Th, Jan 12 Programmable DSP Architectures: Part I, Edward A. Lee Easy to read article on the most notable features of programmable DSP processors. These first-generation DSP processors were more clearly distinguished from general-purpose processors than they are today. Note the publication date of 1988--many of the technical specifications are impressive only when considered in the context of the technology available at that time.
Tue, Jan 17 Programmable DSP Architectures: Part II, Edward A. Lee Easy to read article presenting an overview of issues of programming pipelined DSP processors with complex organizations.

An On-line Verilog Reference, S. Sutherland Convenient and very nicely presented. Note that it covers aspects of verilog that shouldn't be used for sythesizable code, such as signal strengths and primitives.
Tue, Jan 31 SPIM: A Pipelined 64 x 64-bit Iterative Multiplier, M. Santoro and M. Horowitz Classic paper introduces 4:2 adder and its use in adding multiplier partial products. An iterative architecture was chosen to reduce the amount of die area required.

Historical Notes on the Fast Fourier Transform, James W. Cooley, Peter A. W. Lewis, and Peter D. Welch; Proceedings of the IEEE, October 1967. Some notes on FFT history 2 years after the seminal paper.
Th, Mar 8 Trends in Multicore DSP Platforms, Karam, AlKamal, Gatherer, Frantz, Anderson, Evans A recent paper with a thorough and detailed survey of modern multicore DSP processors
- A 28nm 0.6V Low-Power DSP for Mobile Applications, G. Gammie et al. A recent paper presented at ISSCC 2011.

Late work policy

If assignment is reviewed in class, no credit is possible for late work. If assignment was not reviewed in class, there will be a 1/3 reduction of remaining credit per day (i.e., 100% → 67% → 44% → 30% ...).

Grading errors

Please bring clear grading errors to my attention within a week of being returned to you. Non-obvious or very minor grading issues will not be considered due to fairness to all students, and the inherent subjectiveness of grading.

Submit to the instructor: 1) a short description of the suspected grading error, 2) the following statement on your regrade request with your signature immediately below it: "I certify that I have not altered this work in any way after it was returned to me. I understand that such altering would constitute a violation of the Code of Academic Conduct."
