Under computer architecture course, I've to design a microprocessor with 8 bit data and 16 bit address ..minium 20 instructions and at least 2 mode to address. I need to write RTL for instructions and there timing diagrams and block diagram of the circuit.
Is there any software which helps to write RTL (...)

see you will find 8-bit 8051 mcu (along with other processors, specially OPENRISC docs are very readable despite it is 32-bit ) and associated docs...
see also for 16-bit RISC paper.
see also xilinx picoblaze docs (and core as well)
vhdl books also contain processor design as well:

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 ..like data path.. control unit............

Depends on the language you are using and where you check the 1, 3, 5.
Suppose you are sending 4-bit BCD to a 7-segment decoder. Run the 4 bits to 4 input ports on a microprocessor.
Then read the four bits into a nibble (a 4-bit data type in some languages), say you store it in a variable called number... (...)

I had written a vhdl code for 16 bit microprocessor and i would like to implement this on CPLD. And i would like to know can i made my own PCB or i have to purchase the ready-made board. If it is possible what are the necessary interfacing devices.

I am trying to implement a DDS on a FPGA and I need a serial interface to program the registers associated with it.
For example the incremental phase and the start phase may take 2 x 48 bit registers or 12 x 8 bit registers. A second DDS will have more registers.
I found several vhdl implementations of SPI slaves. But they seem to (...)

I didn't learn vhdl from a book. In my daily work I'm sometimes reviewing IEEE 1076.
From the books I have seen, I like Enoch O. Hwang, Digital Logic and microprocessor Design With vhdl, but I'm sure there are many other good ones.

As far as I know, MicroBlaze IDE is part of Xilinx's EDK (Embedded Development Kit). It is an all-in-one package for designing embedded programmable systems based on Xilinx's own 32-bit microprocessor core that is called MicroBlaze.
If you're a beginner as you said you probably want to start with a simpler general HDL design (either (...)

I want to make a compiler for a microprocessor I am doing in vhdl, a have the instruction set a I just want that the compiler take a txt file with the program , and give an another txt file with machine code. I think visual basic can make the interface part but it also can do the scaner part of the txt file and parser(do the grammar part) to

well you have written a very high level code, thats way its taking time. ireg is written in very high-level description, that might also causing problem. split the design into datapath and control-unit. draw a datapath block diagram of your core -- showing alu, register file, temp-regs, data_ram and code-rom, muxes (where needed) and their intercon

Picoblaze is Ken Chapman's 8-bit microprocessor CORE optimized for Xilinx FPGA and CPLD and have very small footprint.
KCPSM stands for Constant(k) Coded Programmable State Machine
Xililinx site have a Picoblaze resource center where some could find more about the core.

Sorry to hear about you losing your job. Hopefully, you will find something quickly!
I've been using vhdl/Verilog on and off for over 10 years. I too am interested in learning System C but I'm not sure that it would give you an edge over other candidates unless you're specifically going for a System C position.
It seems like a lot o

sequential circuits are the ones which depend on present and pass input values....
This is the defintion that is e.g. given by Enoch in his profound text book Digital Logic and microprocessor design with vhdl. In so far any logic circuit with feedback, that acts as a state memory must be considered as sequential circuit. Also

Zero comparison is most likely faster in a microprocessor because they can include digital logic that automatically compares the results of operations with zero and sets a condition flag. If you want to compare something against a different value, an additional subtraction step is required.
In an FPGA or ASIC, there should be no difference becau
