18 years agoAlternatives to NIOS
I'm getting a bit frustrated with NIOS and I'd like to consider alternative soft-cores. NIOS seems to be very powerful for OS implementations, but not too efficient for small microcontroller-like app...

17 years agoHi I am just checking in to see if there is still interest in this topic.
I have a new kind of embedded processor that runs this trivial test case in 51 clock cycles. 36 of the cycles are used by iterations of the for loop. 9 iterations at 4 clocks per. How does this compare to NIOS? main() { //x = 0x00ff; // 15 | 255; //x = 1; if(x == 0) if(x == 0) y = 2 + 3 * 4 - 4; else y = 5; else y = 2*3-4; while(x == 6) // if x == 6 { x = x - 7; } for(x = 0; x < 9; x = x + 1) { y = 10; } } A crude but compilable .bdf shows 5 aluts and about 45K ram bits with slack of 8.189. *******Just realized a lot of nodes were synthesized away so this data is not correct. Am I on the right track?
