| Even with the possible max clock rates cyclone iii or most other fpga's delivers, Apollo core will not reach that limitation whith its actual instruction set in my opinion. But you are right, speaking of an (speculative but surely in future possible) apollo-core asic design, this would be a topic.

Would disagree here. With simple enough logic, the Cyclone III can easily reach timing at 200 MHz and more. If complexity wouldn't affect clock rate, there would be a x28 (or more) core. Achievable clock rate also heavily depends on the fill rate of the chip. As the Cyclone III has its PLLs located on the corners of the chip, clock networks can relatively easy be routed within the corresponding quadrant and you can still reach like 100Mhz. As soon as you need more chip area for your design, Fmax starts to drop drastically.

| Someone was so nice to send me result of the EFIKA. Many thanks for this.. EFIKA POWERPC 5200B @ 400 Mhz SORTBENCH 1.1 (Gunnar von Boehn) Its a CPU benchmark that stresses CPU, DCache and branch prediction. ------------------------------------------------------------- 1 K Element : 361.20 MB/sec 2 K Element : 360.60 MB/sec 4 K Element : 357.53 MB/sec 8 K Element : 219.96 MB/sec 16 K Element : 194.20 MB/sec 32 K Element : 189.11 MB/sec

| Continues improvement on the memory controller did also performance of the Core is again.

| Whenever you think they've squeezed everything out of it, they come with an announcement that they got more out of it. :D Hat off for Apollo Team. :D

| I am wonder how is this possible that one man is smarter than whole old Motorola staff?!? It seems that it is kind of fun for him what is headache for others...

| moto has practically not developed this architecture since decades, with all respect to gunnar, the team and their professionality, i dont think they are doing whats impossible. its simply a well carried out focused project.
