Questions & Answers

Q: What is the difference between One Human and Howard architecture in terms of memory access?

One Human architecture has common memory for data and code, while Howard architecture has separate memories. One Human allows for bi-directional access for both data and code, while Howard has bi-directional access for data and read-only access for code.

Q: How does memory type differ between One Human and Howard architecture?

In One Human architecture, data and code memory is the same and requires Random Access Memory (RAM). In Howard architecture, data memory requires RAM for bi-directional access, while code memory only requires Read-Only Memory (ROM).

Q: What is the difference in addressing between One Human and Howard architecture?

One Human architecture has common addressing for both data and code access, while Howard architecture has separate addresses for data and code access.

Q: How does execution of code differ between One Human and Howard architecture?

In One Human architecture, code execution is serial and requires more machine cycles. In Howard architecture, code execution can happen in parallel with data execution, reducing the number of machine cycles needed.

Key Insights:

• One Human architecture has common memory for data and code, while Howard architecture has separate memories.
• Howard architecture allows for parallel execution of code and data, reducing the number of machine cycles needed.
• One Human architecture requires less space and cost compared to Howard architecture.
• Howard architecture provides better performance due to parallel access of data and code.
• Arm has adopted Howard architecture for its microcontrollers and microprocessors for increased performance.
• One Human architecture is cheaper but slower, while Howard architecture is costlier but more efficient.

Summary & Key Takeaways

• One Human architecture has a CPU and memory with common memory for data and code, allowing for bi-directional access for data and code.

• Howard architecture has separate memories for data and code, with bi-directional access for data and read-only access for code.

• One Human uses RAM for both data and code, while Howard uses RAM for data and ROM for code.
