CDA 3101 – Fall 2011 - Homework 1 Solutions 1. 1.1 Datapath : Component of a computer found in the von Neumann architecture that mediates I/O and performs arithmetic operations. 1.2 Data : Information which is stored in memory and represented in binary bits whose usage is determined by program (software) running on the computer. 1.3 Five Components of a Computer : Memory, datapath, processor (or control), input, and output. 1.4 von Neumann Bottleneck : Term referring to the idea that the speed of the von Neumann architecture is dependent on the bandwidth or throughput of the datapath between the processor and memory. 2. More Short Answer (8 pts, 2 pt per problem) Define the following (one sentence or equation): 2.1. SPEC2006 SPEC (System Performance Evaluation Cooperative) is an effort funded and supported by a number of computer vendors to create standard set of benchmarks for modern computer systems. The latest is SPEC 2006, which consists of a set of 12 integer benchmarks (CINT2006) and 17 floating point benchmarks (CFP2006). 2.2. MIPS MIPS (originally an acronym for Microprocessor without Interlocked Pipeline Stages ) is a reduced instruction set computer (RISC) instruction set architecture (ISA) developed by MIPS Computer Systems (now MIPS Technologies). The early MIPS architectures were 32-bit, and later versions were 64-bit. 2.3. Geometric Mean The geometric mean , in mathematics, is a type of mean or average, which indicates the central tendency or typical value of a set of numbers. It is similar to the arithmetic mean, except that the numbers are multiplied and then the n th root (where n is the count of numbers in the set) of the resulting product is taken.
