EP9315 is a highly integrated system-on-chip processor that paves the way for next-generation consumer and industrial electronic products. The EP9315 features an advanced 200 MHz ARM920T processor design with a memory management unit (MMU) that supports Linux®, Windows CE® and many other embedded operating systems. The ARM920T's 32-bit microcontroller architecture, with a five-stage pipeline, delivers impressive performance at very low power.
The 16 KB instruction cache and 16 KB data cache provide zero-cycle latency to the current program and data, or they can be locked to guarantee no-latency access to critical instructions and data. For applications with instruction-memory size restrictions, the ARM920T's compressed Thumb instruction set provides space efficiency and maximum external instruction memory usage.
The ARM920T core is augmented by the MaverickCrunch™ coprocessor. This coprocessor greatly accelerates the ARM920T's single- and double-precision integer and floating-point processing capabilities.
With the EP9315's built-in IDE interface, the processor can connect directly with multiple hardware devides such as hard drives, CD drives and DVD drives. This significantly reduces BOM costs and board size.
The EP9315's user interface capabilities include a 2-D graphics accelerator that improves performance by handling block copy, block fill, line draw and bit blit. Resolutions of up to 1024 x 768 (XGA) are supported. Touchscreen, keypad and high quality sound (SPI, I²S and AC '97) complete the EP9307's strong user interface features.
A high-performance 1/10/100 Mbps Ethernet media access controller (MAC) is included, along with external interfaces to SPI, I²S audio, Raster/LCD, IDE storage peripherals, keypad and touchscreen. A three-port USB 2.0 full-speed host (OHCI), running at 12 Mbps, and three UARTs are included as well.
Cirrus Logic's embedded processor products are complemented by a range of complete operating systems. Both Microsoft® Windows CE.NET® and Linux® solutions are available with total driver support.
