Speaker: 

David Patterson (UC Berkeley)

In the 1980s, Mead and Conway democratized chip design and high-level language programming surpassed assembly language programming, which made instruction set advances viable. Innovations like Reduced Instruction Set Computers (RISC), superscalar, and speculation ushered in a Golden Age of computer architecture, when performance doubled every 18 months. The ending of Dennard Scaling and Moore’s Law crippled this path; microprocessor performance improved only 3% last year! In addition to poor performance gains, Spectre recently demonstrated timing attacks on modern microprocessors that leak information at high rates.

The ending of Dennard scaling and Moore’s law and the deceleration of performance gains for standard microprocessors are not problems that must be solved but facts that if accepted offer breathtaking opportunities. We believe high-level, domain-specific languages and architectures, freeing architects from the chains of proprietary instruction sets, and the demand from the public for improved security will usher in a new Golden Age for computer architecture. Aided by open source ecosystems, agilely developed chips will convincingly demonstrate advances and thereby accelerate commercial adoption. The instruction set philosophy of the general-purpose processors in these chips will likely be RISC, which has stood the test of time. We envision the same rapid improvement as in the last Golden Age, but this time in cost, energy, and security as well as in performance.

Like the 1980s, the next decade will be exciting for computer architects in academia and in industry!

In celebration of the 50th anniversary of computer science at UC Berkeley and the university’s sesquicentennial, EECS and the Simons Institute are launching a special series of lectures by winners of the ACM A.M. Turing Award, considered the field’s equivalent of a Nobel Prize. In addition to their technical talk, the lecturers will reflect on their time at UC Berkeley and look toward the future of research and technological development in their fields.

Light refreshments will be served before the lecture at 3:30 p.m.
