Flex ASIC Issues

• Why own DSP cores?
• Vendor independence
• Own IP
• Use of STD ASIC flow
• Easy to move to another process
• Enables common mem. concept
• Configurable to particular application
• Possible to include dedicated HW and instructions
• Allow parallel execution of instructions
• Emulator support
