Features of Pentium Processor are as follows:

• Superscalar architecture
• Separate data and instruction caches
• Bus cycle pipelining
• Execution tracing
• 64-bit data bus
• Internal parity checking
• Dynamic branch prediction
• Dual processing support
• 256 lines between instruction cache and prefetch buffers; allows 32 bytes to be transferred from cache to buffer
• Data cache
• 8 KB dedicate data cache gives data to execution units
• 32 byte lines
• Two parallel integer execution units
• Allows the execution of two instructions to be executed simultaneously in a single processor clock
• Floating point unit
• It includes
• Faster internal operations
• Local advanced programmable interrupt controller
• Speeds up upto 5 times for common operations including add, multiply and load, than 80486
• Branch Prediction Logic
• To reduce the time required for a branch caused by internal delays
• When a branch instruction is encountered, microprocessor begins prefetch instruction at the branch address
• Data Integrity and Error Detection
• Has significant error detection and data integrity capability
• Data parity checking is done on byte – byte basis
• Address parity checking and internal parity checking features are added
• Dual Integer Processor
• Allows execution of two instructions per clock cycle
• The other two (U pipe and V pipe) execute integer instructions
• Parallel execution of several instructions – superscalar processor
