In-depth analysis of the new generation of Prima GPS processors

When you are still questioning whether the GPS in your hand is SIRF 3rd or 4th generation, we can only say that those are in the past. The new SIRF Prima era is about to come with the mass production of ACCO's new P series portable car GPS products. Are you ready to welcome this new Prima era? Then please join us in the in-depth analysis of the new generation of SIRF Prima car GPS processors today.

For users, the high-tech built-in chip of GPS products does not seem to be of much concern. What users care most about is whether the GPS product's satellite search and positioning is stable, whether the navigation map is accurate, and whether the surrounding entertainment is practical, which are more in line with the actual needs of users.

Many users are tired of the familiar navigation interface, and hope that the new product can bring them a new navigation experience. In addition, many users have always called the additional entertainment of GPS useless, and the blind superposition of functions has made many additional entertainment flashy and unrealistic. Moreover, the current GPS products are becoming less and less like GPS. So can the arrival of the new SIRF Prima processor effectively improve these current situations? You will find the answer in the following comprehensive test.

As a domestic car brand manufacturer, ACCO's new products have always affected the potential changes in domestic navigation products. The birth of the first domestic manufacturer's independent navigation map reflects ACCO's technical strength in car navigation. With the mass production of ACCO P series, can the popularization of SIRF Prima in the domestic car navigation market once again create a wave in the domestic market? Let's wait and see.

SIRF Prima new generation GPS processor

Let's first take a look at some technical data of SIRF Prima chip, which can also facilitate our reasonable selection for subsequent tests and enhance users' popular understanding of Prima. SIRF Prima chip architecture consists of 10 parts, including ARM11 core processor, 64-channel GPS engine, multimedia decoding encoder, extended storage controller, 2.0 USB, LCD, NAND controller, 2D/3D display speed controller and peripheral device module.

It is worth mentioning that the ARM11 core processor, compared with the 400MHZ SIRF third-generation ARM9 core processor (ARM926EJ), SirfPrima's ARM11 core processor (ARM1136JF-S) has a 600MHZ main frequency, higher frequency, and faster computing speed; and SIRF Prima uses PowerVR MBX 3D graphics ES 1.1, supports 1024×768 resolution and built-in 8GB memory , supports 3D hardware acceleration, can decode MPEG2/MPEG4/H.264/WMV files, and can also smoothly play RM/RMVB format files.

After listing so many tedious data, I believe many users are already a little dazzled. In fact, for SIRF Prima to enter the domestic mass-produced GPS products, we can use Celeron and Pentium processors in CPU to make a more vivid analogy. In addition to bringing us more accurate and stable navigation, the arrival of Prima also makes Prima more advantageous than the original products with rich peripheral expansion functions. So let's take a look at the new era of GPS that Prima brings us.

Smooth 3D navigation becomes a reality

Let's first take a look at the positive performance of SIRF Prima, a new generation of vehicle-mounted GPS processor, in navigation. We selected ACCO's new P series product P600 as the representative product for this Prima analysis. This product has the latest version of Yuanfeng MAP built in as the configuration for navigation maps. The difference from the original Yuanfeng MAP is that the new version of the map incorporates the new 3D real-life navigation and 3D modeled buildings. Although these functions can be realized for the original GPS products, the smoothness and stability of the 3D navigation are difficult to guarantee.

Through the map demonstration screenshots we can see that the 3D version of Yuanfeng MAP built into ACCO P600 is not the so-called three-dimensional map navigation. Users can achieve proportional scaling of 3D real-life maps. In addition, combined with Yuanfeng MAP's new dual-perspective navigation function, users can easily enjoy a new navigation experience in which 3D real scenes and electronic maps coexist. This not only allows users who are new to 3D real-life navigation to gradually adapt, but the dual perspective can also make the 3D real scene effectively compensate for the fuzzy display scale of ordinary electronic navigation maps and the embarrassment of users having no navigation reference, allowing users to navigate more accurately and turn more accurately.

The smooth 3D real-scene navigation and powerful dual-view navigation interface, the mature application of these new navigation functions depends on the powerful computing power of Prima, which is also the incomparable advantage of the ACCO P series in navigation.

