#176848 - ARM simpler than 8051
Responding to: ???'s previous message
I contend that an ARM processor is simpler than an 8051. The programmer isn't burdened with the having to worry about limited iram, xram, register banks and stack space. The ARM timers are also conceptually very simple. It's the simplicity that costs silicon.
