Slide 6 of 16
Notes:
EXAMPLE: Z80 emulator at uni: someone wrote inline assembler to speed up common instructions, but tools cranky and unreliable. Turned out in end that system was too fast even in plain C (to simulate a Sinclair Spectrum on a Sun 3/60) and the inline code was never used.
- Have you sorted out the high-level things (such as good algorithms) before tinkering at a low level?
- Put off low-level and non-reusable optimisations (eg inline assembler) until design is mature and all other avenues closed.
