Thank you Ed. Good to know.
I'll keep also this one in my loop then.

SF02

For this, and for pointers to some other variations on the 6502 theme, and for André's own 65k project, have a look at his pages here . His project allows for 32bit, and more besides.

Really interesting project, congratulation to Andre'! Anyway I think it needs tens and tens of man years to ...

You haven't said what you want to do with it. The 6502 was not intended for multitasking and large applications compiled from high-level languages (which is what Dhrystone is all about); but OTOH, it was simple enough that writing hand-optimized assembly was far more practical on the 6502 than it ...

Here are some ideas:
lots of registers - avoids spilling to/from zero page a lot
memory bus width - 4x difference
cache - allows for harvard-like architecture internally, overlap of data and instruction activity
predication - avoids a branch penalty in many cases
more powerful instructions and ...

Hi,

Thanks a lot for your information. Really a lot and valuable.

I understood that 6502 will be better than ARM in term of interrupt latency. This is a good point!

You seem to suggest me to go for a 65816. Is there any RTL code for free? I'm interested to work on fpga.

For sure I'll have a look ...

Many thanks for your advise!

1. I'll carefully read Samuel table to understand how 0.02DMIPS/Mhz come out. It looks really low if compared to arm7 (about 0.7DMIPS/Mhz I think).

2. About ARM clone, I found two projects on www.opencores.org: Amber risc core and nnARM. They look working. Not sure yet ...

Hi all,

I'm new on this forum. I found this forum really interesting bacause it probably collects the most useful and complete information for the 6502.... and probably the most expert users.

I need to select a processor for low domanding generic applications (control, DSP like on 8bit, etc..). I ...
