What is the maximum memory size for a microcontroller with a 16-bit address bus and 8 bit data bus?

What is the maximum memory size for a microcontroller with a 16-bit address bus and 8 bit data bus?

65,536 bytes
16 address bits, 16 address pins These processors have 8-bit CPUs with 8-bit data and 16-bit addressing. The memory on these CPUs is addressable at the byte level. This leads to a memory addressable limit of 216 × 1 byte = 65,536 bytes or 64 kilobytes.

What type of bus does a 16-bit microprocessor have?

address bus
Microprocessor sends out the address of a memory location or I/O location on address bus. In 8085 microprocessor, Address bus is of 16 bits (A0-A15) and can transfer maximum 16 bit address and hence can address 65,536 different memory locations. This bus is multiplexed with 8 bit data bus.

What is the maximum memory address space that the processor can access directly if it is connected to a 16-bit memory?

The microprocessor can access 216=65536 memory addresses, regardless of the size of data held at each memory address. If each memory address holds one byte (8 bits) of data then the total memory size that can be addressed directly is 216 bytes, which is 26 KiB=64 KiB.

How many clock cycles would it take to send 571 bytes be sent in a 19 bit parallel system?

The value in location 300 (which is the instruction with the value 1940 in hexadecimal) is loaded into the ___________ , and the PC is incremented. These two steps can be done in parallel.

What is the maximum memory size of a microprocessor with a 16 bit address bus?

64 KB
A 16-bit integer can store 216 (or 65,536) distinct values. In an unsigned representation, these values are the integers between 0 and 65,535; using two’s complement, possible values range from −32,768 to 32,767. Hence, a processor with 16-bit memory addresses can directly access 64 KB of byte-addressable memory.

How many address locations can a 16 bit microprocessor with 8 bit data bus address?

There are 16 bits gling out to the memory so it can choose 64ki locations. Then, each location contains 8 bits. The word size here may or may not match the CPU computation unit size, and this may or may not match the logical granularity in addressing.

What is a 16-bit microprocessor?

The 16 bit Microprocessor means that it has 16 address lines. A 16 bit microprocessor is having 16bit register set. It have 16 address and data lines to transfer address and data both. Hence it is 16 address lines. The maximum addresses are 2^16 means 65536.

What is the maximum supported memory size in a 16-bit architecture with 16-bit memory address of each memory address holds 1 byte data?

Since 216 is 65,536, a processor with 16-bit memory addresses can directly access 64 KB (65,536 bytes) of byte-addressable memory. If a system uses segmentation with 16-bit segment offsets, more can be accessed.

How many 16-bit I O ports can the microprocessor support?

Thus, the I/O address space can accommodate up to 64K 8-bit ports, up to 32K 16-bit ports, or up to 16K 32-bit ports. The program can specify the address of the port in two ways. Using an immediate byte constant, the program can specify: 256 8-bit ports numbered 0 through 255.

What is the maximum memory capacity in bytes for this microprocessor?

32-bit microprocessor with 32-bit instruction. First 8-bits consist of Opcode. Rest 24-bits consist operand address. Since 24 bits is used to address the operands the range of address lies between and , the maximum directly addressable memory capacity is which is equivalent to 16 Mega Bytes.

How many bytes can simultaneously traverse a 32-bit bus?

A bus cycle occurs every time data travels from memory to the CPU. For example, a 100-MHz 32-bit bus is theoretically capable of sending 4 bytes (32 bits divided by 8 = 4 bytes) of data to the CPU 100 million times per second, while a 66-MHz 16-bit bus can send 2 bytes of data 66 million times per second.

What is the difference between 32 bit and 16 bit bus?

2. a 16-bit local address bus and a 16-bit local data bus. With a 32-bit local address bus and a 16-bit local data bus, it would take 2 cycles to fetch the 32 bit instruction. A 16-bit local address bus would slow down operation due to only being able to pass half the instruction a cycle.

How many cycles does it take to decode a 32-bit address bus?

(1) If the local address bus is 32 bits, the whole address can be transferred at once and decoded in memory. However, since the data bus is only 16 bits, it will require 2 cycles to fetch a 32-bit instruction or operand. (2) The 16 bits of the address placed on the address bus can’t access the whole memory.

What is the read bus timing of an 8088 microprocessor?

15. The Intel 8088 microprocessor has a read bus timing similar to that of Figure 3.18, but requires four processor clock cycles. The valid data is on the bus for an amount of time that extends into the fourth processor clock cycle. Assume a processor clock rate of 8 MHz.

What is the maximum addressable memory capacity (in bytes) of a microprocessor?

What is the maximum directly addressable memory capacity (in bytes)? 16,777,216 bytes (16 Mbytes) b. Discuss the impact on the system speed if the microprocessor bus has
