processor

问题 Here is the problem I am working on The Problem: A high speed workstation has 64 bit words and 64 bit addresses with address resolution at the byte level. How many words can in be in the address space of the workstation? I defined the different terms in the problem Word Size - Processor natural unit of data. The word size determines the amount of information that can be processed in one go Byte Level Addressing - Hardware architectures that support accessing individual bytes within a word 64

问题 Is it possible to have "32 bit operating system" running on "64 bit processor" ? What happens when I target my runtime in .net to x-64 and my OS is 32 bit ? One more to add "by the way what is meant by 32 bit OS (vs 32 bit processor)" ? 回答1: Yes; the x64 processor is just an extension of x86, which is a 32-bit processor. It will not run. It means the OS contains code for running on a 32-bit processor. 来源： https://stackoverflow.com/questions/9816282/32-bit-operating-system-but-x64-processor

问题 This statement: reg [7:0] register_file [3:0] = 0; Produces this error: Error (10673): SystemVerilog error at simpleprocessor.v(27): assignments to unpacked arrays must be aggregate expressions First of all I am using Verilog, not SystemVerilog, so why is it giving me a SystemVerilog error? Second of all, what is the cause of this error, and how can I fix it? I am using it in my desgin of a very rudementary processor to represent the internal working registers as a multidemmnsional array of

问题 There is an enum of all supported processor architectures here: http://msdn.microsoft.com/en-us/library/system.reflection.processorarchitecture.aspx Is there any way to determine which one corresponds to the running environment? System.Reflection.Assembly.GetExecutingAssembly().ProcessorArchitecture returns MSIL -- obviously wrong. EDIT: Bojan Resnik posted an answer and deleted it. I see that some clarification is needed from the partial trace I got. The assembly needs to run on multiple

问题 Wikipedia says that interrupt flag determines whether or not the CPU will handle maskable hardware interrupts. If the flag is set to 1, maskable hardware interrupts will be handled, If cleared - ignored. I'm having difficulty understanding what is maskable or non-maskable interrupt. What are practical usages of the IF flag? What is maskable/non-maskable interrupt and what's the difference? P.S. I'm just starting to delve into Assembly language and inner workings of the processor, so plain

问题 trying to replace comma between 2 words Durango and PC in the second line by & and then remove the quotes " as well. Same for third line with Orbis and PC I would like to retain the rest of the lines using Python: 2,SIN-Rendering,Core Tech - Rendering,PC,147,Reopened 2,Kenny Chong,Core Tech - Rendering,"Durango, PC",55,Reopened 3,SIN-Audio,AAA - Audio,"Orbis, PC",13,Open ... ... ... Like these, there can be 100 lines in my sample. So the expected output is: 2,SIN-Rendering,Core Tech -

问题 I am reading Network Layer in 'Computer Networking: A top-down approach'. It says, Data plane operates at the nanosecond time scale and is implemented in hardware. Whereas router's control functions operate at the millisecond or second timescale. These control plane functions are implemented in software and execute on the routing processor (typically a traditional CPU). Now my question is about routing processor. Is routing processor (or traditional CPU) a hardware or software? 回答1: Routers

问题 Until now I thought that a 32-bit processor can use 4 GiB of memory because 2 32 is 4 GiB, but this approach means processor have word size = 1 byte . So a process with 32-bit program counter can address 2 32 different memory words and hence we have 4 GiB. But if a processor has word size larger than 1 byte , which is the case with most of processors now days I believe ( My understanding is that word size is equal to the width of data bus, so a processor with 64-bit data bus must have a word

问题 The app I am working on calls upon an external API to process certain requests the user may make. This is of course done in a seprate thread to try and prevent the UI from freezing or slowing down. However, the external API produces it's own mass of threads and does some processor intensive work. As soon as calls are made to it, the CPU usage goes up to 100%. This then locks up my UI. Is there any way in C# of restricting the available CPU usage to a third party API? 回答1: The only thing I can

问题 I used the code from http://www.rgagnon.com/javadetails/java-0580.html to get Motherboard Id, but the result is "null". How can that be? Also I modified the code a bit to look like this to get ProcessorId: "Set objWMIService = GetObject(\"winmgmts:\\\\.\\root\\cimv2\")\n"+ "Set colItems = objWMIService.ExecQuery _ \n"+ " (\"Select * from Win32_Processor\") \n"+ "For Each objItem in colItems \n"+ " Wscript.Echo objItem.ProcessorId \n"+ " exit for ' do the first cpu only! \n"+ "Next \n"; The
