Description
A new type of Ethernet switch based on the PCI Express switching fabric is being presented. The switch leverages PCI Express peer-to-peer communication protocol to implement high performance Ethernet packet switching. The advantages and challenges of using the PCI Express as the switching fabric are addressed. The PCI Express is a high-speed short-distance communication protocol largely used in motherboard-level interconnects. The total bandwidth of a PCI Express 3.0 link can reach as high as 256 gigabit per second (Gb/s) per 16 lanes. Concerns for PCI Express such as buffer speed, address mapping, Quality of Service and power consumption need to be considered. An overview of the proposed Ethernet switch architecture is presented. The switch consists of a PCI Express switching fabric and multiple adaptor cards. The thesis reviews the peer-to-peer (P2P) communication protocol used in the switching fabric. The thesis also discusses the packet routing procedure in P2P protocol in detail. The Ethernet switch utilizes a portion of the Quality of Service provided with PCI Express to ensure guaranteed transmission. The thesis presents a method of adapting Ethernet packets over the PCI Express transaction layer packets. The adaptor card is divided into the following two parts: receive path and transmit path. The commercial off-the-shelf Media Access Control (MAC) core and PCI Express endpoint core are used in the adaptor. The output address lookup logic block is responsible for converting Ethernet MAC addresses to PCI Express port addresses. Different methods of providing Quality of Service in the adaptor card include classification, flow control, and error detection with the cooperation of the PCI Express switch are discussed. The adaptor logic is implemented in Verilog hardware description language. Functional simulation is conducted in ModelSim. The simulation results show that the Ethernet packets are able to be converted to the corresponding PCI Express transaction layer packets based on their destination MAC addresses. The transaction layer packets are then converted back to Ethernet packets. A functionally correct FPGA logic of the adaptor card is ready for implementation on real FPGA development board.

Description
This project uses fourteen transcriptions of Pete Fountain’s solos as examples to
demonstrate traditional jazz clarinet techniques and language in terms of motives,
patterns, and a variety of articulations. This project also includes guidelines on how to
practice jazz improvisation as well as how to apply Fountain’s techniques and jazz
language to one’s own improvisation. Though there are countless musicians who have
made remarkable contributions to the development of the jazz language, Pete Fountain’s
unique style is particularly worthy of study due to his massive media presence, effortless
playing techniques, unique tone quality, and showmanship throughout his career.

Description
"Chronos" is a composition by the great jazz pianist, Aaron Parks. Originally arranged for a quartet consisting of piano, upright bass, drums and tenor saxophone, I sought to arrange the piece for a sextet consisting of trombone, alto saxophone, tenor saxophone, guitar, upright, bass, and drums. This thesis outlines my process as I transcribed "Chronos" from the original recording and then arranged it for a new ensemble. It also discusses the difficulties faced in all the phases of the project from transcribing to rehearsing and performing the work. My arrangement is included with the thesis for those who wish to analyze the music as well as a recording of a live performance of my arrangement at The Nash in downtown Phoenix on April 7th, 2015.

Description
Witching Hours is the debut studio album of Chicago-born, Phoenix-residing trumpet player John Michael Sherman. It is a consummation of his work in the Arizona State University jazz studies program both as a performer and composer. Featured on the album are several other musicians who John Michael played alongside throughout his tenure at ASU, including Chaz Martineau on tenor saxophone, Evan Rees on piano, Reid Riddiough on guitar, Vince Thiefain on bass, Matt McClintock on drums, and Dan Meadows on baritone saxophone. The album features seven pieces, all original compositions or arrangements. The first track, "Workin' My Nerves", is a blues shuffle in the key of F. This is followed by "Scarborough Fair", an arrangement of the classic English folk tune in a rock style. The title track, "Witching Hours", is an cadaverous linear composition in 7/4 which is followed by "Goliath", a pseudo-tone poem about the biblical giant. "I Should Have Known" is a pensive ballad featuring an a capella intro and cadenza, followed by the most recent composition, a minor blues-esque piece entitled "Who Said That?" The final track, "Don't Change A Thing", is an upbeat samba which was written in John Michael's first year of college. These pieces demonstrate an understanding of the jazz tradition and exhibit influences from such musicians as Clifford Brown, Freddie Hubbard, Wayne Shorter, and Snarky Puppy. The album was recorded at Tempest Recording in Tempe and produced by Clarke Rigsby. Clarke is a veteran recording engineer and is the first choice of many of Phoenix's finest jazz musicians, including thesis director and head of the ASU jazz department Michael Kocour. The pieces were composed and recorded under the guidance of Mike Kocour and Jeff Libman. Witching Hours represents a culmination of John Michael's course in the Arizona State University jazz department and his endeavors as a trumpet player and composer.
