Tutorial: Memory System 1. A S3C44B0X based system is required to be equipped with a 16-bit data bus memory system as follows: 16M bytes of ROM (4M x 16-bit) with starting address of 0x00000000. 16M bytes of SRAM (2M x 16-bit) with starting address of 0x0C000000. 8M bytes of SRAM (1M x 16-bit) with starting address of 0x0E000000. (i) Find the chip count for all the memory components. (ii) Design the address table for the memory system. (iii) Draw the memory map. (iv) Determine the Boolean expressions of

Unformatted text preview: ALL the chip select signals. (v) Draw the decoder circuits. (vi) Draw the circuit diagram for the 16M bytes of SRAM with address 0x0C000000. 2. One of the simplest approaches to design address decoder is to make use of standard decoder chip to generate the chip select signals the memory blocks are in equal size. Consider that if the memory bank 7 of the S3C44B0X is required to be divided into 8 blocks of equal size, design a circuit based on decoder chip to the 8 chip select signals....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
