hides f1()’s return address; we then use autoincrement addressing to pop f1()’s return address

off the stack and into the PC (r15).

We will discuss procedure linkage mechanisms for the ARM in more detail in Section 5.4.2.

2.3 TI C55x DSP

The Texas Instruments C55x DSP is a family of digital signal processors designed

for relatively high performance signal processing. The family extends on previous

generations of TI DSPs; the architecture is also defined to allow several different

implementations that comply with the instruction set.

The C55x,like many DSPs,is an accumulator architecture,meaning that many

arithmetic operations ...
