Abstract:
A programmable processing device comprises a plurality of universal digital blocks (UDBs) in a UDB linear array. Each register in each UDB is associated with a plurality of memory addresses, where each memory address is from each of the different memory address spaces associated with different access mode widths of different digital peripheral functions. A digital peripheral function of an access mode width is mapped to one or more contiguous UDBs starting with a first UDB in the UDB linear array. Based on the access mode width, one of the associated memory addresses is chosen for the first UDB.
