  "DESIGN OF CLOCKED STORAGE ELEMENTS"

	Tuesday, January 22, 2002
		3:00 p.m.
		CIS-101


		 ABSTRACT


The clocked storage elements are the single most analyzed and debated
circuit structures in modern microprocessors. Their importance is in the
fact that they provide a boundary between the shrinking pipelined stages.
The demand for high performance mandates detailed understanding of timing
issues and the intricate inner working of timing elements. The techniques
known as "time borrowing," "slack passing" or "cycle stealing" are based
on the fact that the extra time needed could be traded with the time
allowed for the next cycle. Those techniques are increasingly used and
are intimately related to the inner workings of timing elements.

This talk will also present a number of clocked storage elements used
in modern microprocessors and discuss the timing issues and design
guidelines. We will discuss a set of rules for consistent estimation of
the real performance and power features of the Flip-Flop and Master-Slave
latch structures. The talk will point to the sources of performance and
power consumption bottlenecks in different design styles as well as to new
directions in development for low power.



			BIOGRAPHY
Prof. Vojin G. Oklobdzija, obtained Ph.D. in Computer Science from the
University of California, Los Angeles in 1982, MSc degree in 1978 and
Dipl. Ing. (MScEE) from the Electrical Engineering Department, University
of Belgrade, Yugoslavia in 1971.
>From 1982 to 1991 he was at the IBM T.J.Watson Research Center in New York
where he worked on  development of RISC architecture and processors and
super-scalar RISC, IBM RS/6000 (PowerPC) in particular, on which he
co-holds a patent on Register-Renaming. From 1988-90 he was visiting
faculty at the University of California Berkeley while on leave from IBM.
Since 1991 Prof. Oklobdzija has held various consulting and academic
positions. He was consultant to Sun Microsystems Laboratories, AT&T Bell
Laboratories, Hitachi Research Laboratories and Siemens Corp. where he was
principal architect for the new generation of embedded logic and memory
processors. Currently he is advisor to SONY and Fujitsu Labs. Prof.
Oklobdzija has academic appointment with the University of California and
various visiting academic appointments. He was a Fulbright professor in
South America were he was helping in setting the university curriculums.
Prof. Oklobdzija holds nine U.S., six European, one Japan and one Taiwan
patents and five other US patents currently pending. He is a Fellow of
IEEE and a member of American Association of the University Professors. He
is serving on the editorial boards of the Journal of VLSI Signal
Processing and IEEE Transactions on Computers and IEEE Transaction of VLSI
Systems, and as a program committee member of the International
Solid-State Circuits Conference. He was a General Chair of the 13th
Symposium on Computer Arithmetic, Vice Chair at the International
Conference on Computer Design and program committee member of the
International Symposium on VLSI Technology. He has published over 120
papers and has given over 100 invited talks and short courses in the USA,
Europe, Latin America, Australia, China and Japan.
