Soft-review: the race for survival on the XScale processor

In recent years, programs for overclocking XScale, which are equipped with all the latest Pocket PC platform Pocket PC 2002, the fruit of an unprecedented speed. To date, at our disposal the following tools - Pocket Hack Master, XCPUScalar, Clearspeed, Speedstepper, Turbo Tray and XScaleCtrl. All the above have the same goal, differing only in the ways of achieving it, and, consequently, the results of the work. That's why we decided to find out which ones are of greatest interest. In the superficial study of user feedback it became clear that from this list are especially outstanding Pocket Hack Master, because of its functional completeness and Turbo Tray due to being free, compactness and convenience. About them and talk. Before you do overclock, you need to understand one simple thing: just as in the case of processors for large computer to burn the XScale is very difficult, but lose the information stored in memory, it is elementary. One has only slightly exceeded the frequency, and hard-rezet follow immediately. Therefore, before carrying out experiments on your pocket pet, save a backup copy of data and registry keys on the card. After preliminary training can begin operation. For our tests, we used RoverPC P3, high-speed analog U.S. HP iPAQ 1910. It is for these low-cost but highly-selling machines based on Pocket PC programmers create these tools. In addition, the cost handheld slowest XScale-processor, and their example will increase the speed of demand and particularly noticeable. I must say that during testing because it exceeds the rate in experimental instance had a hard rezet, but the information was restored by the foresight of the stock backup. Backup data, I contrived, thanks to proprietary utilities eBackup, which is located in ROM PDA. Also had to use Resco Registry to create a copy of the registry. I want to warn you that I have, even after a recovery fails to run some programs (such quite a bit, but still), and therefore rely on the backups are not worth it. No effect (a drop screen brightness, hard rezet, unstable work, and so on), pocket computer to run only at 300 MHz. On it I decided to stay. For performance testing I used the programs VOBenchmark 2.12 and PocketMVP.8P with. Avi-files of the following characteristics: resolution - 240x194, the total number of frames - 8365, FPS - 25 Audio Bitrate - 56 kb / s, frequency - 24 kHz, the total length - 0.5:34 min. During the determination of the speed of the PDA for the purity of the experiment, I intend to cut off WisBar and Animated Today, as well as shut down all running programs. The tests were conducted three times, the final result, I took their average. So, let's begin. To begin, define the starting performance of "typewriter" without overclocking.
