A method of caching commands in microprocessors having a plurality of arithmetic
units and in modules having a two- or multidimensional cell arrangement is provided.
The method includes combining a plurality of cells and arithmetic units to form
a plurality of groups, assigning a cache unit to a group, and connecting the cache
unit to a higher level unit via a tree structure. The cache unit may send requests
for required commands to the higher level cache unit, which may return a command
sequence including the required command, if the higher level cache unit holds the
first command sequence including the required command in the higher level cache
unit's local memory.
