The architecture of the XC161 combines advantages of RISC, CISC, and DSP
processors with an advanced peripheral subsystem in a very well-balanced way. In
addition, the on-chip memory blocks allow the design of compact systems-on-silicon with
maximum performance (computing, control, communication).
The on-chip memory blocks (program code-memory and SRAM, dual-port RAM, data
SRAM) and the set of generic peripherals are connected to the CPU via separate buses.
Another bus, the LXBus, connects additional on-chip resources as well as external
resources (see
This bus structure enhances the overall system performance by enabling the concurrent
operation of several subsystems of the XC161.
The following block diagram gives an overview of the different on-chip components and
of the advanced, high bandwidth internal bus structure of the XC161.
