Consider the following memory data sheetYou will be
designing a real-time embedded system to control an autonomous robot for
underwater use. The system consists of a single microprocessor, which will interact
with various sensors and devices on board the system. The CPU needs a 1 megabyte cache, there will
need to be about 4K of persistent storage for calibration constants, and the
main memory will need to be at least 28 MB. What would be the most judicious
assignment of memory types to specific functions in the system?

  • cache:
    DRAM, constant storage: EEPROM, main memory: UVROM
  • cache:
    EEPROM, constant storage: UVROM, main memory: SRAM
  • cache:
    Flash, constant storage: SRAM, main memory: SRAM
  • cache:
    SRAM, constant storage: EEPROM, main memory: DRAM
  • cache:
    SRAM, constant storage: SRAM, main memory: DRAM
