The Collider Detector at Fermilab (CDF) uses a FASTBUS network for real-time data acquisition (DAQ) with the current system comprising more than 500 FASTBUS modules. A central element in the DAQ pipeline is a hardware event builder whose role is to read out the front end scanners, reformat the data into YBOS bank structure, and transmit the data to a Level 3 trigger system which is composed of multiple processors from the Advanced Computer Project (ACP) at Fermilab. This paper describes the development of the hardware event-builder and includes some results from testing the prototype in reading out the detector, reformatting the data and writing it to the Level 3 ACP farm.
