How to do better?<br />
• <str<strong>on</strong>g>Vector</str<strong>on</strong>g> Processor: potential to operate <strong>on</strong> lots of data<br />
at the same time<br />
– Multiple data elements stored in a vector<br />
– Perform the same operati<strong>on</strong> <strong>on</strong> all the data elements<br />
• Eliminates loops<br />
• FPVC does its own instructi<strong>on</strong> fetch <strong>an</strong>d execute<br />
• <str<strong>on</strong>g>Vector</str<strong>on</strong>g> instructi<strong>on</strong>s ti are dense<br />
– Reduced program code size<br />
– Reduced dynamic instructi<strong>on</strong> b<strong>an</strong>dwidth<br />
– Reduced data hazards<br />
• Parallel executi<strong>on</strong>, parallel data<br />
– Improved perform<strong>an</strong>ce
