Low-end Qualcomm Solution - Samsung Galaxy ACE dismantling

The first decision of Samsung Galaxy Ace, its hard work is still a lot of impression, especially after watching Samsung's latest Note4 and Note Edge, there is a feeling of thinking about Samsung. Today, the Galaxy Ace part of the circuit will then understand. In your mobile phone, everyone is most concerned about the processor, which is one of the key factors that measure a mobile phone performance, but for now, the processor's processor has excessive performance, more pay more attention. However, for this Galaxy Ace, it is not a performance of excess performance, but too lack. Samsung Galaxy ACE uses Qualcomm's MSM7227 chipset scheme, WCDMA system, which is an early chipset that has been discontinued. The MSM7227 uses the RISC processor to streamline the design structure, which is a 32-bit processor chipset. Based on the ARM11 architecture, 65nm manufacturing process, the processor is only 600MHz, which is not as good as the current development board. The MSM7227 integrated GPU is Qualcomm Adreno200 with a triangular output rate of 22m / s, and the pixel fill is 133m / s, supports 3D acceleration. The MSM7227 chipset has a 600MHz application processor including a floating point arithmetic unit, 320MHz application DSP, 400MHz modulation demodulation processor, hardware acceleration 3D graphics processor, integrated Bluetooth 2.1 and GPS, 5 megapixel camera, support 30FPS WVGA video encoding, Decodes and display. At present, the MSM7227 device can only upgrade to Android 2.3, which is completely caught in the Android 4.0 or higher. In fact, if you know that the memory of Samsung Galaxy Ace is not surprising, 150MB RAM, in the Android era of the system resource, can 150MB can do. Let's take a look at the radio frequency scheme of Galaxy ACE. RTR6285 includes GMS, WCDMA, GPS transceivers, is the world's most advanced multimode UMTS / EGPRS transceiver, with multi-band UMTS and four-band EGPRS, Roaming. The integrated receiving points on the RTR 6285 transceiver can increase network capacity by 50%, and the average data throughput of HSDPA is 100%, and the system block diagram is as follows. The RF scheme of Samsung Galaxy ACE uses SkyWorks's SKY77554 amplifier and RFMD RF7201 RF front end for 3G and 2G RF scheme, and RF7201 system block diagram is as follows. This time mainly introduces the processor and RF scheme of Samsung Galaxy ACE, which will introduce the composition of other modules on the phone. Bamboo Learn Lei Feng
