V850E1 Datasheet, PDF (13/226 Pages) NEC – 32-Bit Microprocessor Core

CHAPTER 1 GENERAL
1.1 Features
(1) High-performance 32-bit architecture for embedded control
• Number of instructions: 83
• 32-bit general-purpose registers: 32
• Load/store instructions in long/short format
• 3-operand instruction
• 5-stage pipeline of 1 clock cycle per stage
• Hardware interlock on register/flag hazards
• Memory space Program space: 64 MB linear
Data space: 4 GB linear
(2) Special instructions
• Saturation operation instructions
• Bit manipulation instructions
• Multiply instructions (On-chip hardware multiplier executing multiplication in 1 clock)
16 bits × 16 bits → 32 bits
32 bits × 32 bits → 32 bits or 64 bits
