Functional Description
The architecture of the XC2220U combines advantages of RISC, CISC, and DSP
processors with an advanced peripheral subsystem in a well-balanced design. On-chip
memory blocks allow the design of compact systems-on-silicon with maximum
performance suited for computing, control, and communication.
The on-chip memory blocks (program code memory and SRAM, dual-port RAM, data
SRAM) and the generic peripherals are connected to the CPU by separate high-speed
buses. Another bus, the LXBus, connects additional on-chip resources and external
resources (see Figure 3). This bus structure enhances overall system performance by
enabling the concurrent operation of several subsystems of the XC2220U.
The block diagram gives an overview of the on-chip components and the advanced
internal bus structure of the XC2220U.
