A microprocessor employing a DSP unit and an instruction decode unit is provided. The instruction decode unit is configured to detect an instruction field included with an instruction, and to dispatch instructions having the instruction field to the DSP unit. The DSP unit performs DSP functions, ...
In order for an application running in the User space to run a privileged instruction (in the kernel space), it initiates a system call to the operating system's API. There are many different types of system calls.Answer and Explanation: Three important types of user mode to kernel mode ...
ADDING COMPLEX INSTRUCTION EXTENSIONS DEFINED IN A STANDARDIZED LANGUAGE TO A MICROPROCESSOR DESIGN TO PRODUCE A CONFIGURABLE DEFINITION OF A TARGET INSTRUCTION SET, AND HDL DESCRIPTION OF CIRCUITRY NECESSARY TO IMPLEMENT THE INSTRUCTION... An automated processor design tool uses a description of ...
Dual-CPU SoCs may broadly operate in two modes: Lock Step Mode (LSM): CPUs in both the SoRs execute the same instruction cycle by cycle and any differences between the outputs of the CPUs indicates a fault and triggers a reaction to prevent propagation of the fault and to put the microco...
(1) The lowest-level instructions that directly control a microprocessor. A single machine-language instruction typically translates into several microcode instructions. In modern PC microprocessors, the microcode is hardwired and can’t be modified. Some RISC designs go one step further by completely...
Megahertz (MHz) Abbreviation for megahertz. One MHz represents one million cycles per second. The speed of microprocessors, called the clock speed, is measured in megahertz. For example, a microprocessor that runs at 200 MHz executes 200 million cycles per second. Each computer instruction requires...

Shift-based control logic is used, in an exemplary embodiment, to implement in a microprocessor a circular prefetch queue that stores variable length instructions and transfers four instruction bytes at a time to an instruction decoder. The prefetch queue (10) includes a 16 byte sequential prefetch...
The embedded computing domain can claim at least an order of magnitude more instruction-set architectures (ISA) than the designers of desktops and servers employ for general-purpose computing. Embedded ISAs are offered in a variety of configurations and frequencies; listing all the available devices ...
VLC also supports DVD, VCD and various streaming protocols and can be used as a server to stream in unicast or multicast. VLC is available for many different operating systems including Windows, […] VLIW Short for Very Long Instruction Word, a microprocessor design technology. A chip with ...
