Description

• Up to 1000 MMACS using an internal 266 MHz clock at 1.2 V. A multiply-accumulate

operation includes a multiply-add instruction with the associated data move and pointer

update.

• 4 data ALUs.

• 16 data registers, 40 bits each.

• 27 address registers, 32 bits each.

• Hardware support for fractional and integer data types.

• Very rich 16-bit wide orthogonal instruction set.

• Up to six instructions executed in a single clock cycle.

• Variable-length execution set (VLES) that can be optimized for code density and

performance.

• JTAG port designed to comply with IEEE® Std 1149.1™.

• On-chip emulator (OCE) module with real-time debugging capabilities.

The high performance extended core delivers up to 1000 MMACS using 4 ALUs running up to

266 MHz, including:

• SC1400 core processor.

• 64 KB multi-port SRAM (M1) accessed by the SC1400 core with no wait states.

• 16 KB, 16-way instruction cache (ICache).

• Programmable instruction fetch unit.

• Write buffer (4-entry).

• Extended core interface module.

The large internal memory space totals 88 KB:

• 64 KB of M1 memory.

• 16 KB ICache.

• 8 KB boot ROM accessible from the SC1400 core.

• DDR memory controller.

• Glueless interface to 133 MHz DDR-RAM (synchronous and half of internal clock).

• 14-bit external address bus supporting up to 1 GB.

• 16- or 32-bit external data bus.

• Memory controller supports:

• Byte enables for 32-bit external data bus.

• Data pipeline to reduce data set-up time for synchronous devices.

AHB-Lite crossbar switch, allowing up to four parallel data transfers between four master ports

and six slave ports, where each port connects to an AHB-Lite bus.

Multi-channel DMA controller:

• Up to 32 time-multiplexed channels.

• Priority-based time-multiplexing between channels using 32 internal priority levels

• Priorities can be fixed or round-robin.

• A flexible channel configuration:

• All channels support all features.

• All channels connect to the slave ports on the crossbar.

External interfaces and control modules managed on the advanced peripheral bus (APB)

including:

• Time-division multiplexing (TDM) module supporting up to 128 channels.

• Two 16-bit quad timers.

• RS-232 interface/universal asynchronous receiver/transmitter (UART).

• I2C interface.

• Up to 37 general-purpose input/output (GPIO) signals.

• Interrupt controller to handle external interrupt functions (input and output).
