CSMA/CD - Carrier Sense Multi-Access / Collision Detection, a protocol used in ethernet to detect when a node is already transmitting on the shared link and to back off and attempt to use the network later.
Cycle-Based Profiling - profiling code executing on a processor by periodically saving off the current PC in a trace buffer - most often implemented by an interrupt generating counter that counts cycles and can be programmed to raise an interrupt every N cycles - the ISR associated can then service the interrupt and save off the PC each time into a trace buffer.
Cyclic Executive - an embedded software architecture which is composed of one or more main loop application(s) and interrupt service routines - the main loop(s) execute on a periodic basis - in some cases the cyclic executive may be an extension of Main+ISR such that several loops run concurrently or are multiplexed on a single CPU and provide different rates of execution - e.g. a high, medium, and low frequency executive.
