The SH7080 comes equipped with the latest 0.15µm F-ZTAT technology, and with a
maximum operation frequency of 80MHz, both instructions and data can be
accessed in one cycle. ( While on-chip flash memories from other companies
also have operating frequencies of 80MHz and 100MHz, instruction branch time
generates additional stalling and because data access takes several cycles,
this has led to lower performance in some cases.) Also, with the on-chip flash
memory's large capacity of 1MByte (8Mbits), programs which have heretofore
been stored in external flash memory can now be stored in on-chip flash
memory, and CPU performance of ten times or more can be demonstrated compared
with existing technology.
