The wireless telecommunications processor: the operation wireless transceiver system, it can be crossed radio-frequency (RF) transceiver with information exchanges such as phone, note and data and send.Also the signal of the phone that receives from radio-frequency (RF) transceiver, note, data can be transmitted to application processor.
Lcd controller: it is that (dma controller is a kind of unique peripheral hardware at the internal system transferring data to a dma controller, it can be considered as a kind ofly can inside and outside memory and each being had the controller that the peripheral hardware of DMA ability couples together by one group of dedicated bus.Why it belongs to peripheral hardware, is because it is to carry out transmission under the programming Control of processor.It should be noted that and usually only have data traffic large (kBps(transmits the information of what kilobits each second) or higher) peripheral hardware just need to support the DMA ability), responsible view data is sent to LCD display.Because the speed of LCD is lower, and the speed of CPU is higher, if CPU directly sends to view data LCD, can cause the waste of CPU time.Because the speed of lcd controller is very fast, so CPU sends to lcd controller with view data, lcd controller sends the data to LCD again, can save the CPU time.Lcd controller can be supported 8,16, the LCD of MIPI interface (mobile industry processor interface, Mobile Industry Processor Interface).
Multimedia coding-decoder: its inside has that sound is looked, Video Codec, when playing or when recording audio and video, multimedia coding-decoder is decoded or encoded media data.
The RF controller: it is used for controlling radio-frequency (RF) transceiver, in order to convert wired digital signal to wireless communication signal, and sends.Perhaps convert the wireless communication signal that receives to wired digital signal.
MEMORY controller (Memory Controller): MEMORY can be divided into the parts such as RAM, FLASH, SD card.Hard disk on the suitable computer of FLASH, it is used for storage system firmware, user program and data.Dynamic data when RAM is used for the saved system operation.SD card (safe digital card) interface (representing with SD among Fig. 2) can connect T-Flash card (mini SD card), can store user's file, perhaps application program.
The AUDIO controller: the audio frequency input/output interface, can control audio frequency input, output, amplification etc.Support earphone, receiver, hands-free three passages.
I2C controller, SPI controller, KEBORAD controller, MOUSE controller, UART controller: similar with lcd controller, they all are dma controllers, be responsible for the data of CPU are sent to external equipment, perhaps will send to CPU from the data that external equipment receives, use sort controller, can save the CPU time.
In order to make wireless communication module need to support the interfaces such as LCD, SPI, I2C, keyboard, mouse, audio frequency, serial ports, the corresponding interface of the controllers such as LCD, SPI inside the baseband chip, I2C, keyboard, mouse, audio frequency, serial ports need to be connected to corresponding interface.
The software of wireless communication module is divided into boot, application processing function and three parts of Communication processing program, one section start-up code has been solidified in the baseband chip the inside in addition, it is responsible for the boot among the FLASH read out and is put among the RAM, then moves boot.Boot with application processing function and Communication processing program, copies among the RAM from FLASH again.Afterwards, application processing function and Communication processing program are just moved at application processor with above the Communication processor respectively.
Because the software of wireless communication module is divided into three parts, so also want Flash to be divided into Three regions: boot district, application processing function district, wireless telecommunications handling procedure district.Wherein, application processing function can be divided into again kernel, Framework and three parts of file system.
The kernel of Android system is (SuSE) Linux OS, and Linux is a kind of powerful operating system, and it provides the functions such as memory management, file management, management of process.Support application program and driver are dynamically installed unloading.We need to write the driver of the controllers such as LCD, SPI, I2C, keyboard, mouse, audio frequency, serial ports in operating system, to support these general-purpose interfaces.
