On this issue I'm reporting: A bug(?) I found when trying to declare a parameter as a packed array (note that issue #846 refers to unpacked arrays). A suggestion/request to improve the error message displayed on unsupported features. I w...
Packed array flattening is fairly fundamental to how Verilator works, and while there might be some workaround possible to get the information, regardless there is no way in VCD format to express multidimensional packed arrays. wsnyder closed this as completed Oct 12, 2021 Member wsnyder ...
The suggested solution is not always acceptable: One problem with unpacked arrays is that you can't use them to interface between two modules. Is there any intention to support a packed arrays of packed struct in future Quartus releases? Has someone raised an SR? Tha...
If you have fairly large arrays of structures, this option may save some space, but it trades off memory with runtime efficiency. In these examples, the additional keywords packed and unpacked are illustrated; many compilers achieve the same result with #pragma directives. Inflating Structures Two...

Thus the algorithm's goal is to encode and decode byte arrays to conform to the MIDI standard while transferred in MIDI SysEx messages. From the DSI TETRA Manual Page 67: Packed Data Format Data is packed in 8 byte “packets”, with the MS bit stripped from 7 parameter bytes, and ...
11.The apparatus of claim 8, wherein the instruction includes a control field, wherein one or more bits of the control field correspond to the first lane and indicate that the lowest order data elements of the first and second operands are to be unpacked, and wherein one or more bits of...
In view of the foregoing and particularly the discussions of FIGS. 8 through 12 it is seen that the transformation between packed and unpacked format of FIGS. 7 and 8 can be performed very rapidly since a sequence of zero-valued coefficients (enhanced by zig-zag ordering) can be processed ...
