will again solidify after original program image all erasing mostly, although the method is realized simple, but there is emergency risk, i.e. when system is in accident power-off in updating software process, original normal version program will also be destroyed, cannot run in MCU or DSP, cause system crash；Additionally, the upgrading also having is that two spaces A and B are opened up in the Flash of MCU or DSP, respectively as main BOOT areas and standby BOOT areas, although this method improves the reliability of software upgrading, but increased the complexity of programming or hardware circuit.
The content of the invention
The purpose of the present invention needs the problem for entirely solidifying image again when being and overcoming system upgrade in the prior art.
Therefore, the invention provides a kind of DSP processing systems of piecemeal upgrading, including Flash memory spaces, wherein, the Flash memory spaces include that need to upgrade Flash blocks, application program of reserved block, application program fixes Flash blocks.
A kind of DSP processing systems of above-mentioned piecemeal upgrading, the subprogram data of upgrading are needed in the DSP processing systems can be placed in a function, and the function can be defined into single section.
A kind of DSP processing systems of above-mentioned piecemeal upgrading, the data in described section can be cured to the application program need to upgrade in Flash blocks.
A kind of DSP processing systems of above-mentioned piecemeal upgrading, the reserved block is used to increase the reliability of the DSP processing systems.
Beneficial effects of the present invention：The DSP processing systems of this piecemeal upgrading that the present invention is provided, the block design of Flash blocks is fixed by carrying out to Flash memory spaces need to upgrade Flash blocks, application program of reserved block, application program, needs entirely to wipe original program when solving the problems, such as that whole dsp system is upgraded；The purpose saved the system upgrade time and improve system upgrade reliability is reached；Meanwhile, the erasing times of Flash memory spaces are also reduced, and then improve the service life of Flash memory spaces indirectly；Therefore, the piecemeal upgrading DSP processing systems, only account for sub-fraction for whole system program image, have the advantages that update time it is short, upgrading reliability it is high, have a good application prospect, be worthy to be popularized.
The present invention is described in further details below with reference to drawings and Examples.
Brief description of the drawings
Fig. 1 is the schematic diagram of Flash memory spaces in the DSP processing systems that a kind of piecemeal of the invention is upgraded.
Description of reference numerals：1st, reserved block；2nd, application program need to upgrade Flash blocks；3rd, application program fixes Flash blocks.
Specific embodiment
Technological means and effect that predetermined purpose is taken are reached for the present invention is expanded on further, below in conjunction with drawings and Examples to specific embodiment of the invention, architectural feature and its effect, is described in detail as follows.
As shown in figure 1, in a kind of DSP processing systems of piecemeal upgrading Flash memory spaces schematic diagram, including Flash memory spaces, wherein, Flash memory spaces include that reserved block 1, application program need to upgrade Flash blocks 2, application program fixation Flash blocks 3.
Wherein, the subprogram data of upgrading are needed in the DSP processing systems can be placed in a function, and function can be defined into single section；Data in described section can be cured to application program need to upgrade in Flash blocks 2, and reserved block 1 can increase the reliability of the DSP processing systems.
The DSP processing systems of piecemeal upgrading, change conventional upgrade mode, and the program entirely need not again solidify image, it is only necessary to the part for updating will be needed to be upgraded in program, and remainder then keeps constant；The important strong point of the program is the piecemeal erasing of Flash, that is, wipe the data that a block can be only wiped on the block, the data without influenceing other blocks.Wherein, reserved block 1 can increase the reliability of system, when failure is caused due to frequently upgrading for existing piece, can be solidified in reserved block 1, and the reserved block 1 that the program needs is less；In addition, it needs to be determined that when the part of upgrading is needed in program, because the code and data of DSP are existed in the form of " section " in image file, the part of upgrading can will be needed to be placed in a function in DSP programs, and be defined into one single " section ", by #pragma
CODE_SECTION can realize that this is operated, so as to should " section " Dynamic data exchange out and then to be cured to the single blocks of Flash mono- can be that application program need to upgrade in Flash blocks 2, the Flash blocks 2 that need to upgrade of the application program where upgrade code is only needed to during upgrading are wiped and programming again.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to assert that specific implementation of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, should all be considered as belonging to protection scope of the present invention.
