What they say about CoSy

• STMicroelectronicsOur new CoSy-based FlexCC2
  shows 1.4 - 2 x performance improvement over
  FlexCC1, with a 10 code size reduction and
  reaching within 10 range of hand-crafted
  assemblyhttp//www.acm.org/sigs/sigda/Archives/P
  roceedingArchives/Date/Date2001/papers/2001/date01
  /pdffiles/06e_1.pdf
• EricssonWe are particularly impressed by the
  way CoSy can handle architecture
  parallelismhttp//www.ace.nl/products/ericsson.h
  tm
• ZilogCoSy is a development environment with
  which you can generate high-quality compilers
  very, very quicklyhttp//www.ace.nl/products/zil

11
What they say about CoSy (2)

• HitachiCoSy has cut our development costs by
  two thirds, for an initial outlay that only
  amounted to around 10 of our budget for an
  external compiler development project, plus we
  get all the benefits of IP re-use that come from
  acquiring in-house expertise in compiler
  generation
• NECAverage 5 times faster and 36 smaller code
  w. CoSy DSP-C
• Philips/AdelanteA flexible C compiler for the
  R.E.A.L. DSP architecture has been developed and
  validated by a small team in a relatively short
  timehttp//www-us.semiconductors.philips.com/acr

CoSy Performance

• Architecture 16-bit fixed point DSP
• Application Mobile communications audio and
  video codec
• Compiler platforms Commercial Vendor, CoSy out

CoSy Performance (2)

• STMicroelectronics

Graph shows performance gain in migrating from
previous compiler technology to CoSy. Nowadays,
the FlexCC2 compiler provides performance
superior to Hand-coded assembly.

Compiler Market Economics

• No Compiler ROI
• Development costs already outweigh revenues
• Product Revenues 1,000,000,000 / year
• Development Budgets 2,000,000,000
• Limitations
• Limited growth in revenues
• Development costs spiraling
• Skill shortages (professional compiler developers
  worldwide 15,000)
• Focus on reducing TCO (Total Cost of Ownership)
• Compiler Framework (technology)
• Time/effort to performance

16
Compiler Market Segmentation

• High-Performance Computing
• high margin, low volume
• NEC, IBM, Hitachi,
