While аddress decоding lоgic dоes аllow for аn external component to be memory-mapped to some range(s) of memory addresses, additional control signals are sometimes necessary to make this mapping meaningful. For example, when memory-mapping an input port to the data memory space of an ATxmega128A1U via the relevant EBI system, the input port should be enabled by way of both [1] appropriate address decoding logic and [2] the read enable signal provided by the EBI system. To determine why this is the case, consider the relevant EBI read cycle timing diagram, given in § 36.1 of the 8331 manual. Overall, in this course, an equation that is used to enable an external component is typically (and unsurprisingly) referred to as an enable equation. Such an equation is also referred to as a control equation or chip select equation (not to be confused with the chip selects of the EBI system), as well as some other things. ———————————————————————————————————— In regard to the relevant hardware expansion, define an enable (or control) equation for each component that is to be memory-mapped. Each control equation should be defined in terms of the relevant chip select signal(s) and, only if necessary, any other relevant EBI signals (e.g., additional address signals, the read enable signal, the write enable signal, etc.). As an arbitrary example, control equations for an SRAM, input port, and output port could be defined as follows, where `...` is meant to be replaced with an appropriate Boolean equation.
Fоr the remаinder оf this аssignment, yоu will design а hardware expansion for the OOTB µPAD. The expansion must consist of [1] an 8-bit input port, [2] an 8-bit output port, [3] the SRAM component located on the OOTB Memory Base, [4] eight SPST switch circuits, each with a "pull-up" (not "pull-down") resistor, [5] eight active-high (not active-low) LED circuits, and [6] any other components that are appropriate for items [1]-[5]. The I/O ports and SRAM must be memory-mapped to the data memory space of the ATxmega128A1U, by way of the EBI system. The pull-up SPST switch circuits must drive the "inputs" of the input port, and the "outputs" of the output port must drive the active-high LED circuits. Overall, a minimal amount of external digital logic (gates) must be used to implement the relevant design. As a simple example of this, consider some active-high enable signal. If this enable signal is to be used to enable one of two components, where the only difference between these two components is activation level (i.e., one is activated by an active-high signal and the other by an active-low signal), then clearly the component that is active-high should be chosen over the active-low one. Otherwise, for the active-low component to be enabled properly, an additional inverter component would be necessary. Below, an additional set of constraints is given to specify exactly how the relevant components must be memory‑mapped. ————————————————————————————————— Memory-mapping constraints: (Overall) The SRAM 3-PORT ALE1 mode of the EBI system must be utilized. Whenever appropriate, address decoding must be performed by way of chip select signals; external circuitry may only be utilized for address decoding when a single chip select is not sufficient. All external circuitry used for memory-mapping must be implemented with [1] a PLD kit given in 3701 (or one from 4712) and [2] a minimal amount of digital logic. (SRAM) By way of full address decoding, the SRAM component must be fully addressable and have its first address correspond to the data memory address 0x108000. Only chip selects CS0 and CS1 may be utilized. If only one chip select is needed, CS0 must be used; if two chip selects are needed, both CS0 and CS1 must be used. (Study the OOTB Memory Base schematic to determine which chip selects are needed and why.) (I/O Ports) Both the input port and output port must only be accessible via the sixty-four consecutive addresses starting at address 0x1F0000. Only chip selects CS2 and CS3 may be utilized. If only one chip select is needed, CS2 must be used; if two chip selects are needed, both CS2 and CS3 must be used.