Stable actual road test performance

Next, let's take a look at how Prima performs in actual road tests. First, in terms of ACCO P600 startup positioning, SIRF Prima achieved a cold start of less than 40 seconds and a hot start of less than 10 seconds. The first time the aircraft achieved effective positioning, the number of satellites was 7. Judging from the simple startup positioning data, it seems that Prima with a 64-channel GPS engine does not have much advantage. However, we need to remind everyone that the number of effective satellites of the aircraft throughout the road test has always remained above 8, and the product did not lose or drift satellites when passing through deep tunnels and overpasses, so Prima is relatively excellent in terms of positioning stability.

Next, let's take a look at the actual road test experience of 3D real scene. To be honest, before the actual test, we were most worried that the 3D real scene would cause navigation screen delays, thus affecting the normal navigation effect. However, after more than 10 kilometers of city navigation, we found that the 3D real scene navigation of P600 was very smooth. The navigation performance of the body when turning or zooming in the real scene at the intersection was very smooth. The automatic zooming of the 3D navigation map at the intersection with the map scale was also very smooth. Through the actual test, we once again appreciate the smooth navigation experience brought by Pri. Therefore, the cooperation between 3D navigation real scene and Prima is quite harmonious, and users can rest assured in actual application.

High-definition playback without rushing

After experiencing the smooth navigation performance of the Prima, let's take a look at the actual performance of Prima in terms of additional entertainment. For the current domestic car GPS products, ACCO P600 is equipped with a high-definition LCD touch screen with a resolution of 800×480 , and the body memory is standard 128MB. It is particularly noteworthy that the built-in storage space of the body has a capacity of 8GB, which is another advantage of Prima. For GPS that is gradually entering the high-definition era, large-capacity storage space can make the product unique in terms of high definition.

Test video resolution

In order to test Prima's actual performance in high definition, we selected high-resolution pictures and 720P high-definition WMA and RMVB format audio and video for testing. As you can see from our video screenshots, in terms of high-definition video playback and image browsing, smooth video browsing gives P600 a nearly perfect entertainment performance. Compared with the picture delay and playback picture sticking imagination that appear in traditional GPS products, ACCO P600 with built-in Prima does not have these problems. This also reflects from the side that the entertainment function that has been called GPS chicken ribs by many users has completely disappeared in the Prima body. It can be said that through Prima's powerful processing power, audio and video entertainment has been properly performed in GPS, which further strengthens the competitiveness of car-mounted GPS as a portable entertainment electronic product in terms of entertainment functions.

Compared with the image delay and playback image sticking problems that occur in traditional GPS products, the ACCO P600 with built-in Prima does not have these problems. This also indirectly reflects that the entertainment function, which has been regarded as useless by many users, has completely disappeared in the Prima body. It can be said that through the powerful processing ability of Prima, audio and video entertainment has been given due performance in GPS. This indirectly further strengthens the competitiveness of the car GPS as a portable entertainment electronic product in terms of entertainment functions.

Open the belly and hit Prima

If all the relevant functional tests are just empty talk, then let's take a look at the intrinsic quality of the new generation of GPS represented by the legendary Prima through the real disassembly of ACCO P600. We can also take a look at the performance of the hardware workmanship of ACCO's car GPS product, which is the first in China to implant Prima.

By disassembling ACCO P600, we can see the excellent manufacturing process of domestic brand GPS products, full wave solder joints, neat wiring workmanship and high-quality connector selection. We can see that ACCO is meticulous in hardware workmanship. In addition, the whole machine has 5 metal shielding covers of different sizes to ensure more stable positioning of the body, and can effectively prevent various electromagnetic interference in the car and complex use environment.

Conclusion:

With the new 3D real-life navigation and the smooth navigation performance of P600, we no longer have to doubt the stability of Prima. With the perfect browsing of high-resolution pictures and the smooth playback of 720P high-definition videos, we no longer have to doubt the expansion of Prima in entertainment. Through our comprehensive actual tests, SIRF Prima can fully meet the actual needs of users, and compared with the original products, it has made great progress in both navigation quality and entertainment performance. It seems that a Prima revolution is coming.

At the same time, we need to note that ACCO's rigorous manufacturing process has also played an important role in the popularization of SIRF Prima. This is also the reason why Prima has gained stability in mass production and popularization. Finally, we would like to thank ACCO for providing us with this test sample. We hope that their new P series products equipped with SIRF Prima will achieve excellent performance in the domestic car navigation market.
