 Instruction length: 16-bit fixed length for improved code efficiency

 Load-store architecture (basic operations are executed between registers)

 Delayed branch instructions reduce pipeline disruption during branch

 Instruction set based on C language

• Instruction execution time: one instruction/cycle (35 ns/instruction at 28.7-MHz operation)

• Address space: Architecture supports 4 Gbytes

• On-chip multiplier: multiplication operations (32 bits × 32 bits → 64 bits) and

multiplication/accumulation operations (32 bits

× 32 bits + 64 bits → 64 bits) executed in two

to four cycles

• Five-stage pipeline

Cache Memory:

• 1-kbyte instruction cache

• Caching of instruction codes and PC relative read data

• 4-byte line length (1 longword: 2 instruction lengths)

• 256 entry cache tags

• Direct map method

• On-chip ROM/RAM, and on-chip I/O areas not objects of cache

• Used in common with on-chip RAM; 2 kbytes of on-chip RAM used as address array/data

array when cache is enabled

Interrupt Controller (INTC):

• Nine external interrupt pins (NMI, IRQ0–IRQ7)

• Forty-three internal interrupt sources (forty-four for A mask)

• Sixteen programmable priority levels

User Break Controller (UBC):

• Generates an interrupt when the CPU or DMAC generates a bus cycle with specified

conditions

• Simplifies configuration of an on-chip debugger

Bus State Controller (BSC):

• Supports external extended memory access

 16-bit (QFP-112, TQFP-120), or 32-bit (QFP-144) external data bus

• Memory address space divided into five areas (four areas of SRAM space, one area of DRAM

space) with the following settable features:

 Bus size (8, 16, or 32 bits)

 Number of wait cycles
