The architectural representation of the Pentium processor is considered to be an advancement of 80386and 80486 microprocessors. Basically, Pentium has included modifications related to cache structure, the width of the data bus, numeric coprocessor with faster speed along with providing dual integer processor. In the case of a Pentium processor, th...
Following are the features that Pentium processor offers: 1. Superscalar architecture 2. Separate data and instruction caches 3. Bus cycle pipelining 4. Execution tracing 5. 64-bit data bus 6. Internal parity checking 7. Dynamic branch prediction 8. Dual processing support 9. Performance monitoring We have already mentioned in the beginning that Pe...
A special category of microprocessors that involves a parallel approach for instruction execution called instruction-level parallelism through which more than one instruction gets executed in one clock cycle is called superscalar processors. It is famous as a second-generation RISC processor because RISC is the ones that operate in a faster manner ...
Learn about the Pentium microprocessor, a powerful 32-bit superscalar processor introduced in 1993. See its features, architecture and block diagram with functional units and pipelines.
- Memory: Pentium Pro microprocessor have 8-bit byte memory. Two consecutive bytes form a word, four consecutive bytes form a double word. All the address in the memory are of byte formats.
- Register: There are 8 general-purpose registers present in the Pentium Pro architecture. Each register is 32-bit long. First four register are used for data manipulation and next four register are used to hold address.
- Data Formats: Integers are stored as 8-, 16-, 32-bit Binary numbers. Characters are represented using 8-bit ASCII codes. Floating points are represented using three different formats namely single-precision format, double-precision format, extended-precision format.
- Instruction Formats: All the Pentium Pro instruction uses basic format. The basic format for Pentium Pro Instructions is: Prefix: A Prefix specifies the operation of an instruction.
The simplified block diagram of internal architecture of Pentium 4 Processor is shown in Fig. 12.60 and the detailed internal architecture of Pentium 4 is depicted in Fig. 12.61.

7.2 The Pentium Processor A block diagram of the Pentium showing the major signal groups is given in Figure 7.1. In the following, we describe these signals. As mentioned in Chapter 2, the pound sign (#) is used to indicate a low-active signal: Data Bus (D0 to D63): This is the 64-bit data bus. The least significant byte is on data lines
Pentium 4 processor to have outstanding floating-point and multi-media performance. We provide some key performance numbers for this processor, comparing it to the Pentium® III processor. INTRODUCTION The Pentium 4 processor is Intel’s new flagship microprocessor that was introduced at 1.5GHz in November of 2000.
The Pentium processor’s architectural design is regarded as an improvement over the 80386 and 80486 microprocessors. In essence, Pentium includes changes to the cache structure, data bus width, and numeric coprocessor speed in addition to a dual integer processor.
