by implementing Dynamic Execution Technology and dual independent buses.1. Choose a commonly used microprocessor such as the Intel Pentium, the DEC Alpha, or the IBM/Motorola PowerPC. What data types are supported? How many bits are used to store each data type? How is each data type internally represented?Through researching Digital Equipment Corporation’s (DEC) Alpha processor I found that the following data types are supported within its architecture: integer, and floating point formats for both IEEE and VAX. I intend to briefly explain what each data type is, how many bits are used to store, and how each data type is internally represented specifically within the DEC Alpha 21164.The basic addressable unit in the Alpha architecture is the 8-bit byte. Virtual addresses are 64 bits long, however, the Alpha may support a smaller virtual address space of at least 43 bits. These virtual addresses are translated into physical memory addresses by the memory management mechanism. The following data types are described in terms of little-endian byte addressing, meaning; the bytes are numbered from right to left. Implementations may also include support for big-endian byte addressing (bytes numbered from left to right).The Alpha 21164 architecture provides support for four integer data types. Integers are “whole numbers or a value that does not have a fractional part.” (6, pg.110). Please refer to the chart below for a detailed description of each integer data type.Data TypeDescriptionByteA byte is 8 contiguous bits that start at an addressable byte boundary. A byte is an 8-bit value. A byte is supported in Alpha architecture by the EXTRACT, MASK, INSERT and ZAP instructionsWordA word is 2 contiguous bytes that start at an arbitrary byte boundary. A word is a 16-bit value. A word is supported in Alpha architecture by the EXTRACT, MASK, and INSERT instructions.LongwordA longword is 4 contiguous bytes that start at an arbitra...
