Description

Utilize the method for DSP at line writing high capacity or a plurality of FLASH

Technical field

The present invention relates to a kind of DSP (digital signal processor) technology, the online method of firing FLASH of especially a kind of DSP of utilization, specifically a kind of method of utilizing DSP at line writing high capacity or a plurality of FLASH.

Background technology

As everyone knows, after the DSP application system development is finished, generally with the non-volatile low-cost storeies such as FLASH of user program elder generation's programming sheet outside, wait to power on move in the DSP sheet again when resetting or RAM that sheet is outer in full speed running, i.e. bootstrapping loading.

The method of programming FLASH mainly contains the programmable device programming and two kinds of line writings.The programmable device programming needs special programmable device equipment and only is applicable to some pluggable FLASH, and at line writing by means of emulator, by the DSP programming of can programming to the FLASH of any packing forms.Obviously, the latter have save cost of development, reduce device size, the programming flexible characteristic, thereby the application in dsp system is increasingly extensive.

Because under simulation status, be easy to the content in the DSP sheet is write among the outer FLASH of sheet by writing debugging FLASH programming program, so as long as will treat that earlier the content of programming is loaded in the DSP sheet, the FLASH programming program of reruning, can realize FLASH at line writing.

But the internal memory of DSP is limited after all, if user program is excessive, then can only be by the size of buffer memory in the DSP sheet, with the user program paging, then in batches programming to FLASH.In case because of paging causes page number too much, or because of there being a plurality of pagings of a plurality of user program needs, the process of manual control paging programming FLASH will become loaded down with trivial details and very easily make mistakes.

And according to the knowledge of the applicant,, still do not have good solution at present to this.

Summary of the invention

The objective of the invention is very easily to make mistakes at the single mode of programming source file and destination address thereof for the treatment of of manual renewal in the FLASH programming program, the compiling of manual operations FLASH programming program, the also quite loaded down with trivial details problem of process that links, is written into and move, invent and a kind ofly replace manual intervention in the online paging programming of the DSP FLASH process fully with shell script, to eliminate manual errors, what reduce labor intensity utilizes the method for DSP at line writing high capacity or a plurality of FLASH.

Technical scheme of the present invention is:

A kind of method of utilizing DSP at line writing high capacity or a plurality of FLASH is characterized in that it may further comprise the steps:

At first, whether the capacity of judging single FLASH greater than the sheet inner capacities of DSP, if greater than the sheet inner capacities of DSP, then it is carried out paging, makes the sheet inner capacities of the capacity of each paging less than DSP;

Secondly, adopt the mode of conditional assembly to set in advance above-mentioned programming source filename and the destination address thereof all treated;

The 3rd, write GEL batch processing script control FLASH programming program, when writing GEL batch processing script, directly call assembler asm500.exe and linker lnk500.exe in the CCS code Core Generator by a GEL function G EL_System who carries out dos command, carry out the method for asm500.exe by the band parameter and set the correlation parameter option, finish the generation of GEL batch processing script;

At last, load and operation GEL batch processing script, make DSP impose a condition circularly, compile, link, be written into and operation, after last source file is advanced FLASH by programming, stop circulation.

GEL (General Extension Language) is a kind of interpretative code that CCS (Code Composer Studio) provides.Use this language to create the GEL function, can the working environment of CCS be configured, and direct access destination processor (comprise DSP soft/hard emulator).The user can finish robotization batch processing task by writing the GEL script, as compiling, link and working procedure etc.

The mode that the present invention uses conditional assembly instead sets in advance all treats programming source filename and destination address thereof, and write the GEL script and control FLASH programming program, it is imposed a condition circularly, compiles, links, is written into and operation such as operation, advanced FLASH until last source file by programming and stop circulation.As long as correctly be provided with in advance and all treat programming source filename and destination address thereof, whole programming process is finished by the batch processing of GEL script, no longer needs any manual intervention and operation.

Innovation part of the present invention has provided a kind of in the outside method of constantly upgrading compile option automatically of DSP program, in conjunction with the automatic executing function of GEL script, has realized the batch processing of the online paging programming of DSP FLASH.At present, similar bibliographical information does not appear both at home and abroad as yet.

Difficult point of the present invention does not also lie in and writes the GEL script and realized batch facility, but how to set the conditional assembly option of DSP program in the GEL script.Though CCS provides compiling DSP the GEL function G EL_ProjectBuild of item file, this function is not have the ginseng function, so can't the required conditional assembly option of setting program during compiling link DSP program.But, can utilize another to carry out the GEL function G EL_System of dos command, directly call assembler asm500.exe. and linker lnk500.exe in the CCS code Core Generator.By the method for band parameter execution asm500.exe, can set compile option.

Beneficial effect of the present invention:

When the invention solves the online paging programming of DSP FLASH, if divide number of pages too much, the process of the manual control paging programming FLASH difficult problem loaded down with trivial details and that very easily make mistakes that will become.

The present invention replaces manual intervention in the paging programming process fully with shell script, can eliminate manual errors, reduces labor intensity, and enhances productivity, and has broken the technical bottleneck that product can't be produced in batches, and has helped reducing human cost.

Embodiment

The present invention is further illustrated below in conjunction with embodiment.

A kind of method of utilizing DSP at line writing high capacity or a plurality of FLASH, it may further comprise the steps:

At first, whether the capacity of judging single FLASH greater than the sheet inner capacities of DSP, if greater than the sheet inner capacities of DSP, then it is carried out paging, makes the sheet inner capacities of the capacity of each paging less than DSP;

Secondly, adopt the mode of conditional assembly to set in advance above-mentioned programming source filename and the destination address thereof all treated, in the FLASH programming program, the mode of employing conditional assembly sets in advance all treats programming source filename and destination address thereof, and correlative code is as follows:
