This thesis is concerned with the design of an external
multiplication package which can be utilized as an I/O device
with a PDP-8/L computer. The multiplier and multiplicand are
assumed to be 12 bit integers. The 24 bit product can be
transferred back to the accumulator of computer 12 bits...
In recent years, studies indicate that the second formant
of normal speech contains the majority of the information necessary
for speech intelligibility. This thesis presents a system to
translate the second formant frequencies to within a more adequate
hearing range of the partially deaf.
The digital speech translator, DISTRAN, utilizes...
This thesis is concerned with the logic design of a
small digital computer employing Read Only Memory(ROM) in
a special type of arithmetic unit(AU). The AU is controlled
by the ROM and is capable of performing a large number of
operations. The performance of the unit with its associated
ROM...
A cost reduction analysis is performed by coordinating
the exchange of LANDSAT (formerly ERTS) data between a CDC
3300 and a PDP8/L minicomputer. The LANDSAT data is displayed
on a 4002 Tektronix terminal by means of a grayscale output.
Large amounts of data and number manipulation are processed
in the...
This paper discusses the design strategies for interface of bus
architectures. It also describes the design of interface between the
two popular bus architectures, the Micro Channel and the Nu Bus.
The main objective of this thesis is to develop a procedure for
bus interface design and use this procedure...
This paper describes the design and implementation of
"A multiprocessor node for communication and control"
(MPCC). MPCC is a high speed, high performance local area
network capable of performing real time control tasks. This
is achieved by the concurrent operation of two 8051
microcontrollers, a dual port RAM and the...
Rapid advances in technology have seen computing move from a
large central computer to desktop microcomputers.
This advance was also
seen in the design of dedicated computers, computers designed to perform a
few specialized tasks or duties.
These computers, or microcontrollers, are
often controlled by a central computer and themselves...
In this is paper, an implementation of a microprocessor
based distributed control system (DCS) is investigated. This
system consists of a digital PID controller and a high
level operator interface. A temperature control system
was designed to experimentally verify the system operation.
Experimental results compare closely with theoretical
prediction. The...
This paper describes the design and implementation of
COLAN V, a High Performance Local Area Network for
Communications and Control utilizing a Communications Coprocessor.
The main objective of this thesis is to improve upon
the performance of previous COLANs in speed, switching
techniques and error detection techniques. This was
possible...
