Frequency Generator for the Spartan-3E Starter Kit 5
PicoBlaze Design Size
The images and statistics on this page show that the design occupies just 172 slices, 1 BRAM and 2 DCMs. This is only 3.7% of the slices available in an
XC3S500E device. More significantly, this slice count can be reduced to less than 32 when implementing a fixed frequency version.
Number of occupied Slices: 172 out of 4,656 3%
Number of Block RAMs: 1 out of 20 5%
DCMs: 2 out of 4 50%
Total equivalent gate count for design: 91,537
PicoBlaze makes extensive use of the distributed memory features of the
Spartan-3E device leading to very high design efficiency. If this design
was replicated to fill the XC3S500E device, it would represent the
equivalent of over 1.5 million gates. Not bad for a device even marketing
claims to be 500 thousand gates
