I want to copy a block of 32' words from RAM to a 32' register in some external hardware. Can I do a move2dinit, move2dall with the following parameters? source address = address of block in RAM destination address = address of hardware register width in bytes of row = 4 number of rows = number of words to write source stride = 4 destination stride = 0 I would also like to be able to read the register several times and store the results in a block in RAM. How can I do these things from occam? The MOVE2D routine in the occam implementation manual seems to use the strides of its argument arrays. Do I have to use GUY code inserts? ======================================================================== Denis Howe uunet!mcvax!ukc!gec-rl-hrc!denis G15 GEC Hirst Research Centre denis@uk.co.gec-rl-hrc East La.
