Peripheral Simulation

For Cadence Design Systems Inc. R8051XC2 (2 DPTR) — High Speed 8051 Core

Simulation support for this peripheral or feature is comprised of:

• Accurate simulation of special on-chip features.

These simulation capabilities are described below.

High Speed 8051 Core

The R8051XC features a high speed, one clock/cycle (instead of twelve clocks/cycle) 8051 CPU core. This one-cycle design allows the user to either reduce power requirements (by approximately one-eighth) without reducing speed or increase speed (by a factor of 8.1) at the same power level.
