Designing SOCs with Configured Cores

6.3. Diamond Standard Series Feature Summary

All Diamond Standard Series processor cores share a common base of 16- and 24-bit instructions. Some Diamond processor cores add 64-bit, VLIW-style instructions. Tensilica’s VLIW capability—called FLIX (flexible-length instruction extensions)—allows some of the Diamond Standard Series processor cores to issue and execute multiple independent operations per instruction. This feature significantly boosts application performance. Various key features of the Diamond Standard Series processor cores appear in Table 6.2.
