使用HLS實現霍夫曼編碼c

當我嘗試使用Vivado HLS進行系統化時，我得到了有關不可合成類型的錯誤。我的項目是關於huffman編碼。使用HLS實現霍夫曼編碼c

@I [HLS-10] Starting code transformations ... 
@I [HLS-10] Checking synthesizability ... 
@E [SYNCHK-11] huff.c:17: Constant 'temp' has an unsynthesizable type '[13 x %struct.tnode.0.2.4]*' (possible cause(s): structure variable cannot be decomposed due to unsupported type conversion or memory copy operation). 
@E [SYNCHK-11] huff.c:21: Constant 'ptemp' has an unsynthesizable type '[13 x %struct.tnode.0.2.4*]*' (possible cause(s): pointer to pointer or global pointer). 
@E [SYNCHK-72] huff.c:24: unsupported c/c++ library function 'qsort'. 
@E [SYNCHK-41] huff.c:38: unsupported pointer reinterpretation from type '%struct.tnode.0.2.4 = type { %struct.tnode.0.2.4*, %struct.t...' to type 'i8*' on variable 'ptemp'. 
@E [SYNCHK-42] huff.c:47: pointer comparison is not supported. 
@I [SYNCHK-10] 5 error(s), 0 warning(s). 
@E [HLS-70] Synthesizability check failed.

而且在做C模擬器時也有一些困難。

附件包括我的「頂級功能」的代碼。我對HLS工具沒有經驗。有人可以幫我解決這個問題嗎？我們如何將數據結構包含在Vivado HLS的頂層函數中？謝謝

如果您在導致問題的問題中添加了簡短的示例代碼，並且可能只關注單個問題，那將會很有幫助。 –
