Symbian OS
The most widely-used operating system (OS) for mobile phones.
 Simple estimation methods
This refers to methods of estimating overall system performance based on ratios of CPU performance, bus bandwidth, etc. With functionally complex software, these methods of performance estimation are almost pointless.
 Accuracy of processing time simulations
In order to evaluate software performance, it is necessary to accurately obtain average processing times in regard to the processes being measured. Most software requires a millisecond-level degree of accuracy, but circuit-design testing requires nanosecond-level accuracy. Contrastingly, checking the order of operations in software execution does not require timing accuracy.
 Electronic System Level (ESL)
Unlike register transfer level (RTL), which requires an existing design, this is a level of describing hardware in terms of its broad operations for the purpose of verification.
