Hi, I'm coming from the software part of computing and have very limited experience with the hardware part. When I tried to find the hardware for an embedded system (see below) the cheapest I could find was in the US$ 520 area. Is this the usual range for the described hardware or have I looked at the wrong web sites? power: * minimal power consumption is essential OS / drivers / ...

Hi. The programming interface changed from ISP to PDI on XMega controllers. The JTAG MKII can program and debug the XMegas via PDI with a software update, but only the newer hardware revisions seem to have the required hardware support. I'm not very happy to discard my current hardware and spend 300? for another one. So my question is: What are the hardware differences between the o...

Hi, I am looking for any datasheet or document giving the cache hardware circuit to implement the Least Recently Used algorithm in M-way set associative? I have checked Intel site but can't find any. My expectation is that the hardware will be considerably complex, so do the modern processor (pentium) implement the LRU thanks

Dear All, I am Pavan, from India, really interested in embedded systems. I am a beginner in this field. I ve known that embedded is basically both hardware and Software working in unison and thus completing the system. developing a software can be done using C, C++ and then cross compile into the Microcontroller being used. Now, hardware part is not known to me. 1. how do...

Hi. I want to get my brain around USB interfaces, how to design the hardware and the software, and eventually to find what economic hardware solutions are available, and how USB hardware interfaces can be arranged to make the best use of generic USB drivers to minimise problems associated with driver installation. It's not something that I've been able to investigate in the time-limited pr...

Hi All: I have been involved in coding network layers and higher layers for quite some now. Nowadays in the "ultra low power" scene I am increasingly seeing MAC layers being coded as hardware state machines instead of being in software. The reason given is coding the MAC in hardware makes it "ultra low power" I wonder if any of you know of any comparison or study of hardware vs S/W MACs...

What sorts of hooks can I include in my designs to allow run-time testing of 100BaseTX hardware? Obviously, I can monitor traffic, throughput, CRC errors, etc. to give me a feel for degradation of the overall link. But, what can I do to diagnose things like cabling problems and failures without impacting the quality of the link hardware "otherwise"? (think "built in cable tester") An...

Hi all , Can any one tell me a generic pattern to designing an interface between MCU(Configuring the Hardware ) and FPGA(used as an accelerator). My initial thoughts are to have a dual port RAM implemented in FPGA and accessed as a memory mapped device from the MCU and used to configure the Hardware. Is this viable ? is this the norm? Are there any tutorials on the net that can help(...
