The co-design ladder In the past: Hardware/software codesign
{"Image DocumentName": "The co-design ladder In the past: Hardware/software codesign", "Image ImageDescription": "Hardware and software design technologies were very different. Recent maturation of synthesis enables a unified view of hardware and software. Hardware/software codesign Implementation. Assembly instructions. Machine instructions. Register transfers. Compilers. (1960 s,1970 s) Assemblers, linkers. (1950 s, 1960 s) Behavioral synthesis. (1990 s) RT synthesis. (1980 s, 1990 s) Logic synthesis. (1970 s, 1980 s) Microprocessor plus program bits: software VLSI, ASIC, or PLD implementation: hardware Logic gates. Logic equations / FSM s. Sequential program code (e.g., C, VHDL) The choice of hardware versus software for a particular function is simply a tradeoff among various design metrics, like performance, power, size, NRE cost, and especially flexibility; there is no fundamental difference between what hardware or software can implement.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
