how to ust FPGA to implement a microcomputer that can use for adder, subtractor ,multiplixer and divisor~~

 

[metao]

Try NIOS II (32 bit soft core) from altera
Free and good document for starter

 

[Alvinnju]

that's good

You can also select Xilinx Microblaze.And any other opensource microcontroller.

Hi,
Take a look at:

**broken link removed** :

Minimal 8-Bit CPU in VHDL - an (successful) attempt to fit an entire CPU into a 32 macrocell CPLD. Comes with source, assembler and simulator.

Has exactly what you are looking for. The others are full blown CPUs.

Hope you find it usefull,

u can get any CPU codes from net, verify that codes, modify it according to u requirement,
using any one FPGA software from XILINX or ALTERA
u undergo full design cycle and download it ur FPGA device, verify it...

then u will have a microcompter in ur FPGA

If you want to try implementing your own MPU please see : www.fpgacpu.org

 

[phoenixfeng]

you can use nios or microblaze ,which are good choice

you can also write the HDL code youself

 

[dddhacker]

You can go to www.opencores.org. A lot of free CPU cores are available there.
