Hi everyone, in the system I am using there is an ADSP21020 connected to an FPGA which is receiving data from a serial port. The FPGA receives the serial bytes and sets an interrupt and a bit in a status register once the byte is ready in the output register (one 'start bit' and one 'stop bit'). The DSP can look at the registers simply reading from a mapped port and we can choose either po...

Hello all, I'm pleased to announce the release of Avalda FPGA Developer v1.0 beta! It enables one to compile regular F# to RTL with parallel programming semantics. Our aim is to help make FPGAs available to a wider group of software programmers who may not have as much experience with HDLs or FPGAs. Please visit Avalda's site to download the beta and check out the blog! cheers, Ste...

I know others here have to deal with long life time support of designs, and I have one where I ahev to also supply the tools (free or paid) so that customer can support in at least 10 years time. The trouble is the design necessitates a PLD/CPLD/FPGA, so the requirements get quite onerous.... Device 100 registers min 50 I/O min Surface mount as TQFP/PQFP/PLCC ...
Persistent stall in the Cypress FX2 FIFO

Hi all, I am using the Cypress FX2 to interface an FPGA to a PC via an USB2.0 link. The FX2 was configured to provide 4 bulk endpoints (+ synchronous FIFOs). Each bulk EP (2,4,6,8) is 512 byte long and is double buffered. All seems to work quite fine, but when a FIFO get full (i.e. the PC send more than 512 bytes) the EP does not take data any more, even if the FPGA empty the FIFO! The end...

Hi, I am currently working on a project where I have to transmit data from a PC to an FPGA board via Ethernet. For that purpose I use the HTG-V4PCIe evaluation board, which is a Xilinx Virtex-4 PCI Express Development Board from HighTech Global (http://www.hitechglobal.com/boards/v4pcie.htm). It features the Marvell Alaska 88E1111 Gigabit-Ethernet PHY which I use in combination with t...

If you reply by email, REMOVE "SPAMNOMORE" in capital letters repeated in my address twice (edit address manually)!!

The task is to boot the Cyclone FPGA from CPU. The standard way for doing that is Jam Bytecode Player available from Altera. It is workable, however for the good variety of reasons, this JBC player is PITA. It seems possible to take the player output as a bit stream, pack it into a binary image and boot the FPGA by bit-banging from this image. The idea looks pretty obvious, and not ...

The Hydra chess computer looks like it is going to be the new world computer chess champion, and it is getting close to being the best chess player, human or computer. What does this have to do with embedded systems? Hydra is FPGA-based, not PC-based - carrying on the tradition of Deep Blue and swinging the pendulum back to hardware. From what I have been able to gather, The Hydra che...

Hi All, I have a FPGA system which requres better than 1pSec jitter. When I ask the Xtal MFG they advise there are 2 methods of measuring Jitter Peak to Peak and an averaging method Measuring the same Xtal the result can be significatly differment values between the 2 methods. Does any one have any information on the 2 methods (or more) how to measure jitter. What would FPGA i...

I hope to get your feedback of what you think of integrating IAR EWARM (probably the same for EWAVR) with the hardware development scene. All our hardware design tools have Tcl scripting support for batching. I think it would be great to have the IAR simulator communicate with our FPGA simulator ( in our case ModelSim ) . This way we can make nightly builds possible and make tests with ...

OV7620 image sensor interface with FPGA headache

Hello, I am trying to use the OV7620 to get a RGB digital output using FPGA Spartan 2 (PEGASUS by Digilent)with the intention to display the image on a regular monitor. The default output of the OV7620 is YCrCb, interlace scan, and 16-bit. While what I need is an RGB, progressive scan, and 8-bit output. I tried so hard to write into the OV7620 register to get the output I want but of no...

Hi, I have my motion control-system setup for a velocity loop. Encoder pulse periods are timed to calculate instaneous frequency and are subtracted from a reference value to form an error signal. The timing and error generation occurs in an FPGA, the control-loop is implemented as a PID in a uC which samples the error register in the FPGA at 100 Hz. My issus is regarding noise: I hav...

Hi, We are evaluating the interface to use for transferring data between an Altera/Xilinx FPGA and CPU. We are considering PCIe and GMII. This is going to be a point-to-point link with bi-directional data transfer hitting 500Mbps. The CPU we are using supports PCIe 1.1. My preference based on the research is to go for PCIe for the following reasons*. - High Throughput * PCIe 1.x at 2....

Hi, Is it feasible, or even possible to implement a complete router on a system on a chip (i.e. on one FPGA)? The FPGA would be one of the higher-end FPGAs that exist. The router should be able to handle BGP and OSPF (i.e. traditional router functionality). For example, which of the following routers would be feasible/possible to implment on a system on a chip (the router should be ab...
