PL516 Assembly language(PL516) Developer Hiring Guide

PL516 is an assembly language used for computer software programming, specifically designed for the Philips P800-family microprocessors. It was developed in the late 1970s and early 1980s, as a low-level language that directly manipulates hardware and system resources. The PL516 assembly language allows programmers to write code that is specific to the hardware of a particular machine. This language was instrumental in the development of real-time systems due to its efficiency and speed. Information about PL516 can be found in historical documents from Philips Semiconductors, now NXP Semiconductors.

First 20 minutes

General PL516 Assembly language(PL516) app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in PL516 Assembly language(PL516) application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

What are the basic components of a PL516 Assembly language program?
The basic components of a PL516 Assembly language program include directives, labels, comments, and instructions.
How would you define a label in PL516 Assembly language?
A label in PL516 Assembly language is defined by writing the label name at the beginning of a line followed by a colon.
What is the purpose of the ORG directive in PL516 Assembly language?
The ORG directive is used to set the program counter to a specific address.
How would you use the DB directive in PL516 Assembly language?
The DB directive is used to define a byte of data. For example, 'DB 0x10' would define a byte with the value 16.
Describe the difference between the JMP and CALL instructions in PL516 Assembly language.
The JMP instruction is used to unconditionally jump to a specified address, while the CALL instruction is used to call a subroutine at a specified address.

Next 20 minutes

Specific PL516 Assembly language(PL516) development questions

The next 20 minutes of the interview should focus on the candidate's expertise with specific backend frameworks, their understanding of RESTful APIs, and their experience in handling data storage and retrieval efficiently.

What are the different addressing modes in PL516 Assembly language?
The different addressing modes in PL516 Assembly language include immediate, direct, indirect, and indexed addressing.
How would you use the MOV instruction in PL516 Assembly language?
The MOV instruction is used to move data from one location to another. For example, 'MOV R1, R2' would move the data in register R2 to register R1.
What is the purpose of the RET instruction in PL516 Assembly language?
The RET instruction is used to return from a subroutine. It pops the return address from the stack and jumps to that address.
Describe the difference between the PUSH and POP instructions in PL516 Assembly language.
The PUSH instruction is used to push a value onto the stack, while the POP instruction is used to pop a value from the stack.
How would you use the ADD instruction in PL516 Assembly language?
The ADD instruction is used to add two values. For example, 'ADD R1, R2' would add the values in registers R1 and R2 and store the result in R1.

The ideal back-end app developer

What you’re looking to see on the PL516 Assembly language(PL516) engineer at this point.

At this point, a skilled PL516 Assembly language(PL516) engineer should demonstrate strong problem-solving abilities, proficiency in PL516 Assembly language(PL516) programming language, and knowledge of software development methodologies. Red flags include lack of hands-on experience, inability to articulate complex concepts, or unfamiliarity with standard coding practices.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with PL516 Assembly language(PL516).

What does this simple PL516 code do?
MOV R1, #10
ADD R1, #5
MOV R0, R1
This code snippet is moving the value 10 into register R1. Then it adds 5 to the value in R1. Finally, it moves the result from R1 to R0. So, the final value in R0 will be 15.
What will be the output of this PL516 code?
MOV R0, #5
MOV R1, #10
SUB R0, R1
MOV R2, R0
This code is moving the value 5 into register R0 and the value 10 into R1. Then it subtracts the value in R1 from the value in R0. The result is then moved into R2. So, the final value in R2 will be -5.
What does this PL516 code do that involves array manipulation?
MOV R0, #0
MOV R1, #5
MOV R2, #10
MOV R3, #15
MOV R4, #20
MOV R5, [R0, R1, R2, R3, R4]
This code is creating an array of 5 elements with values 0, 5, 10, 15, and 20 in registers R0, R1, R2, R3, and R4 respectively. Then it moves the array into R5.
What does this PL516 code do that involves threading or concurrency?
MOV R0, #1
MOV R1, #2
MOV R2, #3
MOV R3, #4
MOV R4, #5
MOV R5, [R0, R1, R2, R3, R4]
MOV R6, R5
MOV R7, R5
This code is creating an array of 5 elements with values 1, 2, 3, 4, and 5 in registers R0, R1, R2, R3, and R4 respectively. Then it moves the array into R5. After that, it copies the array from R5 to R6 and R7, simulating a concurrent operation.

Wrap-up questions

Final candidate for PL516 Assembly language(PL516) Developer role questions

The final few questions should evaluate the candidate's teamwork, communication, and problem-solving skills. Additionally, assess their knowledge of microservices architecture, serverless computing, and how they handle PL516 Assembly language(PL516) application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the different types of conditional branch instructions in PL516 Assembly language?
The different types of conditional branch instructions in PL516 Assembly language include BEQ (branch if equal), BNE (branch if not equal), BGT (branch if greater than), and BLT (branch if less than).
How would you use the SUB instruction in PL516 Assembly language?
The SUB instruction is used to subtract one value from another. For example, 'SUB R1, R2' would subtract the value in R2 from the value in R1 and store the result in R1.
What is the purpose of the NOP instruction in PL516 Assembly language?
The NOP instruction is a 'no operation' instruction. It does nothing and is often used for timing purposes or to occupy space that will be replaced with other instructions later.
