[0005] Since the miniature hard disk was not widely used in the portable electronic product at the beginning, there were few reports on the various tests or performance of the miniature hard disk configured in the portable electronic product. Most of the performance reports are made for the use environment of personal computers. However, the portable electronic product uses the embedded system, and there are many differences between the software and hardware environments between the embedded system and the personal computer. , these differences include hard disk transfer rate, memory, user interface, power requirements, processing core architecture, etc. These differences have a considerable impact on the designers of this portable electronic product when developing new functional applications. Therefore, how to Testing the performance of the miniature hard drive in the operation of the portable electronic product is an urgent and urgent problem to be solved

Embodiment Construction
[0020] A kind of hard disk performance evaluation method of the present invention, please refer to shown in Fig. 1, this method an embedded system carries out access to a hard disk according to a preset condition, then, according to this embedded system reaches this preset condition to read A total access amount and a total read time taken to meet the preset condition are used to calculate an access performance of the embedded hard disk.
[0021] In an embodiment of the present invention, please refer to FIG. 2, the default condition is that the embedded system performs random access to a part of the storage space of the hard disk, and the total access amount is the embedded system's A part of the storage space of the hard disk is randomly accessed for a predetermined number of times, and the total amount of accesses during the predetermined number of reads is used, and the total read time is spent on each of the preset times The sum of a read time, the access performance is t...

The invention discloses a hard disc efficiency evaluation method which is used in efficiency testing of micro hard disc during operating portable electronic products and adopts an embedded system, wherein, the evaluation of the access efficiency of the hard disc set by the embedded system includes the following steps: access of the hard disc is completed according to the preset condition set by the embedded system; a total access amount read and the total read time taken when the embedded system reaches the preset condition is obtained ; by means of the total access amount and the total read time, the access efficiency of the embedded system on the hard disc can be calculated. With the embedded system, the method realizes efficiency testing of micro hard disc during operating portable electronic products.
Description
【Technical field】 [0001] The invention relates to a performance evaluation method, in particular to a hard disk performance evaluation method. 【Background technique】 [0002] Early portable electronic products usually only contain 16MB to 32MB of memory, and it needs to be used for program storage and execution at the same time, and the expansion of the memory of this portable electronic product is not easy, and it is impossible to use a hard disk virtual A memory space is expanded, because most of the portable electronic products do not include hard disks, therefore, the portable electronic products do not adopt the memory management mechanism of the personal computer, so the portable electronic products Dynamic memory configuration must be very careful to avoid insufficient memory, and because the portable electronic product will not automatically reclaim the configured memory when the processing program ends, the application software of the portable electronic product nee...
