s3c2410 Timer principle of work_s3c2410, Timer
Monday, December 7th, 2009 at 22:56 | No commentsCategories: Embedded systemShort Content: s3c2410 has provided 5 16 Timer (Timer0~Timer4), Timer0~Timer3 supports Pulse Width Modulation-- PWM (pulse-duration modulation). Timer4 is an internal timer (internal timer), he has not output the pin (output pins). Below is the Timer work schematic diagram.omit image. If the figure above shows, PCLK is the Timer supply oscillator, we through establish each Timer corresponding Prescaler and Clock Divider transform PCLK the input clock signal to transmit for each Timer logical control unit (Control Logic), in fact each ... -
Hypothesized SPI succession in TC77 and in S3C2410 correspondence application_s3c2410, SPI, TC77
Monday, December 7th, 2009 at 06:24 | No commentsCategories: Embedded systemShort Content: 1 introduction Serial auxiliary equipment connection SPI (serial peripheral interface) the bussing technique is one kind of general serial interface which Motorola Corporation promotes. It is one kind of three synchronous bus, the hardware function is very strong. But in digit temperature sensor TC77 and in Tristar S3C2410 processor's correspondence, because receives the data width the limit, uses S3C2410 the existing SPI connection to realize with difficulty, to meet the embedded temperature gathering system's actual function need, designed one ... -

S3C2410 DMA explains in detail_s3c2410, DMA
Sunday, December 6th, 2009 at 14:53 | No commentsCategories: Embedded systemShort Content: The reason that must introduce S3C2410 DMA, because it was too important to the performance! Only then applied flexibly the DMA, CPU performance to be able to come up! S3C2410 has four DMA, each DMA support working basic same, but supports source Dest possibly slightly has the difference, sees Datasheet specifically. Here concrete DMA CONTROL register (DCON) the disposition showed that then draws out DMA each working. Atomic transfer: What refers to ... -
S3C2410 WINCE BSP increase serial port support_s3c2410, BSP, WinCE
Sunday, December 6th, 2009 at 13:01 | No commentsCategories: Embedded systemShort Content: Recently in the evolutionary dragon ST2410 board, generally speaking, good which the superior dragon's board did, the technical support may also ~ However, the superior dragon provides WinCE BSP also is only the few revisions becomes on Tristar's male version BSP, although Tristar S3C2410 can provide 3 UART supports, i.e. each UART controller may work in Interrupt (interrupt) the pattern or DMA (direct memory visit) the pattern, but Tristar provides on male version BSP only increased ... -
The S3C2410 interrupt routine realizes_interruption, s3c2410
Sunday, December 6th, 2009 at 08:04 | No commentsCategories: Embedded systemTags: interruption, S3C2410Short Content: S3C2410 (IRQ) interrupt processing process:omit image. Must pay attention what in this is distinguishes the interrupt and exceptionally approaches the meter to the meter. After the interrupt occurs, always enters from IRQ or the FIQ unusual entrance, then skips to the corresponding exception handler place execution, this exception handler is generally carries on the search interrupt to meter's operation, then transfer interrupt handling routine. The following is the process which the interrupt processing realizes in the application: It ... -
s3c2410 CACHES, WRITE BUFFER explanation_s3c2410, CACHES
Sunday, December 6th, 2009 at 01:14 | No commentsCategories: Embedded systemShort Content: In S3C2410 MMU (memory management unit) explains me to everybody to introduce that MMU the principle of work and part operations has carried on the explanation to s3c2410 the MMU. We knew that the MMU existence the reason is to support the virtual storage technology, but did not know that you have discovered that the virtual storage technology's use can cut overall system's efficiency, because compares with the traditional storage technology, virtual storage technology to memory accessing operation ... -
s3c2410 NandFlash K9F1208U0A/K9F1208U0B read operation_s3c2410, NandFlash, K9F1208U0A, K9F1208U0B
Saturday, December 5th, 2009 at 23:22 | No commentsCategories: Embedded systemShort Content: On what my board uses will be SAMSUNG K9F1208U0B, below I the model NandFlash read will hold the artificial explanation regarding this. First we from the physical structure understood first this chip, the structure drawing as follows showsomit image. Just like hard disk's disk sheet is divided into the track, each track is divided into certain sectors, Nand Flash is divided into together certain Block, each Block is divided into certain Page. By the figure above we may ... -
