February 14th 2001. Fujitsu Microelectronics Europe is releasing its "Leo" FR-V (Fujitsu RISC-VLIW) chip, based on the FR-V architecture announced last year. The "Leo" chip is designed around Fujitsu’s FR500 core and dedicated purely to the European navigation marketplace.

Co-ordinated by Fujitsu Microelectronics in Frankfurt (FME), the design of the chip is being carried out by Fujitsu Microelectronics in Israel (FMIS), where the well-known SparcLite was produced. Built using the powerful FR500, 32 bit, 4-way VLIW core with media and graphics enhancements, "Leo" is 100% software compatible with Fujitsu’s MB93501 and is both modular and expandable, with the Memory Management Unit being ARM compatible with Windows CE support.

The device operates at a low cost to the system, with an internal frequency of 266MHz, and features an external flexible and simple 32bit system bus operating at 66MHz, 1.8V, and a set of generic and automotive specific peripherals.

Fujitsu’s FR-V architecture is exceptional as it is able to execute parallel instructions. The compiler rather than the processor is responsible for guaranteeing simultaneous issuing of each packet. "Leo" features six execution units on its processor: two integer units; two floating point units and two media execution units, all running in parallel, and its compiler decides which unit is going to carry out a command using the VLIW (very long instruction word) concept.

The CPU core provides a peak performance of 1064 MIPS/1.064 GFLOPS/4256 MOPS @ 266 MHz (integer operation, floating-point and media), providing the possibility for more functionality and/or lower frequency operation.

Integrated within the design is an advanced SDRAM controller with a maximum bandwidth of 1Gbyte/sec. This is over an extended temperature range of -40 degrees C to 85 degrees C.

The chip design includes 2 caches - a 4-way, dual ported 16KB Instruction Cache, and a 4-way, dual ported 16KB Data Cache which is non blocking, and has write back or write through functions. A wide variety of peripheral functions are also featured and include: 4 x UART; 2 x CAN; SIO; I2C; 18 x GPIO; 3 x Timer; Watchdog; 2 x PWM; 3 x Interval timer; 8 x Interrupts; RTC and a Graphic Display Controller which is supported by direct connection to Fujitsu’s Cremson. In addition to these an interface to a MOST transceiver of 25MB/s is also included which allows the possibility of connecting multimedia over an optical Bus.

Designed using 0.18 micron technology, the chip operates from a supply voltage of 1.8V internal/3.3V external, and has a power consumption of just 2.5W at a frequency of 266MHz. Power management features of slow and stop mode are included which can be used to lower the current, a rare feature. The device is housed in a 320 pin FBGA, and JTAG and Boundary scan test is applied to all I/O pins except for the SDRAM.

Fujitsu offers its customers a complete solution with ASIC’s, Flash memories, DVD and GDC’s also available for navigation applications, which are compatible with the new FR-V device. It is anticipated that Leo will be available at the end of CY2001, and a follow on device is also planned which will provide a single chip integrated CPU/Graphic controller function.
