hi i have been designing 8086 microprocessor using vhdl. i struct at the designing of instruction Q.plz help me.
Hello: I need help: source code for a microprocessor in vhdl. thanks for your help
I am going to work with parallel architecture and I need to control the development of sources of microprocessor code to choose a subsequent architecture and adapt it to used for own basic processor. that?s why I need an example for code source for microprocessor in vhdl Thanks friendly
Dear all, I m doing a project about 4 bit microprocessor(general purpose)using vhdl. if anybody know some links, informations,books please let me know. i got some problems in 4 bit decoder.and i would like to know the vhdl code for 4 bit decoder. many thanks
design and implementation of 8 bit microprocessor using vhdl and FPGA, CPLD.
i am implementing sap-1 in vhdl.but i cannot make system bus and controller circuit. here is my code of controller.if possible fix the error.i will be very great full library ieee; use ieee.std_logic_1164.all; use ieee.std_logic_arith.all; use ieee.std_logic_unsigned.all; use work.all; entity control_matrix is port( clk :in std_log
I am doing a project of designing a simple function calculator using vhdl. Could anyone lend a helpful hand of suggesting me to related link? And I welcome any opinions regarding to that matter.
Instead of taking ready made code. Better you write ur own. The vhdl codes available for 8085 on net are not up to the mark. They are not written professionally. I wish you write one and post it here. There is gl85 project you can find it on net using google. Some one tried to even write synthesizable gl85. That also you can find on net. Use th

Hello; I will work with parallel architecture, That's why i need to know the development of code sources of microprocessor to choose a subsequent architecture and adapt it to used for own basic processor. That?s why I need an example for code source for microprocessor in vhdl Thanks friendly
Hello all, i'm new in microprocessor world and i want to make my very own project i need to make my very own microprocessor in vhdl and will be using Quartus and implement it on FPGA the question now is what should i start with ? i know that, to make such a good project i need to read about different instruction set architectures (...)
We are trying to make reduced instuction set 8085 microprocessor in vhdl so where we will get information about RISC and internals of 8085? Can anybody tell the Concept in Detail ?
Hello friends.. can you tell me something about designing a up down counter using only half adders (and flip flops) say for 4 bit ? vhdl code would also do ...or a logic diagram or a link....? thanks....
I want to build 4 bit microprocessor in vhdl. Can anybody help in designing the instruction register? The total mnenomics to be constructed are 16. Any help/ any suggesion regarding this topic is welcome. Thank you in advance
i need vhdl code for 8 bit microprocessor,i am getting problem in timing and control unit....and how to synchronize all the components in microprocessor... if any one have please mail ..... thanks
Dear friends, I am doing a project to design 4 bit microprocessor(general purpose). I wonder if I can use 2's instead of 10's for ALU? And if somebody know some books,links,websites, informations... about 4 bit microprocessor design(fully design) and coding of vhdl, pls share me.I would be grateful any (...)
Can anyone help me out .......... i need the vhdl codes for the 16 bit RISC microprocessor.. no pipelining is there ..... it can be the seperate modules data path.. control unit............
i need vhdl code for 8-bit microprocessor
Hi LEON is a synthesisable vhdl model of a 32-bit SPARC* compatible processor, developed by the European Space Agency (ESA) for future space missions. To promote the SPARC architecture and enable development of system-on-a-chip (SOC) devices using SPARC cores, ESA is making the full source code freely available under the GNU LGPL license. LEON
all, I am a newbie when it comes to making a clone of an old 16 bit uP in vhdl. I know there are a lot of gurus around here so here is my question. I am looking for a feedback or hindsight on what to expect when undertaking such a project. Are there any good books written which might help me in tackling this kind of problem? I know that
hi all, I was thinking of designing a 32 bit alu with vhdl.. I have coded with functionalites add,sub,and,or,etc....(no multiplication and divsion).. My doubt is i just wrote case (selectinput) when 001-> c<- a and b; likewise.. is it this much easy to design an alu.. or I am doing something wrong .. pleas advise.. also How would
Does anybody know if there is some vhdl description of some PIC microprocessor?
Hello nice guys, I am looking for vhdl source of the 24-bit counter for MAX3000A. I am a newbie in vhdl and MAX3000A, I just downloaded MAXplus II Basic from Altera web site. I will appreciate any help. visioneer
Hi! Could you help me, please! I need HDLC bit stuffing in vhdl example or link where can I find this. Thanks
well .. i have learnt so as well .. but when i come to design a microprocessor myself .. in a big firm .. i discovered that having a non-8bit register in an 8-bit microprocessor is something normal .. let's say in RISC processors and application specific processors specifically .. for example .. i have designed an FFT/IFFT (...)
Hello all, I want to inplement a 16 bit latch in vhdl with a single reset... I like it to work the same as a RS-Latch, on power up the Q's are set to zero as the inputs go high this is latched across to the respective Q, but if the input that was latched changes back to a zero this will not change the Q that was set. And the single reset line wil
what is the diffirence between bit and std_logic In vhdl?
hi folks i am beginner in vhdl coding. i implemented a 4 bit binary counter using vhdl and downloaded the same in FPGA . The program is not working correctly in FPGA.The count is jumping randomly b/n any value from 0 to 15. The coding is done in behavioural model and the the FPGA used is of xilinx. hope someone could help me
Hi all I designed and implement a 4 bit adder which gets a carrier bit as an input, adds up two 4 bit numbers, and gives a 4 bit number and a carrier bit as outputs in vhdl. What is vhdl code?

Dear, I want to design a 2-bit comparator using vhdl that takes two unsigned std_logic_vectrors A and B and produces bits L,G,E, where L=1 , if AB E=1, if A=B so if one can help me in finding a program for this design, regards
can anyone give me the vhdl code for the 32 bit wallace tree multiplier...
can any body help me........................
What memory and microprocessor? Maybe the processor can access either at byte level or at word level. The A0 can be controlled by some glue logic depending on the access type - byte or word, and of the convention little/big endian. If I remember corectly, for 8086 there were signals like BHE - bus high enable to select word access, lower byte or hi
Hi friends, I am wtiting vhdl code for one application. In that application, Two 8-bit Registers and one 16-bit Counter will be there. The Counter is a DOWN counter. The Register is loaded from external 8-bit Micro Processor(MP) and each Register is referenced with a separate address. When ENABLE (...)
