ESD 1

1. Embedded hardware/software systems are basically designed to

• Regulate a physical variable

• Change the state of some devices

• Measure/Read the state of a variable/device

• All of these

2. Little Endian processors

• Store the lower-order byte of the data at the lowest address and the higher-order byte of the data at the highest address of memory

• Store the higher-order byte of the data at the lowest address and the lower-order byte of the data at the highest address of memory

• Store both higher order and lower order byte of the data at the same address of memory

• None of these
