Description
The Oki ML675200 and ML67Q5200 Application Specific Standard Products (ASSP) devices are targeted at the growing
market for applications using the MP3 audio processing compression protocol. Available in two versions, ROM-less or
Flash ROM, the ML675200 and ML67Q5200 devices incorporate an advanced dual processor core architecture featur-
ing an ARM7TDMI™ 32-bit RISC CPU core and a Teak™ 16-bit DSP core.
The CPU-DSP architecture offers system developers both performance and flexibility. The ARM7TDMI RISC core pro-
vides 32-bit performance for application level software with access to general purpose I/O. The DSP core offers the nu-
merical processing power dedicated to repetitive tasks such as MP3 encoding/decoding.
In addition to the two processor cores, the ML675200 and ML67Q5200 devices offer a wide variety of integrated pe-
ripherals, allowing system designers to implement a complete MP3 system requiring minimum external devices. Among
these useful features are a USB 1.1 device controller, 32 Kbytes of SRAM, serial UART ports, GPIO, timers, and analog
channels. Other powerful features include a 4-channel DMA controller for efficient data movement, a PLL circuit, a built-
in controller for external memory, and a built-in voice Codec.
