T 3: Analyze the following decoding circuit and answer the questions (52=10 points ) What is the address range of the RAM if its capacity is 32KB ? What is the maximum capacity of the ROM that can be used? Which partition(s) can be accessed using Absolute Short addressing mode? What is the effective address range of the PIA (RS1=A1&RS0=A0) ? Generate the signals: VPA*, DTACK* \& BERR* (to detect accessing unused memory partitions). Design a decoding circuit that achieves the following specs and answer the questions - Split the 1 MB space into 2 partitions; the lower for asynchronous devices and the upper for the asynchronous devices - The low portions supports ROM, SRAM \& DRAM - The upper portion supports PIA, PTM, SIA and DMA - What is the address range of the RAM if its capacity is 32KB ? - What is the address range of the RMM if its capacity is 16KB ? - What is the maximum capacity of the ROM that can be used? - Which partition(s) can be accessed using Absolute Short addressing mode? - What is the effective address range of the PIA (RS1=A1&RS0=A0) ? SIA (RS=A0) - Generate the signals: VPA*, DTACK* \& BERR*
