I am working on a prototype chip using electron beam lithography near the technique's limits (10 nm wires). I need to bridge from the chip to the PC world and need some embedded hardware. I am a biochemist and programmer (with an MBA, so I am a 'suite' who wants to grab a soldering iron) and while I have studied IC fabrication for a number of years, much of the stuff is still pure voodoo to me. ...

Hi, I'm more of a hardware guy so I'm not sure if I'm using the correct terms.... I have a hardware system build around a microcontroller. The mC is programmed in C, no OS.

Hello All, I am looking for a concept for abstracting of a hardware. It is desired that the concept should be convenient, clear, consistent, logical and pretty universal. My goal is developing more or less universal HAL and application framework for automotive, control and instrumental. It should not be tied to a particular OS, CPU or board. Can you recommend a good reading on tha...

Hello, I'm looking for JPEG image processors (encoders). I found only 2, ADV202 from Analog Devices and PM-36 from Zoran. I would appreciate if anyone could point me to similar devices. It doesn't need to be very fast. I intend to capture one frame of NTSC video with Philips' SAA7111, and then do the conversion to JPEG in hardware, with a dedicated IC. I only need a few frames per second...

For a demo project we want to use a webserver interface to some simple hardware. The initial demo will be 3 devices and after that a very small annular volume. For that reason we don't want to invest too much in hardware/software development and are searching for an off the shelf product. I thought I would find that in a minute, but so far I have been unsuccessfull. What we would like: - M...

Hi - Can anybody tell me for what, if anything, does GCC use the single-precision hardware floating point units on some Cortex-M4 parts? At all? Single-precision float only? Presumably not double? The PIC32MZ EF series parts have hardware double precision; presumably GCC uses this for double? Thanks! Best Regards, Dave

The newer version is the basically the same, but has a maxium max3233e rs232 chip, and a mini headphone jack that we connect to a laptop to program with vendor software via a laptop w/serial port. What would be the easiest way to re...

Hi, I'm exploring tradeoffs in implementation of some computationally expensive routines. The easy (coding) solution is to just use doubles everywhere and *assume* the noise floor is sufficiently far down that the ulp's don't impact the results in any meaningful way. But, that requires either hardware support (FPU) or a library implementation or some "trickery" on my part. Hardware...
