ARM8 is the successor to the ARM7, a low-power performance ARM microarchitecture designed by ARM Holdings for the mobile market. This microarchitecture is designed as an IP core and is sold to other semiconductor companies to be implemented in their own chips.
Architecture
Key changes from ARM7
- 2x performance (ARM810 vs ARM710 on the same process node)
- 26% lower CPI (1.4, down from 1.9)
- 0.6 µm process (down from 0.8 µm)
- 1.66x longer pipeline (5 stages, up from 3)
Die
ARM810
- 0.6 µm process
- 3.3 V
- 0.5 W
- 3-Layer Metal CMOS
- 53.5 mm² (not including pad ring)
- 144 TQFP
