Startup.asm for 8051 uC

Hi Jan,
I am a little bit confused about this.
Does startup.asm/.a51 necessary for any firmware code?
Why some of the firmware uses starup.asm?
The keil site state that it clears internal and external data memory, etc, but why I use startup, Am I can't clear it in my firmware C code?
What benefits I can get in using startup.asm, does it affect the speed, code size,etc?
BTW, I use Silabs f340 uC.
thanks and regards
gi
