An 8-bit microprocessor is a type of central processing unit (CPU) that processes data in 8-bit chunks. This means it can handle 256 different values at a time, which is suitable for simple computing tasks. These microprocessors are often used in basic electronic devices, such as calculators and early personal computers. Introduced in the late 1970s, the 8-bit microprocessor played a crucial role in the development of computing technology. Popular examples include the Intel 8080 and the Zilog Z80, which laid the groundwork for more advanced processors. Their simplicity and efficiency made them ideal for various applications in embedded systems.
