Home Documentation Hardware Benchmarks: Overo

Benchmarks of the Cortex-A8 are topping out at 1200 Dhrystone MIPS (millions of instructions per second), according to TI, which is twice the processing power as an ARM11 at the same clock speed.

The OMAP35xx Application Processors use the ARM Cortex-A8, a superscalar 32-bit CPU core. The Cortex-A8 is notable for the NEON instruction set extensions intended for multimedia processing, which use a register file and execution pipeline separate from those used for the base ARM instruction set.

In the OMAP35xx, the NEON SIMD instructions operate on integer and single-precision floating-point vectors up to 64 bits in length and are appropriate for multimedia tasks such as audio and video codecs.

As shown in the following table, the family chips of TI's OMAP family incorporate various combinations of coprocessors to augment the ARM core.
