  • Publication number: 20260155078
    Abstract: A pixel circuit includes a control transistor for driving current for a pixel and a pulse width modulation circuit to supply a control signal to the control transistor. The pulse width modulation circuit switches ON/OFF the control transistor with the control signal to control an emission period of the pixel in one frame period. The pulse width modulation circuit switches ON/OFF a driving transistor that outputs the control signal, using a gray-level data voltage from a control circuit, a first ramp signal, and a second ramp signal steeper than the first ramp signal. The second ramp signal is used in control for a low gray-level range including the minimum gray level and not used in control for a high gray-level range including gray levels higher than the low gray-level range. The first ramp signal is used in at least the control for the high gray-level range.

  • Publication number: 20250377896
    Abstract: The present invention is to prevent speculative execution by a malicious program and reduce a size of a branch prediction buffer. Security IDs of several bits associated with an execution context are registered in a context table, and an instruction address executed in the past and a security ID at the time of execution are stored in a branch prediction buffer. The branch prediction mechanism searches for an entry in the branch prediction buffer with the instruction address of the branch prediction target and the security ID associated with the execution context at the time of branch prediction, and responds to an instruction address generator with a branch target address of the matching entry. The number of bits of the security ID is smaller than the number of bits of the execution context and a program ID that identifies a process included in the execution context.
