High Performance Core Architecture
The Flip-8051 core was optimized to execute multiple instructions in a single machine cycle. As a result, the average instruction is executed eight times faster than the legacy 8051 architecture. The current Virtex version of the core operates at a clock frequency of 29.8 MHz, yielding an instruction execution performance equivalent to a legacy 8051 processor operating at 238 MHz. This capability makes the core an ideal solution for low-power applications such as portable systems, sensors and smart-cards because legacy 8051 performance can be achieved at one-eighth the clock frequency.
