A superscalar architecture is a uniprocessorthat can execute two or more scalar operations in parallel.Some definitions include superpipelined and VLIWarchitectures; others do not. Superscalar architectures(apart from superpipelined architectures) require multiplefunctional units, which may or may not be identical to eachother. In some superscalar processors the order ofinstruction execution is determined statically (purely atcompile-time), in others it is determined dynamically (partlyat run time).

Platidiam
- An inorganic water-soluble platinum complex. After undergoing hydrolysis, it reacts DNA produce both intra interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity cisplatin correlates with cellular arrest in G2 phase cell cycle.
