MB86330
MB86330 is 16-bit Fixed-point DSP manufactured by Fujitsu Media Devices Limited.
DESCRIPTION
The MB86330 is a 16-bit fixed-point DSP (Digital Signal Processor) that is based on Fujitsu-specific Dual-MAC architecture, and can implement product addition operations and double transfer at a high rate and under low power consumption. The DSP supports a set of instructions optimum for digital signal processing in munications applications such as handy phones. The MB86330 consists of a core section and a peripheral section. For detailed specifications of the core section, see MB86330DSP Core Section Specifications. s FEATURES
- Fixed-point operations Multiplication: 16 bits × 16 bits → 31 bits Addition: 40 bits + 40 bits → 40 bits Product addition: 40 bits ±16 bits × 16 bits → 40 bits Maximum operation speed: 100 MIPS at 3.3 V
- Memory configuration Data RAM: Two sectors that can be accessed concurrently An external RAM (ERAM) is supported. Memory mapped I/O system characterized by allocation of I/O devices in the memory space Instruction RAM: 48 Kwords × 16 bits Table RAM: 16 Kwords × 16 bits
