Figure 5-8: Normal ALU Stripe Pin assignment Figure 5-9: Specialized ALU Stripe Pin assignment 5.2 DESIGN OF THE MULTIPLEXER STRIPE The design of the multiplexer stripe is slightly different from the design of ALU stripe. In addition to the space for the multiplexer modules which form the core of the multiplexer stripe, the stripe requires additional space for routing. As can be seen from the multiplexer architecture in Figure 2-3, the multiplexer stripe is route intensive. So, a dedicated routing space needs to be made available to avoid congestion. 48
5.2.1 MUX Module Specifications As the multiplexer forms the interconnect structure, the inputs to the MUX stripe and the MUX modules are from the outputs of the ALU stripe. Figure 5-10 shows the MUX module’s logical diagram. The MUX module specifications for the hardware fabric are shown in Table 5-6. Figure 5-11 shows the placed and routed MUX Module implemented in the IBM 0.13um CMOS process. Figure 5-10: MUX Module Logical Diagram 49
