Figure 7 illustrates how to connect a 20 ns static RAM with a 33

MHz. DSP56001. The important parameters are TDW < 10 ns,

TDOE < 10 ns, and TAA = 20 ns maximum. A 7.5 ns PLD is used

to minimize decoding delays. This example maps the static RAM

into the ranges X:$1000-1FFF and Y:$1000-1FFF. The PLD

equation is:

RAM_ENABLE = PS & !DS & !A15 & !A14 & !A13 & !A12
