Research using Tensilica's Technology

• Research
  We are comparing the performance of local memory CMP processor with shared memory CMP processors utilizing Tensilica’s technology.
• Career
  Computer Engineer (in Spanish “Informático”), five years plus final project.

• Teaching
  During 2007 and 2008, we have been preparing some lab exercises in which Tensilica’s technology is utilized for two courses: “Computer Architecture” (at pre-graduate level) and “Configurable processors and circuits” (at graduate level). Three lab exercises have been scheduled for June 2008:
  Exercise 1. Using the Xtensa software tools in Xtensa Xplorer: compiling, running, profiling, and modifying the processor configuration.
  Exercise 2. Generating TIE configurations and exploring the optimization techniques: instruction fusion, VLIW instructions, and SIMD processing.
  Exercise 3. Generating a XTMP simulator for a dual core processor.

We use the documentation prepared by Tensilica for universities. Exercises 1, 2 and 3 are Tensilica Labs 3, 5 and 4, respectively.

• Courses

Computer Architecture, 4th year – 1st semester (October 2007 - March 2008), each student receives 90 hours, 60 in classroom, 30 in laboratory.

• Topics

Processor design, memory hierarchy (cache, main memory), high-performance disk array, efficient programming, configurable hardware, computer simulation.

• Specific Outcome Using Tensilica's Tools

Each pair of students will analyze a fixed algorithm provided by the professor and try to customize the instruction set of an Xtensa processor. Cycle accurate simulations will indicate which design is the best, which will receive an honor grade.

• Key Challenge

Discovering the custom instruction set that provides the highest performance in a competitive way.

• Measure of Effectiveness

The best design will execute the algorithm in less time.

• Available Resources

A laboratory with 26 Windows XP-equipped personal computers and a team of three persons for installation and maintenance of software tools. Web site: www.dis.ulpgc.es
