Data Hazard Instruction depends on result of instruction still in the pipeline Control Hazard Instruction fetch depends on the result of instruction in pipeline Simple example: MIPS pipeline with a single unified memory No separate instruction & data memories Load/store requires data access Instruction fetch would have to stall for that cycle The print_string system call (system call code 4) is passed a pointer (memory address) to a null-terminated string, which it writes to the console. The print_int system call (system call code 1) is passed an integer and it prints the integer on the console. The exit system call (system call code 10) indicates the end of the program.
In MIPS pipeline with a single memory ! Load/store requires data access ! Instruction fetch would have to stall for that cycle ! Would cause a pipeline “bubble” ! Hence, pipelined datapaths require separate instruction/data memories ! Or separate instruction/data caches MIPS is a ‘typical’ RISC architecture: it has a simple and regular instruction set, only one memory addressing mode (base plus displacement) and instructions are of fixed size (32 bit). Surprisingly, it is not very simple to write assembly programs for MIPS (and for any RISC machine for that matter).
Core Timer. The MIPS CPU has a general purpose timer (core timer) that counts at ½ the CPU clock rate. The core timer is accessed through the CP0 registers (refer to Example 4 and Example 5). The timer can be configured to generate an interrupt when a specified value is reached. • Memory access (read or write) ECE232: MIPS Control 12 Adapted from Computer Organization and Design, Patterson&Hennessy, UCB, Kundu,UMass Koren MulticycleDatapath(overview) Registers Read Reg1 A L U Read Reg2 Write Reg Data P C Address Instruction or Data Memory MIPS-lite Multicycle Version A B ALU-Out Instr-uction Register Data Memory Data ...

All TCP/IP headers store integers in big endian format (called network byte order.) Binary data is written out to memory as a multibyte integer and then read back as individual bytes or vise versa. Endianness does not apply to the order of array elements.
A typical memory representation of C program consists of following sections. Initialized data segment. Uninitialized data segment. A text segment , also known as a code segment or simply as text, is one of the sections of a program in an object file or in memory, which contains executable instructions. As a memory region, a text segment may be ... the current PC from instruction memory • Second, we need to decode the instruction • Third, we grab the values from the register file • Fourth, we need to perform ALU operations on the values • Fifth, the output from the ALU goes to back to the register file and/or data memory

The three ISA's MIPS32, MIPS64, and microMIPS will be open sourced but not the new nanoMIPS ISA. nanoMIPS is the more modern one without branch delay slots and leads to an extremely reduced memory footprint. I guess they think that one is too valuable to open source. Evidently MIPS is not diving into open source with everything just yet.

A MIPS memory address is 32 bits (always). • be able to write a simple exception handler for a MIPS machine Introduction Branches and jumps provide ways to change the control flow in a program. Count the number of words in the string. Where you may not be right is that according to MIPS, only 16 bits are read from memory. This doesn't matter much if you're reading from RAM, but for memory-mapped I/O, some peripherals will change state when a "memory" location -- for example, a FIFO read will read the top of the FIFO and then pop.

“The chapter looks at how compilers represent data for MIPS programs, at argument passing for functions, and at the use of the stack. In all cases, it draws all examples from the C language, though essentially the same conventions apply to other languages. When you define data in C, the data you get in memory is compilation-target dependent. MIPS memory usage MIPS systems typically divided memory into three parts, called seg-ments. These segments are the text segment which contains the program’s instructions, the data segment, which contains the program’s data, and the stack segment which contains the return addresses for func- Used to stand for Microprocessor without Interlocked Pipeline Stages.
