                       Thesis Title: "Investigation of DSP Datapath on Altera CPLD"

EXPERIENCE:

University of Illinois at Urbana-Champaign                                                                  Urbana, IL USA

Supervisor: Luddy Harrison, Associate Professor of University of Illinois at Urbana-Champaign

Research of ILLIAC6 Supercomputer                                                             Jan. 2007-present

        Controlled and coordinated the progress of developing communication protocol stack. The main

work included clarifying the hardware/software interface and each layer's specification, analyzing and

optimizing datapath for bandwidth, allocating global resource of device, and building up a run-time

reconfigurable solution. The whole protocol stack has almost been finished and expected to be verified

on mezzanine card soon.
        Designed the crossbar switches in the protocol stack. Crossbar switch interacts with both physical

channels and the software mapper. Changed with software scheduling, crossbar switches varied from

static routing, round-robin dynamic scheduling and fixed-length packet time-slot interchanger. The first

one fits only light overload. The second one avoids the NP-problem in static routing but provides

unpredictable bandwidth. The final version is capable to guarantee tight bandwidth for real-time

application. Crossbar switch design has been tested on development board in 200MHz frequency and

supplied up to 6.4 Gbps for each link.

Research of Processor's Micro-architecture                                                Mar. 2005-Jul. 2006

          Designed and evaluated Asymmetrical SMT (Simultaneous Multithreading) micro-architecture based on a

VLIW microprocessor.  Asymmetrical SMT executes the highest-priority thread as the ideal foreground routine,

while the system throughput and power efficiency  (the ratio of instructions to power per second) were increased

by utilizing thread-level parallelism.  The experiment results show that 4-thread asymmetric SMT architecture

can work in the same frequency as one-thread VLIW core, getting over 3 times IPC and 1.56 times power

efficiency with 34% area overhead.

The Design of High Performance DSP&CPU Microprocessor                  Oct. 2002-Mar. 2005

           Designed a VLIW microprocessor which supported by national basic research program of China. Duties

included: 1) Implemented the control path of the microprocessor in RTL level; 2) Accomplished the custom

design of 16-ports write-through  register file in transistor-level, which supported 4-issued microprocessor;

3) Verified the function on both simulation and formal methods. Many assembly programs  with sub-word

parallelism were created to verify the function of SIMD coprocessor. The chip was designed in 0.18¦Ìm CMOS

technology with over one million gates.
