The following C function is compiled with hard floating point linkage.
float function(int a, float b, int c, float d);
Which register is used to pass argument c?
When using the Performance Monitoring Unit to count runtime events the counter registers are limited to 32-bits. How can more than 2A32 events be counted without significantly impacting the software performance?
When an interrupt service routine reads the Generic Interrupt Controller (GIC) Interrupt Acknowledge Register, what state transition occurs for that interrupt ID?
Consider a sequence of five independent instructions running on a pipelined processor. There are no interlocks and no data dependencies between instructions, and each instruction takes one cycle to execute. The processor has three pipeline stages and is not superscalar.
How many cycles does it take to fetch, decode and execute all five instructions in sequence, assuming that there are no pipeline stalls?
A program running on a development board that is connected to a host using a debugger can access a file on the host by using:
In the Generic Interrupt Controller (GIC), when an interrupt is requested, but is not yet being handled, it is in which of the following states?
In a loop termination test, how might a programmer indicate to the compiler that the loop iteration count limit is divisible by four?
When using a Generic Interrupt Controller (GIC), how does code cause a software-generated interrupt?
