Reconfigurable Computing
The term reconfigurable computing describes the field of reconfigurable computing systems and their applications.
Content
These are computing systems that are structurally programmable, for example on the basis of FPGAs - in contrast to conventional Von Neumann computers , whose instruction streams are programmed as instruction scheduling . The following table shows a classification scheme for computer paradigms published by Nick Tredennicks around 1995 :
| Computer class | Resources / programming source | Algorithms / programming source |
|---|---|---|
| early historical calculator | fixed / none | fixed / none |
| Von Neumann calculator | fixed / none | variable / software (command streams) |
| Reconfigurable Computing | variable / Configware (configuration) | variable / flowware (data streams) |
With reconfigurable platforms, a distinction is made between fine-grained reconfigurable, as in FPGAs with only 1-bit wide programmable logic blocks (CLBs), and coarse-grained reconfigurable with word-widths (e.g. 32-bit) reconfigurable data paths (rDPU: reconfigurable data path unit ), which are almost identical to the Are comparable to the main processor of a computer, but do not contain a program counter.
