8 | The objectives of this task are to provide the 2 HAS back-ends of the COACH project and |
---|
9 | a tool that adapt the coprocessor frequency to the FPGA-SoC frequency as given |
---|
10 | by the processors and the BUS. |

---|
13 | The HAS back-ends as shown in figure~\ref{archi-hls} reads \xcoach data and provides |
---|
14 | \xcoachplus data, i.e. \xcoach data annotated with hardware information such as |
---|
15 | variables bindings to registers, operations bindings to cells and a schedule. The \xcoach format |
---|
16 | being generated by {\specXcoachToC} deliverable and \xcoachplus being treated by |
---|
17 | \novers{\specXcoachToSystemC} and \novers{\specXcoachToVhdl} deliverables, |
---|
18 | this task is very dependen on task~1. |
---|
19 | \par |
---|
20 | For the two HAS front-end, this task is based on the already existing HLS tools GAUT and |
---|
21 | UGH. These tools are complementary and not in competition because they cover respectively |
---|
22 | data and control dominated designs. |
---|
23 | The organization of the task is firstly to integrate quickly the existing HLS to the COACH |
---|
24 | framework. Secondly these tools will be improved to allows to treat data dominated application |
---|
25 | with a few control for GAUT and control dominated application with a few data processing |
---|
26 | for UGH. This will enlarge the domain the HLS can cover. |

65 | \item In FPGA-SoC, the frequency is given by the processors and the BUS. The coprocessors |
---|
66 | generated by HLS synthesis must respect this frequency. However, the HLS tools can not |
---|
67 | guarantee that the micro-architectures they generate accurately respect this |
---|
68 | frequency. This is especially the case when the target is a FPGA device, because the |
---|
69 | delays are really known only after the RTL synthesis and that estimated delays used |
---|
70 | by the HLS are very imprecize. The goal of this \ST is to provide a tool to adapt |
---|
71 | the coprocessors frequency to the FPGA-SoC frequency after the coprocessor RTL |
---|
72 | synthesis. |
