I basically have 3 questions. Are there any groups devoted to homebrewing CPU's and building computers from microprocessor and chip level? I've found a few web sites and threads related to FPGA CPU and building from 7400 level circuitry, but haven't found a web forum or Usenet group yet. I have no desire to build a complete computer, just interested in the basic design and its application...

I'm designing a device that can display high resolution (at least 1080i or 1280x1024) images to a LCD monitor. I don't think that much 2D/3D acceleration is needed for this purpose. Lower hardware cost is the first priority, although ease of development is important too. What is the best route? 1. Microprocessor only, to run embedded Linux and software-based display controller 2. Micr...

I'm looking for an embedded microprocessor that can run a web server. The purpose of it will be to configure an embedded system via a web page similar to how you configure most routers. I've been looking around and have found a few linux ports that run on the Freescale ColdFire microprocessors and the ARM microprocessors however they all are made for specific development boards. (Looked int...

Assume that we have a 16-bit processor which is interfaced to memory of 32-bits wide(word length). The processor has to perform two read/write operations when it wants to read/write data respectively.How does it know the word length of memory it is interfaced to?

Dear all, I am just curious to know why almost all commercial popular RTOS like RTLINUX,Vxworks work mainly on Micro processor instead of Microcontrollers? AFAIK,I have seen Vxworks work on Boards like Intel x86,powerpc,ARM and all mentioned processor boards instead of real microcontrollers like 8051,68HC series from motorola and so. Why do RTOS prefer microprocessors as compared to microco...

Hi, I'am working with a MPC855T PowerPC microprocessor and i try to debug my soft using ICE/BDM. My application raises a "Software Emulation" exception that is catched by emulator and i would like to know which software instruction raised this exception but SRR0 register is 0 (zero). This register should contain the last instruction before exception ? should it not ? Is it possible to ...

Question> Hi, I should make scientific program which use linea alebra with so man matrixs. I would like to know whether it is good to make matrix class using dynami memory allocation (new/delete or malloc/free) or using two-D arrays wit fixed (big enough)size? of course, my focus is efficiency in terms of speed. How much I would experience speed down if I use matrix class using dynami

I am working in interfacing Sitara Processor from texas instruments onto the PCI bus(sitara does not support inbuilt PCI). Can I interface AM3358 with PCI controller like PCI9054. Do I need to add any logic in between Sitara and PCI9054. Please Explain why do i need a logic in between PCI 9054 and processor Regards Viswanath --------------------------------------- Posted through http://w...

Have you already written web applications to render real time data in graphs? The data (relay outputs) are captured by a microprocessor and sent via RS232 to a Raspberry PI running Linux. The data are time stamped (count of milliseconds). The goal is to display the data in a graph with the time as X axis and the relays states as Y axis. There are several relays on a graph. The graph m...

Hi Friends, I was trying to figure out some solution for multiplication of 24bit data with a 24 bit data on 8 bit microprocessor. I got the idea like multiplying first bytes of both data and then the next bytes taking care of carries and finally put it in to 8 bit micro with some adjustment(since a 8 bit micro cannot hold the result of multiplication of 2 24 bit micros). Please correct me...

can anyone explain me to calculate the wait states needed? Suppose we are using 120 nanosecond ROMs, which have valid data on the bus 120 ns after the falling edge on the Output Enable line with a clock rate of 25 MHz (which means a clock cycle of 40 nanoseconds). How many wait states must the microprocessor insert into each bus cycle that reads from the ROM? -----------------...

Hello, First of all, here is a description of the hardware. The microprocessor is a Freescale PowerQuicc8270, connected to a LSI53C1010 controler via a PCI bus, and a hard disk is connected to the SCSI controler. I need to develop a hard disk driver to read and write binary data from/to an offset on the disk. The driver does not need to be generic at all, it should only be able to read/w...

Does anyone know the exact timing of the internal UART on an 8051 based microprocessor (actually it's a Dallas 80C320)? As I understand it, when transmitting, the TI bit sets a the _beginning_ of the stop bit of the byte. So if you wait for the TI bit to go true, and immediately write another byte to SBUF, does this immediately start transmitting the start bit of the new byte, cutting short the st...

What is the differences between: 1.Remapping memories to processor code region and 2.Executing the program code built with absolute addresses without remapping I read something about executing multiple image in a microprocessor (ARM Cortex-M3) and i'm ambiguous about differences between executing with remapping image to "code space" and without remapping? I would be grateful if you help me ...
