Identify the Data Bus Width: The microprocessor has a 16-bit external data bus. This means it can transfer 16 bits at a time, which is equivalent to 2 bytes (since 1 byte = 8 bits). Calculate the Duration of a Bus Cycle: The bus cycle duration equals four input clock cycles. With an 8 MHz clock frequency, we can find the cycle time:

Dec 17, 2023 · The bus that carries data from an external device to RAM is known as the data bus. In a computer system, various components communicate with one another using buses, which are electrical pathways that transport data and commands. Data Bus: The data bus is responsible for the transfer of data. It connects the CPU (Central Processing Unit) with ...

Aug 9, 2023 · In this question, we are comparing two microprocessors with different external data bus widths: one with an 8-bit data bus and the other with a 16-bit data bus. The width of the data bus determines the maximum amount of data that can be transferred between the microprocessor and other devices in a single bus cycle. A wider data bus allows for a ...

Feb 15, 2023 · The maximum number of bytes that can be transferred per bus cycle is determined by the width of the external data bus. With a 32-bit external data bus, the maximum number of bytes that can be transferred per cycle is 4 bytes (32 bits / 8 bits per byte). Therefore, the maximum data transfer rate across the bus is: 4 bytes per cycle x 4 million ...

Jul 6, 2023 · The maximum data transfer rate for this **microprocessor **is 2 million bytes per second. The external data bus of the microprocessor is driven by an 8 MHz input clock. Since the bus cycle duration is four input clock cycles, each bus cycle takes 500 ns (nanoseconds) to complete (1/8 MHz = 125 ns per clock cycle * 4 clock cycles = 500 ns).

Jan 20, 2020 · 1. The External Data Bus is a data bus in which all storage devices such as: •Hard ware •USB Flash drives •Memory card etc. Are connected to it which inturn means that user devices that are connected to the computer system will have access to all the data that was store inside the Data Bus. 4. Address Bus is a bus that helps to transfer ...

Feb 8, 2023 · To calculate the maximum transfer rate of the microprocessor system, we consider key components such as the clock speed, the data bus width, and the duration of bus cycles. Clock Speed: The system operates at a clock speed of 16 MHz. This means the clock generates 16 million cycles per second. Data Bus Width: The external data bus is 16 bits ...

Jan 30, 2023 · External data bus: This bus carries the actual data being transmitted between the CPU and memory or other components. CPU cache controller: This component manages the cache memory, which is a small and fast type of memory that stores frequently accessed data for quick access but does not determine addresses in RAM.

The external data bus is a set of parallel electrical lines that allow data to be transferred between the CPU and other devices. The external data bus is often referred to as the system bus, and it consists of three types of signals: address signals, data signals, and control signals. Address signals are used to specify the memory or I/O ...

However, since the external data bus is only 16-bit, it can transfer 2 bytes of data in one cycle. The input clock frequency is 8 MHz, which means it oscillates 8 million times per second. To calculate the bus cycle duration, we divide the clock frequency by the number of clock cycles required for one bus cycle. In this case, it would be 8 MHz ...
