Then, when a remaining time up to a target time point goes to the operatable range of a timer 1,100, time difference data is sent to a data bus 400 and timer operation is started. Thus, the output signal of the small time base error can be obtained.SOGA JUNJI...
This was the CPU member of a set of four integrated circuits called the MCS-4, which was originally designed for use in a calculator but was marketed as a “programmable controller for logic replacement.” The 4004 is referred to as a 4-bit microprocessor since it processed only 4 bits ...
The processor interrupt line is monitored by the controller, and with the next interrupt (e.g., a timer event or incoming data), the controller reactivates the processor clock. 3.5 Microprocessor Interface Chip The processor interface (ARMIF) device is the bridge between the microprocessor bus ...
The gated clock signal is also sent as an output to the external controller such as an FPGA. There are two internal registers dedicated to transmission in the C-SPI. The transfer register consists of a 46-bit transmit register and a 32-bit receive register. The transmit register serves the...

Athlon II X2 CPUs integrate memory controller that works with DDR3 and DDR2 memory. DDR3 memory is supported only when the processors are used in socket AM3 motherboards. Despite the fact that the package of all Athlon II X2s has 938 pins, or two less pins than the package of socket...

The MPC7450 consists of a processor core, 32-Kbyte separate L1 instruction and data caches, a 256-Kbyte L2 cache (512-Kbyte for MPC7457 and 1 Mbyte for the MPC7448), and an internal L3 controller with tags that support a glueless backside L3 cache through a dedicated high-bandwidth ...
(not implemented on MPC745) — Internal L2 cache controller and tags; external data SRAMs — 256K, 512K, and 1 Mbyte two-way set-associative L2 cache support — Copy-back or write-through data cache (on a page basis, or for all L2) — Instruction-only mode and data-only mode — ...
