SDRAM connection VHDL design_SDRAM, VHDL
Sunday, January 10th, 2010 at 03:01 | No commentsCategories: EDA/PLDShort Content: SDRAM connection VHDL design RAM (random access memory? Is one kind applies widely in the electronic system? , usually uses in the data and the procedure buffer. Along with the semiconductor industry's development, RAM has obtained the rapid development, from RAM, DRAM (Dynamic RAM, namely dynamic RAM) develops SDRAM (Synchronous Dynamic RAM, namely synchronized dynamic RAM), the RAM capacity is getting bigger and bigger, the speed to be getting higher and higher, may say that memory's capacity ... -
Cyclone II DDR the SDRAM connection realizes_SDRAM, DDR, Cyclone
Thursday, December 17th, 2009 at 14:15 | No commentsCategories: EDA/PLDShort Content: In does not increase the circuit wafer order of complexity in the situation, if wants to strengthen the system performance, improves the data bit wide is an effective method. Usually, may expand the system frequency a time or doubles the data I/O base pin realizes the double data bit wide. These two methods are we did not hope that uses, because they will increase the entire design system's order of complexity. In the total data I/O base pin ... -
Outside DSP piece high speed magnanimous SDRAM memory system design_DSP, SDRAM
Saturday, November 21st, 2009 at 10:17 | No commentsCategories: Embedded systemShort Content: Abstract: Introduction use synchronization dynamic RAM(SDRAM) expands the embedded DSP system high speed ultra large capacity exterior storage space the design method; The union has succeeded realizes, based on the TMS320C6201 digital signal processing system, the elaboration uses IS42S16400 the SDRAM chip to design outside the DSP piece the synchronization memory system to realize the plan specifically; Discusses TMS320c6201 EMI and the SDRAM connection design and the programming method in detail. In digital image processing, the aerospace and ... -
The S3C2440 application writes down_S3C2440, FLASH, SDRAM
Friday, October 16th, 2009 at 13:16 | No commentsCategories: Embedded systemShort Content: The time passes really quickly, was engaged in the ARM aspect in a moment the hardware development work already more than one year, since this for more than year in has used SAMSUNG S3C2440 to carry on the product development, in the performance history little attainment realizes writes down, by for everybody reference, not the correct place asked everybody to point out mistakes. I believed that is technical everybody to exchange, resources multi-sharing, certainly, in has not divulged ... -
Solves TMS320C54x and the SDRAM connection question using FPGA
Thursday, November 20th, 2008 at 16:12 | No commentsCategories: EDA/PLDShort Content: In the DSP application system, needs outside to expand memory's situation massively to meet frequently. For example, in digital camera and camera, for gets down scene photography's many pictures or the image interim, after needs to shift the DSP processing data after the external memory in prepares uses. Looking from the present memory market, SDRAM as a result of its performance price ratio superiority, but is favored by the DSP exploiter. DSP and the SDRAM direct connection is impossible. ... -
Isolates equipment’s design based on the GAP technology’s network
Wednesday, October 29th, 2008 at 00:17 | No commentsCategories: EDA/PLDShort Content: Abstract: Introduced briefly the GAP technology the principle, proposed one kind realizes the plan based on scene programmable gate array (FPGA). Through the multianalysis SCSI agreement controller's design and SDRAM the IP nucleus's application, the SCSI agreement controller, the SDRAM controller and the core controller integration realizes in FPGA. After the test, this kind of plan has a higher reliability and the compatibility compared to the MCU SCSI agreement controller's plan.Key word: FPGA; SCSI agreement controller; GAP 1 introduction Along ... -
Outside the DSP piece the high speed sea sets at SDRAM the memory system design

With realizes - en.51rd.net based on the SDRAM video frequency processor design
Monday, October 20th, 2008 at 07:57 | No commentsCategories: StorageShort Content: Introduction In the information processing, specially in real-time video image processing, usually must to realize the video image to carry on processing, but this must first design the large capacity memory, although synchronized dynamic random-access memory SDRAM has the low in price, the capacity in a big way and so on merits, but because the SDRAM control structure is complex, the commonly used method designs the SDRAM universal controller, this causes many people to be able not but ... -
In DSP memory sharing and fast access technical design
Tuesday, October 7th, 2008 at 07:55 | No commentsCategories: DSPShort Content: Abstract: Introduced between many DSP or DSP with other CPU between the memory sharing technology's basic design method, introduced with emphasis how to raise memory's access speed in the design and overcome the visit competition the method. 2 DDRSDRAM high speed sharing visits In the above way, if at the same time 2 piece of DSP must carry on visit to the shared buffer memory, its access speed will reduce one time. In actual signal processing system, specially in continual video signal ...
