The purpose of this hardware description is to introduce the features of the equipment in the One Dimensional Signal Processing Lab and to illustrate the use of some of the standard lab setups.An overview of the lab equipment is presented.Interconnections between the lab terminals, the PDP 11-40 in the lab, and ECN are described.Detailed descriptions of the use of the terminals in controlling signal processing and file transfer software with the 11-40 are given.The basic equipment configurations for common signal processing tasks are shown.This introduction covers only a small part of the capabilities of the lab.The lab users are encouraged to extend these ideas and make use of the full flexibility of the lab for signal processing applications.1. Equipment 1.1 PDP 11-40 Computer The PDP 11-40 is the heart of the signal processing lab.Real time samples enter the computer by direct memory access (DMA) from the Kluge (FIFO queuing).Samples entering the 11-40 are typically routed immediately to disk store by DMA action.The DMA is more fully described in Appendix A. The software operating system (see "Switch II and DMC User's Manual"), provides file maintenance, signal processing operations, and file transfer between ECN and the 11-40 via a dedicated one megabaud communications line.1.2 Disk Drives The lab has two disk drives.The CDC 9766 Drive has 239 Mbytes available and is organized into 12 logical devices.The Aries Drive has 10 Mbytes organized into 5 Mbytes of disk cartridge and 5 Mbytes of system software.For further information on the organization of the drives see Appendix B. 13 Lear Siegler AdmSa Terminal The Adm3a terminal is available for usewith ECN or in controlling the PDPiHP.1.
