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 
