MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The coprocessor and the processor is connected via? Explanation: The coprocessor and the processor is connected via TEST, RQ-/GT-and QS0 & QS1 signals.

Detailed explanation-2: -Memory space is used to provide the connection between independent processor and host processor. It does not use any instructions like WAIT, ESC etc. for communication. The host processor sends the commands to the ports for managing the memory and for waking up the independent processor.

Detailed explanation-3: -Coprocessor Configuration A Coprocessor is a specially designed circuit on microprocessor chip which can perform the same task very quickly, which the microprocessor performs. It reduces the work load of the main processor. The coprocessor shares the same memory, IO system, bus, control logic and clock generator.

Detailed explanation-4: -Tightly coupled systems share a single memory space and share information through the shared common memory. Loosely coupled multiprocessors consist of distributed memory where each processor has its own memory and IO channels. The processors communicate with each other via message passing or interconnection switching.
