Next, let’s interface both program ROM and data RAM to 8051, Let’s say we want to interface 16KB data RAM, 16KB program ROM, and 16KB of data RAM, then we’ll have to follow the following steps: Step 1: Calculate the number of address lines required to …
Address decoding from memory map - Electrical Engineering …
Webdecode the addresses, the best option is to use a PLD. For example, the FPLA 82S103 has 16 inputs and 9 macrocells (i.e. 9 outputs). It could therefore decode any addresses needed. Alternatively, two level of decoding could be used as shown in figure 8.10. Here two EPLDs are used, the first decodes the upper address bits for the memory WebFor other form factors (such as soldered RAM in laptops), the module may be represented by the UDIMM graphic in the DIMM results screen. An example of a laptop with 1 soldered module and 1 SODIMM slot is shown below. Supported platforms.
