I have a couple SBC cards from Technologic systems - TS-7200 & TS-7250 - they have PC104 pinouts, the TS-7250 has the pins on the bottom as well as the top. I was thinking of trying to stack them together and see if I can get them to talk to each other via the memory which accesses the PC104 memory. I can't think of any reason not to, other (...)
can we store i mean is there any analog memory also? The only thing that we could barely call as "analog memory" is the switched capacitors on CCD sensors, but it isn't possible to do anything else than serially shift their content.
Hi everyone! I had a semester of embedded systems class where we created and worked with Linux on Zynq7010 SoC. Since I had a Spartan 6 devboard, I wanted to embed a Linux on it. I've created the Microblaze processor in XPS (see attached .mhs file), and made some tests in SDK - Hello World, Peripheral Test, and memory Test - and the were all w
Hy how i make a Sram memory.The block exactly.I must to implement a SRAM-memory 8x8.And i don't know how.How implement the decoder colums,decoder line,buffer....You can help me???Please!!Thx
I'm modeling the following system in MATLAB and plotting the autocorrelation and PSD. I'm getting results that agree with some other simulations, but I'd really like to be able to theoretically arrive at the autocorrelation and PSD functions without needing simulations. I'm an EE grad and have taken a course in stochastic systems but am having a li
iWave systems Technologies recently introduced the iW-RainboW-G15M i.MX6 Q7 module. The new Qseven module features the Freescale 6 Series 1.2GHz ARM Cortex A9 quad/dual/single core processor, on-board eMMC flash, Micro SD slot, expandable DDR3 memory, PCIe Gen2, Gigabit Ethernet, SATA 3.0, HDMI 1.4, SDXC and MIPI CSI/DSI. The Rainbow-G15M-Q7 i
hello, please tell any external memory IC for interfacing with msp430fg4618
My basic question is not something on the difference in memory but the spacing of memory in the processor design. I've seen small scale embedded systems have their ATCM and BTCM placed some distance apart in the address space. Why is it so? And another question is how does Cache and TCM differ physically? And another question is why (...)
Look on Microchip's web site - there are example SD card programs for a variety of PICs. However, I am not sure the smaller PICs are suitable due to limited memory. You need a certain amount on memory to handle the file system (and possibly block read/write). If you ignore standard file systems and simply treat it as a (...)
Each device needs a unique address, perhaps encoded in a "serial memory chip" or "D.I.P. switch." If you perfect this design,
Hello, I'm working as analog designer engineer. For the first time, I'm involved into the design of voltage regulators intended for applications with submicron cmos memories operating at 1.5, 1.8 e 2.5V. My question concern the constraints, from a design point of view, that must be applied to the vdd of the memory systems (FLASH + control logic)
SD card implements various file storage algorithms (FAT, NTFS, etc.). Easiest to learn is FAT (File Allocation Table). You will have to learn how FAT is implemented to store files on memory. You can use this book : "Programming 32-bit Microcontrollers in C - Exploring the PIC32 by Lucio Di Jasio". It gives easy understanding of how FAT works.
Hi all, I'm planning to buy a DSO, mostly for my hobby purposes(private use) and I would be using it for FPGA and microcontroller based projects. I have been doing some market analysis and came to a point where I should choose between two models: 1) TDS-2012C from Tektronix -- TDS2000C
hello everybody i used atmega 8535 and gsm modem that i inserted some numbers through message in atmega. and stored in eeprom via prograamming.and that time and mostly it shows that same number but sometimes it forget these memory that numbers which stored in eeprom. and shows blank and corrupted data. so what is the reason behind that and
To just refresh your memory, it is hard to beat Schaum's outline on feedback and control systems! Also agree, it is hard to knock a classic like Kuo! If you have access to matlab or mathcad, you can fool around with the control systems libraries.
I have special need that requires either some "high-speed" dual ported memory or a way to use bank switching of some static ram between two separate address/data bus systems. I am not finding any high-speed dual-ported memory, and I am having a hard time finding any specialized chip sets that might do the bank switching job. No doubt that is (...)
Hi, Have a look here for info. Embedded systems/memory - Wikibooks, open books for an open world
Kindly rephrase your question as it doesn't mean any thing "How can we used volatile in embedded systems." One should use grammatically correct english as no one has time to break their heads over language of a question!!! "volatile" is an adjaective used for memory like ram which loose its content once power is removed from the system!!!!
Old systems used springs, tape or bucket brigade delay lines. Nowdays I think they are usually digital - digitize the signal, delay it in memory & clock it out through a DAC. Keith
There are plenty of posts at edaboard related to the same topic. Mostly FTDI vinculum and processors with USB host capability, eg. Microchip PIC24FxxGB or Atmel AT90USB1286 or discussed. Microchip has complete example projects for USB memory interface.
