Peripheral Simulation

For Hynix Semiconductor GMS90L320 — 4 Clocks per Machine Cycle

Simulation support for this peripheral or feature is comprised of:

• Accurate simulation of special on-chip features.

These simulation capabilities are described below.

4 Clocks per Machine Cycle

The standard 8051 MCU requires 12 clocks per machine cycle. The DS89C420 MCU is a high-speed 8051-compatible core that requires only 4 clocks per machine cycle. As a result, the fastest instruction on a standard 8051 will execute 3 times faster on the DS89C420 MCU.
