NRC Development

This page captures various information about the development of the NRC.

The CERN website, NRC, contains the plan and additional information.

Here are Ric's notes on the Functional Blocks of the CSC.

SCA	AsmPackCtrlReg	Switched Capacitor Array Controller block
FEX	AtlasAsmPackFexReg	Feature EXtraction block
FEX-lite	AtlasAsmPackFexLiteReg	Simple FIFO interface to FEX input header data
ROL	TBD	Read-Out Link block

Directory	Description
`common`	Common helper code
`hal`	Hardware Abstraction Layer
`rci`	Remote Communications Interface
`fee`	Front-End Electronics interface for the FEX RCEs
`rol`	Read-Out Link interface for the Formatter RCEs
`supervisor`	The bridge code for interfacing between the Control side and the Real-Time sides
