Verification Engineer or Senior Verification Engineer SOC at MIPS India

Hello Dear Readers, Currently, at MIPS India  vacancy for a Verification Engineer or Senior Verification Engineer SOC role. We are seeking an experienced Verification Engineer or Senior Verification Engineer SOC. This position involves extensive hands-on experience with CPU verification using industry-standard functional verification methodologies, formal verification, and constrained random generators, and reference model-based checkers. The candidate must be able to take critical decisions and completely own verification closure for a block or feature. This position involves cross-functional interaction with CPU designers and architects and working across sites to ensure high-quality CPU designs for customers. You will: Take full ownership and drive verification efforts to closure Work closely with designers and architects to understand specifications at unit/top level Understand use cases and develop functional test plans Develop directed tests written in C, Assembly, and SystemVeri

ARM Assembly Language Practice Question And Answer Part-4

  Hello Dear Readers,   Today in this post I will provide some basics to advanced ARM's assembly language practice QA part-4, I have used the Keil tool for code writing. Q-1).  Write an assembly language program that performs a mode change by modifying the contents of the CPSR.    a. The mode you should change to is user mode, and you have to modify the mode field of CPSR by the value of 0x10.    b. This assumes that the current mode is a privileged mode such as supervisor mode. Code: ; program which changes the microprocessor mode  masking equ 0x1f  user_mode equ 0x10   area change, code, readonly entry   MRS R0,CPSR; read the status of the microprocessor   BIC R0, R0,#masking; apply the masking bit   ORR R0,R0,#user_mode ; set the mode user_mode   MSR CPSR_C,R0 ; written back with control_field_mask   END  Output: Q-2).  Write an assembly language program that generates Software Interrupt (SVC) to perform an operation either addition or multiplication of 3 registers based on valu

ARM Assembly Language Practice Question And Answer Part-3

  Hello Dear Readers,   Today in this post I will provide some basics to advanced ARM's assembly language practice QA part-3, I have used the Keil tool for code writing. Q-1).  Create a stack that starts from address 0x5000 and contains 5 values, and the stack pointer always points to the uppermost value. Code: ; program to create stack and store 5 values  area stack, code, readonly  entry  ldr r13,=0x5000  ldr r1,=10  ldr r2,=11  ldr r3,=12  ldr r4,=13  ldr r5,=14  STMDB SP!,{r1-r5}  add r4,r3,r5  end  Output: Q-2).  Write a code to find the multiplication of 10 numbers stored consecutively starting from 0x4000. Code: ; program of the multiplication of the 10 numbers  area mul, code, readonly  entry  mov r0,#0x4000  mov r1,#9  ldr r2,[r0]  next    add r0,r0,#4    ldr r3,[r0]    muls r2,r3,r2    subs r1,r1,#1     bne next     add r0,r0,#44     str r2,[r0] stop b stop  end Output: Q-3).  Write an assembly language program to perform dot product of two vectors using a subroutine.
