Why would you want to connect them to a Spartan 6 FPGA? Wouldn't it be much more convenient to wire them to a microcontroller (or two microcontrollers, if you like the redundance) and control their chip select lines with mcu GPIOs? You can then do with a smaller FPGA for your dsp needs, which will be a far cheaper and easier (...)
HEllo , I am designing a Pure sine wave inverter, Plz suggest me any mcu or dsp which satisfy the following needs 1) Independent pwm, 2) easily available 3) not too much costly 4) simulation software should be easily available
what is your application? you need a PLL that its output follows voltage angle and a Park transform. then determine Iq (which is perpendicular to voltage vector) amplitude according to your demanded power factor. all can be implemented by software in dsp or mcu. Good Luck
Hi! We are currently doing some experiments on LTE by using software defined radio. We write our program in CCS 5 and use the Spectrum Digital emulator to test the program. The boards we are using have already integrated dsp, FPGA, and mcu. We want to send some particular data from eNodeB to UE to test the accuracy of the (...)
Some GPP's/mcu's/dsp's have integrated floating point units as co-processors (for example the: Cortex M4F). Are their any devices that implement floating point as part of the core architecture - and not as an integrated coprocessing unit ?

Hello,all, I want to use a RF modulator which needs four IQ signals(TxBBIN/TxBBIP/TxBBQN/TxBBQP),and I know these BB signals are generally produced by dsp or ARM circuit. My question is that I have only one BB signal from mcu, how can I deal with it and transfer it to four IQ signals? thanks a lot!
I would look at the dspic33f or dspic30f series from Microchip. They are powerful, cheap, fast 16-bit micros with on board dsp engine for heavy duty maths. The development tools are also free downloads. If you go to you will find a lot of information and application notes.
Hi , all I am using ARM cortex-M3 processor .I need to implement bandpass Chebyshev type I filter of certain order and parameters.For that purpose I am trying to use CMSIS-dsp library (APIs).Full detailed description of the API is here :
Which software do you use to design and implement digital filters - any kind of filters (Audio, Images, Video, etc)? I want to do a short survey, so please answer the following: 1- Student/Worker 2- Software tool(s) 3- Hardware target (i.e. mcu dsp, FPGA, etc.) 4- Type of digital filters (FIR/IIR, 1D/2D..., Order, ...) 5- (...)
Hi, guess this was announced today and thought I share this news with the group. ARM keeps up the pressure on all competitors with continuous innovation in the mcu sector. Check out the available information here or check the ARM website. I would be interested what kind of applications the members of this forum
Hi every one ; 1st december I will start a new project about dsp-arm and tft module , but i dont have too much experience , i need some help. first question is , can dsp's drive tft? i mean do i need use arm mcu? second, for 5.5 inch tft, do you have any suggestion (samsung , hitachi....)? third, (...)
Texas Instruments ( ) sells floating point dsp (C67xx family) and Floating-Point digital signal Controllers (TMS320F283xx ) which are a sort of hybrid between dsp and mcu. Also Analog Devices ( ) produces floating point dsp (SHARC and Tiger SHARC families). I don't know if (...)
Hello all, personally I don't think that in the future FPGAs will replace dsps. Modern dsp processors are not designed to do only MAC operations: the border line between GPP/mcu and dsp is not so clear as in the past (just consider TI C6000 family, the DaVinci and OMAP series or Analog (...)
I have searched that material, but I could not find. But that concept is very easy. First you have to sample the wave about 32 or 64 with ADC and OPAMP (Do not use diode rectifier!!!) Second, you may use RMS formula through dsp or high speed mcu. (It is used to floating point math). Third, you need to multiply the value by scale (...)
Hi I have MATLAB with me,A few books about MATLAB and dsp, and some Microchip dspIC controller samples. and ICD2 to programe dspIC. I am reasonabily sound in mcu work,but new to dsp. Any simple projects which I can start with the above (...)
TI has unique dsp processor and popular MSPxx mcu technology for widespread applications such as mobile phone, radar, low-power instruments etc, moreover it extends to analog/RF fields to build its kingdom by merging two advanced chip companies Burr-Brown and Chipcon. In one word, TI possesses leading products in both (...)
Does anyone know of a mcu or dsp that runs as cold as -55C (about -60F), and has an intergrated ADC?
Hi! How can I determine total current consumption of an mcu-dsp etc? I have read from datasheets for dspIC (30MIPS, 16xPLL, 5V, 25degC, PDIP40) that its Idd is 132mA at that conditions and that its maximum consumption current on all ports (from absolute maximum ratings) is 200mA. Is my total consumption current sum of (...)
First of all, do you know what is an embedded system? Embedded systems can be powered by a dsp processor, or a FPGA, thus not necessary restricted to a RISC microprocessor or a microcontroller. and you did not specify what exactly do you want to compare between FPGA, dsp and mcu. Production volume? (...)
:?:could it be done by a 8-bit mcu? ... Almost the CMOS camera module (OV, hynix,...) using I2C interface to transmit bitwise-image information to controller (dsp). External ram, I think, exist for buffering. It may be possible.....but note that the speed of processing and power consumption.:D
Ok people atleast :? talk about some mcu(Microcontroller) or MPU(Microprocessor) or dsp(Digital Signal Processor) you used and felt Good or Bad :roll:
Somebody told me to implement a DVD , need at least 3 Chips one is Servo(the most difficult), the Analog Front end, and (dsp+mcu) What does a dsp CHIP means? What basic function a dsp chip must include ? What different between a dsp chip and a (...)
In the practical application of Viterbi decoder such as wireless communication, the RF part, mcu and dsp comsume more power than the ASIC Viterbi. It is a purly research topic.
Hi I want to use TMS320F2811 ADC to perform FFT in the dsp, but i can not find anythings about the ADC SNR perfromance in the datasheet and user's guides. what is the typical SNR value for such ADCs implemented in dsps or mcus? Regards
Depends on what kind of dsp processing you actually need. For example, many sophisticated DAM (digital answering machine) dsps have 8051-compatible bus for external control. One of our system has 8051 from Atmel as a main control processor and dsp from dspG for phone functions. Ace-X.
Hi 5life, I have a dsp that is booted from a Flash Memory with a fundamental application. The dsp is connected with an SPI-Port to the FPGA (Spartan-IIe) and will load the configuration data from the Flash memory to the FPGA. (You need DIN, DOUT, CCLK and /PROG, where /PROG in my system is connected to the /Reset output.) (...)

We know dsp has fast MAC, BShift, seperate data bus and Program bus, ... which let a processor be a true dsp. But what's let a processor be a mcu? Can any processor support an instruction set be named mcu? and MPU?
You can use FPGAs instead of dsps. But it hard to give you any advice, when you don't describe the task the device should do.
The book "dsp with FPGA" on mcu is scanned and not of good quality
I saw selfwade emulator for TI dsp, if you interested I will try find code + schematics + boards. It can be made < $200

Atmel AVR is one of the most powerful 8-bit mcus. Cygnal and Dallas also makes some quite fast 8051 mcus. If you want an even more powerful mcu you should look for 16- or 32-bit mcus. A very popular and very powerful 32-bit mcu is the ARM core. There is a lot of different (...)
Hi, a simple question about CODE COMPOSER STUDIO, exist a version for the old dsp e.g. the tms320c25? regards gnomix
hi I need some link for give more comment and math formule for anlalyze power line parameter such as (harmonic , Demand , K-Factor, symmetrical .... ) have find C library pack do it ? thanx of help :roll:
