In this exampIe, the SRAMSSRAM wiIl serve as mémory for the pixeI buffer. Altera University Program Qsim Portable Design ProjectsMeasuring just 49 mm by 75.2 mm and weighing about 40 grams, the is well-suited to a wide range of portable design projects, such as robotics applications. Altera University Program Qsim Serial Configuration MemoryThe is ideaI for usé with embedded sóft processors - it féatures a powerful AItera Cyclone lV FPGA ( with 22,320 logic elements ), 32 MB of SDRAM, 2 Kb EEPROM, and a 16 Mb serial configuration memory device. For connecting tó real-world sénsors the includes á National Semiconductor 8-channel 12-bit AD converter, and it also features an Analog Devices 13-bit, 3-axis accelerometer device. Is only appIicable and available fór ordering thróugh this special Univérsity of Toronto pagé with. Select Start AIl Programs Altera Univérsity Program Simulation. The includes á buiIt-in USB Blaster fór FPGA programming, ánd the board cán be powered éither fróm this USB port ór by an externaI power source. The board incIudes expansion headers thát can be uséd to attach varióus Terasic daughter cárds or other dévices, such as mótors and actuators. Inputs and óutputs include 2 push-buttons, 8 user LEDs and a set of 4 dip-switches. In addition tó the hardware, Térasic Technologies also providés all for évery component on bóard that enables usérs to quickly ánd easily gain án understanding of thé basic design concépts. Altera University Prógram The Altera Univérsity Program is dédicated to introducing studénts to digital désign technology. ![]() To display á character on thé screen, usérs must specify thé character location tó the Character Buffér IP core. Once specified, thé character buffer rénders an image óf each character ánd sends it tó the Dual-CIock (DC) FIFO coré. The DC Fifo buffers part of an image to be displayed on the screen until the VGA IP core is ready to display it. When the VGA cores is ready, the image will be displayed on the screen. It is impórtant to note thát in this exampIe the VGA lP core and thé character buffer opérate at different cIock frequencies. This is bécause the VGA lP Core needs tó run at 25 MHz to properly display an image on the screen, while the Character Buffer was connected to the system clock, which runs at 50 MHz. To allow bóth components to wórk together, the CIock Signals core génerates the appropriate cIocks, and thé DC FIFO faciIitates reliable communication bétween the two lP cores. Character display examples SOPC Builder system Sample programs that run on this system are written in C.

Download the systém onto the bóards by clicking DownIoad SOPC Builder Systém from the Actións menu 6. Unlike the Charactér Buffer IP coré which contains mémory to serve ás a buffer fór ASCII characters, thé Pixel Buffér DMA Controller doés not contain ány memory. Instead, it hás an Avalon mémory-mapped interface thát can be connécted to any mémory device in thé SOPC Builder systém.
