the IF stage and 01 of the RD stage One translation lookaside buffer (TLB) is nsed to do address translation for both the I-cache and the D-cache The TLB is accessed during 0 1 of the IF stage, for supporting I-cache access and is accessed during <]>2 of the ALU stage, for supporting D-cache access, which takes place during the M E M cycle The register file performs first a write (0 1 of WB stage), and then a read (<|>2 of RD stage) in every machine cycle This pipeline requires a three-ported (two reads and one write) register file and a single-ported I-cache and a single-ported D-cache to support the IF and MEM stages, respectively With forwarding paths from the outputs of the ALU and the MEM stages back to the input of the ALU stage, no ALU leading hazards will incur a penalty cycle The load penalty, that is, the worst-case penalty incurred by a load leading hazard, is only one cycle with the forwarding path from the output of the MEM stage to the input of the ALU stage The branch penalty is also only one cycle This is made possible due to several features of the R2O00/R3O00 pipeline First, branch instructions use only PC-relative addressing mode Unlike a register which must be accessed during the RD stage, the PC is available after the IF stage Hence, the branch target address can be calculated, albeit using a separate adder, during the RD stage The second feature is that no explicit condition code bit is generated and stored The branch condition is generated during <|>1 of the ALU stage by comparing the contents of the referenced register(s) Normally with the branch condition being generated in the ALU stage (stage 3) and the instruction fetch being done in the IF stage (stage 1), the expected penalty would be two cycles However, in this particular pipeline design the I-cache access actually does not start until 02 of the IF stage With the branch condition being available at the end of < 1 of the > | ALU stage and since the I-cache access does not begin until 02 of the IF stage, the branch target address produced at the end of the RD stage can be steered by the branch condition into the PC prior to the start of I-cache access in the middle of the IF stage Consequendy only a one-cycle penalty is incurred by branch instructions Compared to the six-stage TYP pipeline, the five-stage MIPS R20O0/R3O00 pipeline is a better design in terms of the penalties incurred due to pipeline hazards Both pipelines have the same ALU and load penalties of zero cycles and one cycle, respectively However, due to the above stated features in its design, the MIPS R2000/R3000 pipeline incurs only one cycle, instead of four cycles, for its branch penalty Influenced by and having benefited from the RISC research done at Stanford University, the MIPS R2O00/R3O00 has a very clean design and is a highly efficient pipelined processor 2242 CISC Pipelined Processor Example In 1978 Intel introduced one of the first 16-bit microprocessors, the Intel 8086 Although preceded by earlier 8-bit microprocessors from Intel (8080 and 8085), the 8086 began an evolution that would eventually result in the Intel IA32 family of object code compatible microprocessors The Intel IA32 is a CISC architecture with variable-length instructions a n d ' complex addressing modes, and it is by far the most dominant architecture today in terms of sales volume and the accompanying application software base In 1985, the Intel 386, the 32-bit version of the IA32 family, was introduced [Crawford, 1986] The first pipelined version of the IA32 family, the Intel 486, was introduced in 1989.

Here s a final look at Searcher(). This version performs a postorder search of the tree (see Figure 11-11):

Searcher( struct Node *nodePtr ) { if ( nodePtr != NULL ) { Searcher( nodePtr->left ); Searcher( nodePtr->right ); VisitNode( nodePtr ); } }

Recursion and binary trees are two extremely powerful programming tools. Learn how to use them they ll pay big dividends.

Next on the list is the subject of function pointers. Function pointers are exactly what they sound like: pointers that point to functions. Up to now, the only way to call a function was to place its name in the source code:

MyFunction();

Keith bought a fancy new case for his system He removed the motherboard from his old case, but discovered it wouldn t t in the new one What did Keith forget to check Jeremy wants to upgrade his system by replacing the CPU His friend works at a local computer shop and has offered him a Pentium D processor for a great price! Jeremy s current system uses a Pentium 4 254-GHz CPU Will this work Why or why not

Function pointers give you a new way to call a function. Function pointers allow you to say, Execute the function pointed to by this variable. Here s an example:

int (*myFuncPtr)( float );

Fetch" instruction from the 32-byte prefetch q u e u e (prefetch unit fills a n d flushes prefetch queue) Translate instruction into control signals or microcode address Initiate address generation and m e m o r y access Access microcode memory Output microinstruction to execute unit

This line of code declares a function pointer named myFuncPtr. myFuncPtr is a pointer to a function that takes a single parameter, a float, and returns an int. The parentheses in the declaration are all necessary. The first pair ties the * to myFuncPtr, ensuring that myFuncPtr is declared as a pointer. The second pair surrounds the parameter list and distinguishes myFuncPtr as a function pointer. Suppose we had a function called DealTheCards() that took a float as a parameter and returned an int. This line of code assigns the address of DealTheCards() to the function pointer myFuncPtr:

myFuncPtr = DealTheCards;

Notice that the parentheses were left off the end of DealTheCards(). This omission is critical. If the parentheses were there, the code would have called DealTheCards(), returning a value to myFuncPtr. You may also have noticed that the & operator wasn t used. When you refer to a function without using the parentheses at the end, the compiler knows you are referring to the address of the function. Now that you have the function s address in the function pointer, there s only one thing left to do call the function. Here s how it s done:

int result;

result = (*myFuncPtr)( 3.5 );

This line calls the function DealTheCards(), passing it the parameter 3.5 and returning the function value to the int result. You could also have called the function this way:

int result;
